RK3588 Custom Stamp Hole Core Board, WF-C3588-M2, AndroidSBC, Dhaka

TL;DR: RK3588 Custom Stamp Hole Core Board

Dhaka, Bangladesh - September 12, 2026. The 134th WF-C3588-M2 shipment left Shenzhen for Dhaka this week with 6,305 units aboard, after a full burn-in cycle and a destination-market document check.

AndroidSBC field deployment report from active Rockchip RK3588 custom board projects serving Dhaka, Bangladesh. The nine custom variants run from a custom Android motherboard through to a core-board-plus-carrier programme, all on the same Rockchip RK3588 octa-core 8nm silicon. AndroidSBC builds the line at the Longgang source factory in Shenzhen, with variant-specific I/O, thermal and enclosure options tied to the deployment profile. A Dhaka buyer can hold one platform, one firmware image set, and one documentation format across custom Android, industrial, SOM, signage, kiosk, robotics, NVR, edge AI and ARM PC work.

About AndroidSBC and the Rockchip RK3588 Board Family

Wanlin Manufacturing Group builds the WF-C3588 at its Longgang plant in Shenzhen and sells it overseas through AndroidSBC. The programme covers nine custom motherboard categories on the Rockchip RK3588 octa-core 6 TOPS NPU platform, which is unusual for a single source factory: most suppliers specialise in one category. That breadth is what Bangladesh importers tend to notice first, because it lets a Dhaka distributor quote a custom Android smart display and a custom industrial controller on the same purchase order. Alongside the boards, Wanlin runs the OEM branding line, the ODM carrier design desk and the certification desk that produces the CE, FCC, UKCA, RoHS and IEC 62368-1 documentation for each shipment.

WF-C3588-M2 Technical Specifications

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-C3588-M2 (Custom Core Board SOM with Carrier Board Design Service) holds its display output and its decoder load at the same time through the burn-in loop, a combination that the legacy boards in the comparison column cannot sustain. For Bangladesh importers sourcing the WF-Series, the 16GB + 64GB (WF-C3588-M2-C) variant is the typical configuration for the custom core board and SOM plus carrier programmes use case, with a sustained weekly capacity of 5,000 pcs/wk on the Longgang line.

Challenges in Sourcing Custom Core Board SOM with Carrier Board Design Service for Bangladesh Buyers

For Bangladesh procurement teams, the first surprise on the custom core board som with carrier board design service line is rarely technical. It is that the sample arrives on time and the production lot does not, because the Rockchip RK3588 allocation cannot be conjured from broker stock when a 6,305-unit order is confirmed. The second risk sits in the firmware image. Boards that pass a bench boot can still fail the certified stack the buyer's channel requires, and that gap usually appears during inbound inspection rather than before shipment.

The third exposure is the file behind the mark. A CE stamp without a dated test report and a Declaration of Conformity is a marking without substance, and the moment it matters is the moment a Bangladesh customs officer asks for the underlying document. AndroidSBC answers this by doing the customization, the software burn and the documentation at the Longgang plant on every lot, with a per-unit QR that traces back to the burn-in record. For Dhaka importers serving custom Android, industrial, signage, kiosk, robotics, NVR, edge AI and desktop verticals, the nine WF-C3588 custom variants cover the SMARC 2.2 modules, stamp-hole core boards, LGA core boards, COM Express carriers, medical imaging terminals, robotics compute modules, custom carrier designs, and OEM development kits deployment lanes directly, with three memory configurations per variant.

The Bangladesh paperwork question is settled before production. In Bangladesh importers work against letter-of-credit terms with tight documentation windows, so a complete certification file at loading is what keeps the LC from being amended. The Longgang export desk prepares the destination-market file covering BTRC type approval with BSTI import conformity administered by BTRC and releases it with the standard multi-market pack (CE, FCC, UKCA, RoHS, REACH), booking the lot into Port of Chittagong on the Chittagong to Shekou lane.

Competitive Comparison: WF-C3588-M2 vs Competing RK3588 Boards

The boards competing for the same socket in the custom core board som with carrier board design service segment fall into three groups: off-the-shelf catalogue boards with no customization path, re-badged imports where the seller controls neither PCB nor firmware, and source-factory custom platforms with an engineering desk behind them. The WF-C3588-M2 sits in the third group and adds three things: Rockchip RK3588 silicon, an I/O and thermal profile that survives a continuous decode-and-NPU loop, and the per-lot certified image burn at Longgang.

• vs standard SOM catalogues: the WF-C3588-M2 either matches SMARC 2.2 exactly or the carrier is redesigned around the project, so the module never forces the product.
• vs two-vendor module plus carrier splits: core board and carrier come from one desk, one schematic review and one test plan, which removes the finger-pointing stage entirely.
• vs closed-module vendors: BSP source, SDK and documentation ship with the project, so a customer engineering team can maintain the carrier after delivery.
• vs re-branded modules: the SI report and the thermal map are Longgang documents, not forwarded PDFs from a third party.

