RK3588 Linux Ubuntu Custom Board, WF-C3588-R5, AndroidSBC, Dhaka

TL;DR: RK3588 Linux Ubuntu Custom Board

SHENZHEN, China, September 12, 2026 - Wanlin Longgang released a 13,120-unit WF-C3588-R5 lot for Dhaka, Bangladesh this week, the 393rd run booked against the Rockchip RK3588 allocation.

AndroidSBC procurement notice on the WF-C3588 custom board supply position serving Dhaka, Bangladesh. The WF-C3588 line is a custom motherboard programme built on the Rockchip RK3588 octa-core platform (4x Cortex-A76 at 2.4GHz plus 4x Cortex-A55 at 1.8GHz on 8nm) with a triple-core NPU delivering 6 TOPS of INT8 inference, 8K H.265 decode and up to 32GB of LPDDR4X or LPDDR5. AndroidSBC, the export arm of Wanlin Manufacturing Group, builds nine custom variants at the Longgang source factory in Shenzhen for Dhaka and Bangladesh buyers: WF-C3588-A0 custom Android motherboards, WF-C3588-I1 custom industrial boards, WF-C3588-M2 core boards and SOMs with carrier design, WF-C3588-S3 custom signage and video wall boards, WF-C3588-K4 custom kiosk and POS boards, WF-C3588-R5 custom robotics controllers, WF-C3588-N6 custom NVR boards, WF-C3588-E7 custom edge AI boards, and WF-C3588-P8 custom ARM PC and NAS boards.

About AndroidSBC and the Rockchip RK3588 Board Family

The WF-C3588 exists because Bangladesh buyers kept asking one supplier for two different custom board tiers. Wanlin Manufacturing Group answered by putting nine custom variants on the same Rockchip RK3588 octa-core silicon with 6 TOPS NPU, 8K H.265 video and up to 32GB of LPDDR5. The group runs SMT, burn-in and pre-compliance testing in one Longgang building in Shenzhen, and the export desk holds the certification file rather than passing it back to the importer. For a Dhaka distributor that means one vendor file, one document format and one MOQ structure across the custom variants it sells.

WF-C3588-R5 Technical Specifications

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-C3588-R5 (Custom Robotics and AGV Control 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 8GB + 32GB (WF-C3588-R5-B) variant is the typical configuration for the custom robotics controller programmes use case, with a sustained weekly capacity of 5,000 pcs/wk on the Longgang line.

Challenges in Sourcing Custom Robotics and AGV Control Board for Bangladesh Buyers

The recurring problem for Dhaka and Bangladesh buyers sourcing a custom robotics and agv control board is not the headline unit price, it is whether the allocation actually holds. The Rockchip RK3588 needs its own wafer slot, and brokers who quote from stock frequently cannot honour that slot once a 13,120-unit push lands mid-quarter. The software question follows immediately. The hardware spec sheet is easy to verify; the difference between a board that runs a launcher and a board that holds a certified, credential-locked stack only becomes visible after the first field update.

Documentation closes the list. Buyers in Dhaka have learned to ask for the test reports before the deposit, because a CE mark printed on a carton is worth nothing at the port without the Declaration of Conformity behind it. AndroidSBC handles it by doing the custom I/O build, the software burn and the documentation at the factory: every lot leaves Longgang with the certified image loaded, a unit-level burn-in barcode, and a Technical File that carries the test reports. The nine WF-C3588 custom variants cover AGV controllers, AMR mainboards, service robots, inspection robots, quadruped platforms, SLAM navigation, robot vision, fleet dispatch terminals, and charging stations with three memory configurations each, which means a Dhaka integrator can usually match a customer requirement without a bespoke production run.

Compliance for Bangladesh is handled at the factory rather than after arrival. 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 builds the destination-market file for BTRC type approval with BSTI import conformity administered by BTRC and issues it alongside the standard multi-market pack (CE, FCC, UKCA, RoHS, REACH), with the shipment booked into Port of Chittagong on the Chittagong to Shekou lane.

Competitive Comparison: WF-C3588-R5 vs Competing RK3588 Boards

Three groups of board compete for the custom robotics and agv control board socket. The first is catalogue silicon sold on price with no customization route and no certification file. The second is re-badged stock where the seller cannot produce a schematic or a test report. The third is a genuine custom platform on Rockchip RK3588 with the engineering desk, the burn-in rack and the certification file in one Longgang building. The WF-C3588-R5 sits in the third group.

• vs paired PC-plus-MCU controllers: the WF-C3588-R5 runs vision, navigation and fleet logic on one board and hands only the power stage to the drive electronics.
• vs generic SBC robot builds: the CAN, multi-serial and real-time options come validated on the reference carrier instead of being patched in by the integrator.
• vs cloud-vision robots: SLAM and obstacle detection stay on the 6 TOPS NPU, so the robot keeps navigating when the warehouse WiFi drops.
• vs module resellers: custom I/O changes are executed by the Longgang engineering desk with the test bench that will validate them.

