TL;DR: RK3588 Custom Edge Computing Board
SHENZHEN, China, September 12, 2026 - The WF-C3588-E7 board cleared the Longgang aging bench this week in lot 240, a 9,930-unit run for Los Angeles, United States, and moved straight to the container yard.
AndroidSBC export paperwork update on the nine-variant WF-C3588 custom board line serving Los Angeles, United States. What United States importers get from the WF-C3588 programme is a single Rockchip RK3588 silicon across nine custom motherboard variants, all built at the Wanlin Longgang plant in Shenzhen. The 6 TOPS NPU, the 8K@60fps decoder and the dual Gigabit Ethernet stack are common to every board; the I/O layout, memory fit and enclosure reference are tuned to the project. The export desk issues one certification pack per lot covering CE, FCC, UKCA, RoHS and IEC 62368-1.

WF-C3588-E7 Technical Specifications
| Parameter | AndroidSBC WF-C3588-E7 (Custom Edge AI Computing Board) | Industry Average |
|---|---|---|
| Processor | Rockchip RK3588 octa-core 4x Cortex-A76 2.4GHz + 4x Cortex-A55 1.8GHz (8nm) + 6 TOPS NPU | Cortex-A55 gateway without NPU |
| NPU precision | INT4 / INT8 / INT16 / FP16 / BF16 / TF32 mixed precision | INT8 only |
| Model toolchain | RKNN-Toolkit2 quantization from PyTorch, ONNX, TensorFlow, Caffe and MXNet | Cloud-only deployment |

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-C3588-E7 (Custom Edge AI Computing 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 United States importers sourcing the WF-Series, the 16GB + 64GB (WF-C3588-E7-C) variant is the typical configuration for the custom edge AI computing programmes use case, with a sustained weekly capacity of 5,000 pcs/wk on the Longgang line.
Challenges in Sourcing Custom Edge AI Computing Board for United States Buyers
Buyers in Los Angeles who have run the custom edge ai computing board category for a few years tend to stop shopping on price alone. The Rockchip RK3588 allocation is the real constraint, and it is the reason a 9,930-unit order can look cheap on paper and expensive in a slipped quarter. Then comes the firmware question. The hardware spec is straightforward to verify; whether the board holds a credential-locked stack through a 72-hour loop and a field OTA is a different test, and it is normally the Los Angeles buyer's warehouse that discovers the answer.
Documentation is the third item on the list. A CE mark without a matching Declaration of Conformity and Technical File is not a marking problem, it is a customs problem, and it tends to surface after the goods are already on the water. AndroidSBC's approach is to close the gap at the factory gate. The custom variant is assembled on the Longgang line, the burn-in record is traceable per unit barcode, and the CE, FCC and IEC 62368-1 test reports are dated inside twelve months and shipped with the lot. The nine WF-C3588 variants span edge AI inference boxes, AI gateways, machine vision inspection, video analytics appliances, smart city nodes, factory AI retrofits, and edge computing servers, with three memory configurations per variant for Los Angeles buyers who need a standard custom SKU rather than a from-scratch build.
On the United States side, the destination file matters as much as the board specification. In the United States FCC Part 15 authorisation is required and an FCC ID applies to radio modules, while UL or ETL listing is usually demanded by the retail channel. The export desk prepares the destination-market file covering FCC Part 15 authorisation with an FCC ID for radio modules and a UL or ETL listing, administered by FCC / UL, and releases it with the standard multi-market pack (CE, FCC, UKCA, RoHS, REACH). The lot is booked into Port of Los Angeles on the Los Angeles to Yantian lane.
WF-C3588-E7 Application Scenarios
The WF-C3588 line fits nine custom motherboard lanes, with the WF-C3588-E7 (Custom Edge AI Computing Board) as the lead SKU for Los Angeles and United States programmes:
- Retail analytics box: a mall operator counts dwell time and demographics locally across hundreds of fanless nodes.
- Factory vision retrofit: an assembly line adds defect classification without touching the PLC, using the multi-model pipeline.
- Smart city intersection: a traffic programme runs vehicle and pedestrian analytics on one sealed node per junction.
- Power grid substation: a utility reads gauges and thermal cameras locally over dual GbE back to the SCADA room.
- Agriculture edge node: a farm runs crop and pest models offline where connectivity is seasonal at best.
- Healthcare kiosk analytics: a clinic chain triages queues with on-device vision and no personal data leaving the site.
- Campus safety system: a university estate runs perimeter and corridor analytics with local alarm relay.
- Transit hub appliance: a station operator streams platform analytics to a control room over the optional 5G seat.
Partnership Models for Los Angeles Buyers
AndroidSBC opens the WF-C3588 to United States partners through three structures, and a single agreement can draw on more than one:
- 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.
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 United States 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: Standard-variant samples ship in 1-3 days from stock, so your engineering team can start integration while the custom scope is being quoted. A custom run follows a 15-30 day mass-production window after schematic and stack-up sign-off. MOQ is 5,000 units per shipment on standard variants; on custom configurations the MOQ is negotiable against volume commitments, and small batch orders are accepted for pilot phases. A twelve-month framework agreement with monthly lot releases brings the per-lot MOQ down further.
What certifications does a custom board need for United States, 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 United States 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 United States 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-E7 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.