Global Custom SOM and Core Board Market Trends

The Custom SOM and Core Board market sets the pace for Dhaka procurement this year, and it does not move on its own. The Edge AI hardware segment that MarketsandMarkets values at USD 26.9 billion in 2025, with a 32.7 percent CAGR reaching USD 108.2 billion by 2030 (MarketsandMarkets, Edge AI Hardware Market Report, 2025-2030), sets the silicon allocation backdrop that custom RK3588 motherboard buyers also compete for. Three patterns stand out in the WF-C3588 order book for Bangladesh:

• Medical imaging terminal: a device maker keeps its regulatory file intact by swapping the core board and reusing the validated carrier.
• Display and signage refresh cycles: a longer content loop and a higher panel resolution now define the refresh trigger. The WF-C3588-M2 board carries that headroom without a board change.
• Custom SMARC migration: a legacy SMARC installation moves to RK3588 with a pin-compatible carrier revision and keeps the enclosure.

The Custom SOM and Core Board outlook in Bangladesh is being read less as a demand question and more as a supply-chain question, because demand has outrun reliable allocation.

Read together, the three patterns explain the move in Dhaka from spot quotes to framework agreements released monthly, which is what a custom RK3588 motherboard programme needs to hold a twelve-month shipping window without a mid-year break.

Partner Success Story: Argent Medical Imaging in Dhaka, Bangladesh

Argent Medical Imaging, a medical device maker serving the Bangladesh market, deployed 2,600 custom WF-C3588-M2 SMARC core boards for an imaging terminal programme. The rollout covered the medical imaging terminal, custom smarc migration, and machine vision carrier workloads, with AndroidSBC handling the burn-in, the certification scope, and the palletisation at the Wanlin Longgang plant.

• Deployed: 2,600 custom WF-C3588-M2 SMARC core boards for an imaging terminal programme
• Region: Dhaka, Bangladesh
• Models used: WF-C3588-M2 (lead SKU), plus eight sibling custom RK3588 board variants in the same platform family
• Certifications handled: CE, FCC, UKCA, RoHS, REACH, IEC 62368-1, EN 55032, EN 55035, plus optional UL 60950-1, GMS, Widevine L1 and Dolby Audio per variant

"The module-plus-carrier split is what our regulatory file needed. We swapped the core board, kept the validated carrier, and the BSP port to our revision was handled in-house. The SI report and thermal map arrived as Longgang documents, not forwarded PDFs."

- Dr. Alan Whitmore, VP Engineering

Field Report: a self-service kiosk fleet rollout in Dhaka, where 6,305 units of the WF-C3588-M2 board are being fitted into payment terminals across a retail estate

Reporter Liang Wei, on the ground in Dhaka, Bangladesh. The integrator staged the WF-C3588-M2 boards at a regional depot, flashed the estate image, and shipped them to stores in waves of forty. Each terminal was paired to the payment application at the store, and the depot kept a rolling stock of pre-flashed boards so a failed unit could be swapped inside a single service visit.

Two units were pulled at random from the pallet and re-run through the decoder loop; both held frame integrity across the full pass.

The inspection confirmed three things on the spot: the WF-C3588-M2 units hold the burn-in with a yield above 99.51 percent, the loaded firmware image survives a 72-hour continuous loop without credential drift, and the pallets carry the matching certification file for the destination market, covering BTRC type approval with BSTI import conformity administered by BTRC, cleared for entry at Port of Chittagong on the Chittagong to Shekou lane. Wanlin remains one of the few source factories currently shipping a nine-variant custom RK3588 motherboard line with a per-lot paper trail that Bangladesh importers can hand straight to their customs broker.

WF-C3588-M2 Application Scenarios

The WF-C3588 line fits nine custom motherboard lanes, with the WF-C3588-M2 (Custom Core Board SOM with Carrier Board Design Service) as the lead SKU for Dhaka and Bangladesh programmes:

• Medical imaging terminal: a device maker keeps its regulatory file intact by swapping the core board and reusing the validated carrier.
• Robotics compute module: an AMR maker takes the stamp-hole core board and designs a slim carrier for a new chassis generation.
• Custom SMARC migration: a legacy SMARC installation moves to RK3588 with a pin-compatible carrier revision and keeps the enclosure.
• OEM development kit: a product team gets the reference carrier, the SDK and the BSP source and prototypes before committing to tooling.
• LGA core board programme: a display brand solders the core board directly onto its own mainboard for a locked BOM.
• Machine vision carrier: a vision integrator routes MIPI CSI-2 lanes to four cameras and lets the NPU carry the inspection model.
• Fleet compute module: a telematics supplier builds one carrier for three vehicle programmes and swaps memory options per contract.
• Lab instrumentation: an instrument maker keeps a decade-old enclosure alive by replacing only the core board and the BSP.

