RK3588 Custom Industrial Board Supplier, WF-C3588-N6, AndroidSBC, Dhaka

TL;DR: RK3588 Custom Industrial Board Supplier

SHENZHEN, China, September 12, 2026 - Wanlin Manufacturing Group pushed lot 347 of the WF-C3588-N6 board out of the Longgang plant this week, 23,125 units for Dhaka, Bangladesh, with the export declaration naming Longgang as the place of origin.

AndroidSBC regulatory bulletin on CE, FCC, UKCA, RoHS and IEC 62368-1 coverage for the WF-C3588 serving Dhaka, Bangladesh. The line spans custom Android motherboards at the entry variant through core-board-plus-carrier work at the SOM end, all on the same Rockchip RK3588 silicon with 6 TOPS NPU, 8K H.265 decode and up to 32GB of LPDDR5. AndroidSBC ships the full range from the Wanlin Longgang plant, and Dhaka buyers can mix custom variants inside a single framework agreement rather than opening a new supplier file for each product line.

About AndroidSBC and the Rockchip RK3588 Board Family

AndroidSBC is the export brand of Wanlin Manufacturing Group, a Shenzhen source-factory group that has spent more than a decade building custom OEM and ODM boards on Rockchip silicon. The line this release covers is the WF-C3588: nine custom motherboard variants built on the same Rockchip RK3588 octa-core 8nm platform with 6 TOPS NPU and 8K H.265 video, covering custom Android motherboards, custom industrial boards, core board and SOM carrier design, custom signage and video wall boards, custom kiosk and POS boards, custom robotics controllers, custom NVR boards, custom edge AI boards, and custom ARM PC and NAS boards. Wanlin's Longgang plant in Shenzhen builds the WF-C3588 for Bangladesh OEM, integrator and distributor programmes. For a Dhaka buyer the practical value of the line is that one silicon and one supplier file cover nine custom categories.

WF-C3588-N6 Technical Specifications

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-C3588-N6 (Custom NVR and Security Surveillance Board) 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 + 128GB (WF-C3588-N6-C) variant is the typical configuration for the custom NVR and surveillance programmes use case, with a sustained weekly capacity of 5,000 pcs/wk on the Longgang line.

Challenges in Sourcing Custom NVR and Security Surveillance Board for Bangladesh Buyers

The custom nvr and security surveillance board sourcing question that Dhaka distributors keep coming back to is continuity across quarters. The Rockchip RK3588 requires a dedicated wafer slot, and a 23,125-unit order placed against broker inventory often turns into a two-month slip with no warning. Then comes the software layer. A board that boots is not a board that holds a certified stack under a 72-hour loop, and Bangladesh buyers typically find the difference in their own warehouse rather than at the factory.

The third exposure is paperwork. Factories that stamp marks without holding the underlying test reports leave the importer to produce a Technical File after the fact, which is exactly when the container is sitting in a bonded yard. AndroidSBC runs the custom board build, the certified image burn, the burn-in record and the certification file inside the Longgang plant, so the lot arrives complete rather than in pieces. The nine variants in the WF-C3588 cover smart NVRs, multi-camera recorders, face recognition terminals, access control, turnstile controllers, intercom stations, LPR cameras, perimeter systems, and behaviour analytics and each one carries three memory configurations, which keeps Dhaka and Bangladesh buyers on standard custom SKUs for most requirements.

For Bangladesh specifically, the file travels with the goods. 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. AndroidSBC prepares the BTRC type approval with BSTI import conformity documentation for BTRC, attaches the standard multi-market pack (CE, FCC, UKCA, RoHS, REACH), and consigns the lot to Port of Chittagong on the Chittagong to Shekou lane.

Competitive Comparison: WF-C3588-N6 vs Competing RK3588 Boards

Three families of board chase the same custom nvr and security surveillance board socket. The first is catalogue hardware with fixed memory and fixed I/O, the second is re-badged stock where nobody owns the schematic, and the third is a real custom platform built by the factory that runs the SMT line. The WF-C3588-N6 belongs to the third family and separates itself on Rockchip RK3588, on customization depth from schematic to firmware, and on a certified image burned per lot.

