TL;DR: RK3588 ONNX to RKNN Conversion
SHENZHEN, China, September 11, 2026 - Wanlin Manufacturing Group pushed lot 409 of the WF-RK3588-D5 board out of the Longgang plant this week, 27,475 units for Houston, United States, with the export declaration naming Longgang as the place of origin.
AndroidSBC site report from running WF-RK3588 NPU installations serving Houston, United States. AndroidSBC is opening the full WF-RK3588 to United States: nine variants on the Rockchip RK3588 platform with 6 TOPS NPU, 8K H.265 decode, dual Gigabit Ethernet and up to 32GB of LPDDR5. Every variant ships from the Wanlin Longgang facility with OEM branding available, ODM carrier design handled in-house, and per-lot CE, FCC, UKCA, RoHS and IEC 62368-1 documentation.

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-RK3588-D5 (8K Digital Signage and Video Wall) 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 8GB + 64GB (WF-RK3588-D5-A) variant is the typical configuration for the 8K digital signage and multi-screen video wall use case, with a sustained weekly capacity of 5,000 pcs/wk on the Longgang line.
Global 8K Digital Signage and Video Wall Market Trends
- 8K digital signage player: WF-RK3588-D5 decodes 8K@60fps H.265 content from onboard eMMC or the M.2 NVMe over HDMI 2.1.
- Display and signage refresh cycles: a longer content loop and a higher panel resolution now define the refresh trigger. The WF-RK3588-D5 board carries that headroom without a board change.
- Conference room display: WF-RK3588-D5 carries the meeting content plus the local annotation stream on the same board.
The 8K Digital Signage and Video Wall commentary has shifted from unit growth to supply reliability, and that shift favours suppliers who control their own SMT and burn-in lines.
The common thread in United States is that single orders are being replaced by blanket agreements with a monthly release, because a programme that has to survive a twelve-month window cannot absorb an allocation gap in the middle of it.
WF-RK3588-D5 Application Scenarios
The WF-RK3588 line fits nine NPU application lanes, with the WF-RK3588-D5 (8K Digital Signage and Video Wall) as the lead SKU for Houston and United States programmes:
- 8K digital signage player: WF-RK3588-D5 decodes 8K@60fps H.265 content from onboard eMMC or the M.2 NVMe over HDMI 2.1.
- Multi-screen video wall: WF-RK3588-D5 drives four independent 4K screens over HDMI 2.1, DP 1.4, eDP, and MIPI-DSI.
- Conference room display: WF-RK3588-D5 carries the meeting content plus the local annotation stream on the same board.
- Airport flight information display: WF-RK3588-D5 holds the flight database plus the live video overlay at frame rate.
- Hotel lobby digital signage: WF-RK3588-D5 ingests the property CMS push and the weather plus flight feeds.
- Retail store digital signage: WF-RK3588-D5 runs the estate CMS push-pull plus the audience analytics dashboard.
- Interactive digital signage: WF-RK3588-D5 hosts the touch loop and the gesture model on the NPU.
- Quad display video wall: WF-RK3588-D5 distributes four independent screens at independent refresh rates.
Partnership Models for Houston Buyers
For Houston distributors and brand owners, AndroidSBC opens the 8k digital signage and video wall 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.
Does the WF-RK3588 line run Android or Linux, and what NPU framework stack is supported?
Answer: Both. AndroidSBC prebuilt Android 12 and Android 13 firmware images that boot on every WF-RK3588 variant, with Android 14 builds available on request. Linux distributions (Ubuntu 22.04 LTS, Debian 12, Yocto Kirkstone, Buildroot) load the Rockchip RKNN-Toolkit2 runtime so the 6 TOPS NPU is usable from day one. The same silicon carries the Android build on the WF-RK3588-D5 signage player and the Yocto build on the WF-RK3588-V1 industrial vision processor, which is a deployment breadth that United States importers rarely get from one supplier.
What is the 6 TOPS triple-core NPU on the WF-RK3588 actually used for in production?
Answer: Three workloads that have already shipped at scale. On the WF-RK3588-E0 the NPU drives retail analytics (people counting, dwell time, demographic classification) at 25fps per stream. On the WF-RK3588-V1 the same silicon runs machine-vision defect classification at line speed on a factory floor. On the WF-RK3588-N3 it carries 16-channel AI surveillance analytics (person, vehicle, behaviour) on a fanless board. Each variant is tuned for its workload, but the silicon is the same, and that is what makes one supplier file cover nine deployment categories for United States buyers.
Can AndroidSBC handle CE, FCC, UKCA, RoHS, REACH and IEC 62368-1 paperwork for United States?
Answer: Yes. AndroidSBC ships a Declaration of Conformity plus a Technical File with every lot. The file contains the CE test reports (EN 55032 plus EN 55035 EMC, EN IEC 62368-1 safety), the FCC Part 15 report, the UKCA dossier where relevant, the RoHS 2.0 report, and the REACH declaration, all dated within the prior twelve months. Where a United States market needs an additional national mark, the export desk will confirm coverage before the order is confirmed rather than after.
What are the MOQ and lead time for a first order on the WF-RK3588?
Answer: 5,000 units per shipment on standard configurations, four weeks to sample and six weeks to mass produce. Where a United States partner signs a twelve-month blanket order, the MOQ per release becomes negotiable and the line will accept variant-mixed purchase orders.
Does AndroidSBC support custom Android ROM, custom Linux, or custom NPU model porting?
Answer: Custom ROM, custom Linux, and custom NPU model porting are all part of the ODM tier. That covers proprietary Android services, a locked-down launcher, Ubuntu, Debian, Yocto or Buildroot images, BSP ports for custom carriers, and RKNN-Toolkit2 model quantization from PyTorch, ONNX, TensorFlow or Caffe. Source access is released under NDA, and the Longgang engineering desk carries the port so the partner is not left with an unmodified vendor BSP.
What about software updates and long-term support on the WF-RK3588?
Answer: Wanlin commits to a minimum seven-year supply window across the WF-RK3588 line. Security patches are back-ported across the Android, Ubuntu LTS, Debian LTS and Yocto tracks for as long as the board is in production, and AndroidSBC provides OTA update infrastructure for partners who need to push firmware to field-deployed units. NPU model builds are versioned on the Wanlin side so a partner that re-trains a model can push the new RKNN file through the same OTA channel without a board swap.
Can AndroidSBC ship 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 the WF-RK3588?
Answer: Target DOA is 0.3 percent across twelve months. RMA works by returning the WF-RK3588-D5 unit to Longgang with its burn-in barcode; replacements ship inside ten business days. Since each unit is traceable to its burn-in record, partners typically receive a root-cause note with the replacement rather than a silent credit.