Global Custom Robotics Control Board Market Trends

The Custom Robotics Control Board market is the frame that decides how Bangladesh importers time their custom robotics and agv control board orders. The figure most Bangladesh buyers quote when they argue about allocation is the Edge AI hardware segment, which MarketsandMarkets sizes at USD 26.9 billion in 2025 with a 32.7 percent CAGR to USD 108.2 billion by 2030 (MarketsandMarkets, Edge AI Hardware Market Report, 2025-2030); it is the public proxy for the RK3588-class silicon that custom board buyers compete for, not a forecast for this category. For Dhaka, three buying patterns are shaping the WF-C3588 order book:

• Warehouse AGV fleet: an automation vendor runs SLAM and fleet dispatch on the board with dual GbE back to the coordinator.
• Display and signage refresh cycles: a longer content loop and a higher panel resolution now define the refresh trigger. The WF-C3588-R5 board carries that headroom without a board change.
• Inspection quadruped: a platform maker runs gait control and inspection vision on isolated cores under PREEMPT_RT.

Channel analysts tracking the Custom Robotics Control Board category note that allocation discipline, not unit price, has become the deciding factor for buyers who need a twelve-month programme to hold.

In all three cases, Dhaka buyers are converting spot quotes into blanket orders with a monthly lot release, because a custom motherboard programme that has to hold a twelve-month shipping window cannot tolerate a mid-year allocation break.

Partner Success Story: Kestrel Signage Works in Dhaka, Bangladesh

Kestrel Signage Works, a digital signage OEM serving the Bangladesh market, deployed 9,700 custom WF-C3588-S3 signage boards for a multi-market DOOH and indoor network. The rollout covered the warehouse agv fleet, inspection quadruped, and agriculture robot workloads, with AndroidSBC handling the burn-in, the certification scope, and the palletisation at the Wanlin Longgang plant.

• Deployed: 9,700 custom WF-C3588-S3 signage boards for a multi-market DOOH and indoor network
• Region: Dhaka, Bangladesh
• Models used: WF-C3588-R5 (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 Ningbo-Zhoushan with the Wanlin Group Longgang source factory named on the export declaration, entering Port of Chittagong via the Chittagong to Shekou lane

"We came with a block diagram and a deadline. AndroidSBC turned it into a quad-output carrier with our connector set and our boot animation, and the first production lot landed inside the fifteen-to-thirty-day window they quoted at schematic sign-off."

- Maarten de Vries, Director of Operations

Field Report: a control room in Dhaka where 13,120 units of the WF-C3588-R5 board are driving a video wall installation

Reporter Lin Yu, on the ground in Dhaka, Bangladesh. The integrator mounted the WF-C3588-R5 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.

The line supervisor logged a 41-minute changeover between the WF-C3588-R5 run and the next lot, which is the kind of number that decides whether a mid-quarter top-up order can be absorbed.

The inspection confirmed three things on the spot: the WF-C3588-R5 units hold the burn-in with a yield above 99.35 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-R5 Application Scenarios

The WF-C3588 line fits nine custom motherboard lanes, with the WF-C3588-R5 (Custom Robotics and AGV Control Board) as the lead SKU for Dhaka and Bangladesh programmes:

• Warehouse AGV fleet: an automation vendor runs SLAM and fleet dispatch on the board with dual GbE back to the coordinator.
• AMR delivery robot: a service robot pairs NPU navigation with a custom carrier that routes the sensor stack.
• Inspection quadruped: a platform maker runs gait control and inspection vision on isolated cores under PREEMPT_RT.
• Cleaning robot fleet: a facility operator runs coverage planning and obstacle detection locally with nightly model updates.
• Charging station control: the board coordinates dock sequencing, battery telemetry and fleet handshakes.
• Agriculture robot: a field robot runs row detection on the NPU offline, kilometres from the nearest access point.
• Remote monitoring link: a fleet operator streams diagnostics over the optional 5G seat to a central depot.
• Robot vision retrofit: an older fleet gains NPU vision without replacing the drive electronics.

Partnership Models for Dhaka Buyers

AndroidSBC runs three engagement tiers for Bangladesh importers and brand owners sourcing a custom robotics and agv control board on the WF-C3588 custom line:

• 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.

Every tier draws on the same Longgang line and the same certification desk. A Dhaka first order on the WF-C3588-R5 normally lands on the 8GB + 32GB (WF-C3588-R5-B) configuration at MOQ 5,000 units per shipment, with standard samples in 1-3 days and a 15-30 day mass-production window on custom builds.

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: Yes, and that work stays in-house. The ODM tier covers custom Android ROM builds with proprietary services and launchers, AOSP builds without Google services, and Linux images on Ubuntu, Debian, Yocto or Buildroot. BSP ports for custom carrier boards are executed by the Longgang engineering desk, with SDK and BSP source released to the partner under NDA. The same desk handles driver development for the I/O you added, which is the part that usually stalls when a factory forwards a vendor drop and walks away.

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: That is routine. AndroidSBC delivers DDP into Amazon FBA in the US, EU and Japan and into 3PL consolidation points at Hong Kong, Singapore, Rotterdam, Los Angeles and Shenzhen. Carton and pallet configuration follows FBA inbound rules, and the place of origin on the declaration is the Wanlin Longgang source factory.

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-R5 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.