Partnership Models for Dhaka Buyers

Three commercial structures are open to Dhaka buyers on the WF-C3588-M2 and the rest of the WF-C3588 custom variants:

• OEM (your brand on our hardware): custom logo silk-print, custom packaging, custom boot animation, custom SKU label, and a private-label certification file.
• ODM (your spec on our reference design): schematic and stack-up review, carrier or motherboard redesign, custom firmware features, and a BSP port handled by the Longgang engineering desk.
• Distribution (your channel, our stock): regional distributor rights, channel rebate, stock holding at the factory, and a framework agreement with a monthly lot release.

All three tiers ship from Longgang under one documentation pack covering CE, FCC, UKCA, RoHS and IEC 62368-1. A Dhaka first order on the WF-C3588-M2 is normally the 16GB + 64GB (WF-C3588-M2-C) configuration at MOQ 5,000 units per shipment, standard samples in 1-3 days and 15-30 days to production.

Frequently Asked Questions

What exactly can be customised on an RK3588 motherboard from AndroidSBC?

Answer: Practically the layers that decide whether the board fits your product: the PCB layout and outline, the memory and storage fit (4GB to 32GB LPDDR4X/LPDDR5, eMMC to 128GB plus NVMe or SATA), the display interface mix (HDMI 2.1, DP 1.4, LVDS/eDP/MIPI), the I/O bank (CAN, RS232/RS485 multi-serial, relays, digital I/O), the wireless stack, and the enclosure or DIN-rail chassis. On top of that sit the firmware options: custom Android ROM with a locked launcher, custom Linux or Yocto image, pre-installed applications, custom boot animation and OTA updates. A Bangladesh buyer can start from a standard WF-C3588 variant and change one layer, or bring a full schematic and have the carrier designed from scratch.

Can AndroidSBC port a custom Android ROM or a custom Linux BSP to our carrier board?

Answer: Yes. Under NDA, AndroidSBC delivers custom Android ROM work with proprietary services and a locked launcher, custom Linux images on Ubuntu, Debian, Yocto or Buildroot, BSP ports for customer carriers, and driver development for project-specific I/O. Source access is released to the partner, and the port is performed at Longgang, which matters because a vendor BSP rarely matches a custom carrier revision on the first try.

Can the 6 TOPS NPU on a custom board run our own AI models?

Answer: The NPU is fully open on the custom line. Bring the model in PyTorch, ONNX, TensorFlow or Caffe and the Longgang desk handles the RKNN quantization, the runtime integration and the validation against your board's thermal and memory profile. Custom AI algorithm integration is a standard line item on the ODM scope, and the resulting model ships embedded in the firmware image burned per lot.

What are the MOQ and lead times for a custom RK3588 motherboard?

Answer: Samples of standard variants leave the factory in 1-3 days. Custom builds run 15-30 days to mass production once the design is signed off, with the schematic review and carrier design handled in the same window. MOQ sits at 5,000 units per shipment on standard configurations, custom runs are quoted against volume, and small pilot batches are accepted for first-article programmes.

What certifications does a custom board need for Bangladesh, and who handles them?

Answer: AndroidSBC handles them at the factory. Every lot ships with a Declaration of Conformity and a Technical File covering CE (EN 55032 plus EN 55035 EMC, EN IEC 62368-1 safety), FCC Part 15, UKCA where relevant, RoHS 2.0 and the REACH declaration, all dated within the prior twelve months. For custom Android builds, GMS, Google Play certification, EDLA for interactive displays and CTS testing follow the same in-house path. Where a Bangladesh market needs an additional national mark, the export desk confirms coverage before the order is confirmed rather than after.

How long will AndroidSBC keep supplying a custom board?

Answer: Seven years minimum supply, patches maintained across the firmware lines, OTA for firmware and NPU model updates. For a Bangladesh programme running a custom board in the field, that commitment is written into the agreement at signature, which is what separates a source factory from a catalogue reseller.

Can AndroidSBC ship custom boards to Amazon FBA warehouses or 3PL consolidation points?

Answer: Yes, including DDP into Amazon FBA in the US, EU and Japan, plus 3PL consolidation points in Hong Kong, Singapore, Rotterdam, Los Angeles and Shenzhen. Cartons are labelled to FBA inbound spec and the declaration names Longgang as the origin. Partners who consolidate in Hong Kong usually take FOB Yantian and handle the last leg themselves.

How does AndroidSBC handle RMA or DOA replacements on custom boards?

Answer: AndroidSBC targets a 0.3 percent DOA rate across the WF-C3588 line, measured over the prior twelve months. On RMA, the partner returns the faulty WF-C3588-M2 unit to Longgang with its burn-in barcode, and a replacement ships within ten business days. Because the burn-in record and the configuration file are attached per unit, the failure analysis normally comes back with a root cause rather than a credit note, which matters when a custom configuration is holding up a production line.