• vs generic NVR chipsets: the WF-C3588-N6 carries the analytics on the 6 TOPS NPU, so the recorder does not ship a cloud subscription as a hidden dependency.
• vs PC-based recorders: a fanless board replaces a workstation-class recorder and survives gate cabinets and outdoor enclosures.
• vs camera-side AI splits: one board class covers the NVR, the face terminal and the turnstile, which simplifies spares and firmware across one estate.
• vs unbranded surveillance boards: the per-lot file and the burn-in record are what an installer needs when a perimeter line has to answer for uptime.

Global Custom NVR and Surveillance Board Market Trends

Buyers in Dhaka are reading the Custom NVR and Surveillance Board curve before they commit to a custom nvr and security surveillance board programme. MarketsandMarkets reports the Edge AI hardware segment at USD 26.9 billion in 2025 with a 32.7 percent CAGR to USD 108.2 billion by 2030 (MarketsandMarkets, 2025-2030), used here as the RK3588-class silicon baseline rather than as a number for this category. That baseline breaks into three practical demand patterns for the WF-C3588 in Bangladesh:

• City surveillance NVR: a municipal programme records and analyses sixteen channels per node on a fanless board.
• Display and signage refresh cycles: a longer content loop and a higher panel resolution now define the refresh trigger. The WF-C3588-N6 board carries that headroom without a board change.
• License plate recognition gate: a parking operator pairs LPR on the NPU with relay control for the barrier.

What the Custom NVR and Surveillance Board data does not show is the operational cost of a supply break, which is why Dhaka buyers increasingly weight supplier continuity above a marginal price difference.

The common thread in Bangladesh is that single orders are being replaced by blanket agreements with a monthly release, because a custom board programme that has to survive a twelve-month window cannot absorb an allocation gap in the middle of it.

Partner Success Story: Ostra Vision Labs in Dhaka, Bangladesh

Ostra Vision Labs, a machine vision integrator serving the Bangladesh market, deployed 4,900 custom WF-C3588-E7 edge AI boards for factory inspection lines. The rollout covered the city surveillance nvr, license plate recognition gate, and retail loss prevention workloads, with AndroidSBC handling the burn-in, the certification scope, and the palletisation at the Wanlin Longgang plant.

• Deployed: 4,900 custom WF-C3588-E7 edge AI boards for factory inspection lines
• Region: Dhaka, Bangladesh
• Models used: WF-C3588-N6 (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
• Logistics: FOB Yantian with the Wanlin Group Longgang source factory named on the export declaration, entering Port of Chittagong via the Chittagong to Shekou lane

"Our defect model went from ONNX to RKNN inside a week with their engineering desk, not a forum thread. The boards run four cameras per cell with classification at line speed, and the per-unit barcode makes every RMA a root-cause report instead of a swap."

- Daniel Reyes, VP Product

Field Report: a control room in Dhaka where 23,125 units of the WF-C3588-N6 board are driving a video wall installation

Reporter Sun Ming, on the ground in Dhaka, Bangladesh. The integrator mounted the WF-C3588-N6 boards in the control room rack and spent two days on display mapping and colour matching across the wall. The boards held four independent outputs through the full commissioning window without a thermal throttle, and the operator console was handed over on schedule.

Pallet weights were checked against the packing list at the dock, and the container was sealed 25 minutes before the cut-off.

The inspection confirmed three things on the spot: the WF-C3588-N6 units hold the burn-in with a yield above 98.72 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-N6 Application Scenarios

The WF-C3588 line fits nine custom motherboard lanes, with the WF-C3588-N6 (Custom NVR and Security Surveillance Board) as the lead SKU for Dhaka and Bangladesh programmes:

• City surveillance NVR: a municipal programme records and analyses sixteen channels per node on a fanless board.
• Face recognition terminal: a corporate lobby runs face-based entry with the camera and the reader bank on one multi-serial profile.
• License plate recognition gate: a parking operator pairs LPR on the NPU with relay control for the barrier.
• Perimeter detection site: a critical facility runs behaviour analytics at the fence line with local alarm relay.
• Building intercom station: a property network runs door stations on the wide-temperature variant outside the lobby.
• Retail loss prevention: a chain correlates POS events with camera analytics on the same recorder board.
• Turnstile controller: a stadium estate drives turnstiles and readers from the same board family as its recorders.
• Construction site security: a contractor deploys sealed NVRs with 4G failover where no cabling exists.

Partnership Models for Dhaka Buyers

For Dhaka distributors and brand owners, AndroidSBC opens the custom nvr and security surveillance board line under three contract shapes:

• 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.

Whichever structure a Bangladesh partner selects, the lot leaves Longgang with the same certification pack and the same test flow. The standard entry point on the WF-C3588-N6 is the 16GB + 128GB (WF-C3588-N6-C) configuration at MOQ 5,000 units per shipment, 1-3 days to sample and 15-30 days to mass production.

Frequently Asked Questions

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

Answer: Everything from the copper up. Custom PCB and PCBA, custom I/O routing, custom memory and storage configuration, custom display and camera interfaces, custom thermal profile from commercial to -40C to 85C industrial, and custom branding including silk-printed logo, packaging, SKU label and boot animation. The firmware side covers custom Android (GMS or AOSP), Ubuntu, Debian, Yocto and OpenHarmony builds with BSP ports handled by the Longgang engineering desk rather than handed to the buyer as an unmodified vendor drop.

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

Answer: Custom ROM, custom BSP and custom SDK work are all part of the ODM tier. AndroidSBC builds the Android image (12, 13, 14 or 15, GMS or AOSP), ports the Linux BSP to your carrier revision, and releases the SDK modules your team needs under NDA. The engineering desk carries the port itself, so a Bangladesh integrator is not left debugging an unmodified vendor BSP against a carrier it was never designed for.

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

Answer: Yes. The RK3588 NPU runs INT4, INT8, INT16, FP16, BF16 and TF32, and AndroidSBC supports model deployment through the Rockchip RKNN-Toolkit2, with quantization from PyTorch, ONNX, TensorFlow, Caffe and MXNet. As part of the ODM tier, the engineering desk walks your model from framework to RKNN format and validates it on the actual board configuration you are shipping, not a reference unit. Model files are versioned so a retrained model can be pushed to field units through OTA without a board swap.

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

Answer: The structure is deliberately two-speed: 1-3 days for a standard-variant sample so a Bangladesh project team can start immediately, and 15-30 days to mass production on a custom run once the design freezes. MOQ is 5,000 units per shipment on standard variants, with custom and pilot quantities negotiated against the annual volume commitment.

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

Answer: Certification is part of the customization scope, not an afterthought. The in-house file covers CE, FCC Part 15, UKCA, RoHS 2.0, REACH and IEC 62368-1 with test reports dated inside twelve months, plus GMS and EDLA tracks for custom Android and display products. The file is built for the exact configuration you ship, which matters for a custom board because a test report on a different memory fit is not a valid report at all.

How long will AndroidSBC keep supplying a custom board?

Answer: Seven years minimum, written into the framework agreement. The RK3588 platform carries a long industrial lifecycle, and Wanlin commits to the supply window, to security patches across the Android, Ubuntu LTS, Debian LTS and Yocto tracks, and to OTA update infrastructure for field-deployed units. For a custom board that is the whole point of going to a source factory: the product lifecycle is a contract term, not a hope.

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

Answer: Yes. AndroidSBC ships DDP to Amazon FBA warehouses in the US, EU and Japan, and to nominated 3PL consolidation points in Hong Kong, Singapore, Rotterdam, Los Angeles and Shenzhen. Carton labelling and pallet configuration follow FBA inbound requirements, the export declaration names the Wanlin Longgang source factory as the place of origin, and each pallet carries a per-unit barcode that traces back to the burn-in record for downstream RMAs.

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

Answer: Target DOA is 0.3 percent across twelve months. RMA works by returning the WF-C3588-N6 unit to Longgang with its burn-in barcode; replacements ship inside ten business days. Since each unit is traceable to its burn-in and configuration record, partners typically receive a root-cause note with the replacement rather than a silent credit.
