TL;DR: 7x24 Continuous Operation Board
SHENZHEN, China, September 10, 2026 - Lot 286 of the WF-RK3288 board cleared final inspection at the Wanlin Longgang plant this week, with 35,015 units consigned to Los Angeles, United States.
AndroidSBC supply-chain sourcing update serving Los Angeles, United States. The line-up runs from the cost-optimised Allwinner A133 commercial display board through to the Rockchip RK3588 eight-core 8K video wall board, with the Allwinner T527 octa-core industrial board and the Rockchip RK3568, RK3566, and RK3288 boards filling the industrial, vision, and POS tiers. AndroidSBC ships all nine from the Longgang source factory in Shenzhen, with the SOM variants (WF-A133S, WF-RK3588S) aimed at Los Angeles and United States buyers who need their own carrier board.
WF-RK3288 Technical Specifications
| Parameter | AndroidSBC WF-RK3288 (POS Terminal and Digital Signage Board) | Industry Average |
|---|---|---|
| Processor | Rockchip RK3288 quad-core ARM Cortex-A17 1.8GHz + Mali-T764 GPU | Dual-core Cortex-A9 1.2GHz |
| Process node | 28nm | 40nm |
| GPU | Arm Mali-T764 (OpenGL ES 3.1, OpenCL 1.1) | Mali-400 MP2 |
| Video decode | H.265 / H.264 4K x 2K hardware decode | 1080p@30fps hard limit |
| Video encode | H.264 1080p@30fps | 720p@30fps encode |
| Display output | HDMI 2.0 + LVDS + eDP dual display | HDMI 1.4 single output |
| Memory | DDR3 2GB / 4GB | DDR3 1GB |
| Storage | 8GB / 16GB / 32GB eMMC 5.1 | 4GB NAND |
| Wireless | Gigabit Ethernet + WiFi + Bluetooth | 100M Ethernet, WiFi 4 |
| Peripheral I/O | Multi-COM, USB HOST, cash drawer and printer port expansion | Limited USB only |
| Thermal range | Commercial grade 0C to 60C, fanless design | 0C to 50C with fan |
| OS support | Android 5.1 / 7.1 / 11 (long-term support image) | Android 5.1 only |
All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-RK3288 (POS Terminal and Digital Signage 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 2GB + 16GB (WF-RK3288-A) variant is the typical configuration for the POS terminal and digital signage use case, with a sustained weekly capacity of 5,000 pcs/wk on the Longgang line.
Challenges in Sourcing POS Terminal and Digital Signage Board for United States Buyers
The first thing United States procurement teams learn about the pos terminal and digital signage board category is that quotation speed and delivery reliability are inversely related. The Rockchip RK3288 needs a wafer slot that a broker cannot create, so the fastest quotes are often the ones attached to the least secure allocation. 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 United States paperwork question is settled before production. 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 Longgang 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), booking the lot into Port of Los Angeles on the Los Angeles to Yantian lane.
WF-RK3288 Application Scenarios
The WF-Series fits nine application lanes, with the WF-RK3288 (POS Terminal and Digital Signage Board) as the lead SKU for Los Angeles and United States programmes:
- POS terminal: WF-RK3288 drives the main display plus the customer-facing LVDS panel from one board.
- Cash register: WF-RK3288 handles the printer and cash drawer expansion through the multi-COM header.
- Digital signage: WF-RK3288 loops the 4K x 2K content over HDMI 2.0.
- Advertising machine: WF-RK3288 runs 24/7 poster playback with scheduled power control.
- Self-service kiosk: WF-RK3288 pairs the touch panel with the USB peripheral stack.
- Digital menu board: WF-RK3288 holds the dual display output for the menu and the promotion panel.
- Industrial Android terminal: WF-RK3288 runs the fanless 0C to 60C enclosure.
- Multimedia player: WF-RK3288 plays the 1080p loop from onboard eMMC without a network link.
Partnership Models for Los Angeles Buyers
Three commercial structures are open to Los Angeles buyers on the WF-RK3288 and the rest of the WF-Series:
- 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-Series support certified Android TV or Google Mobile Services?
Answer: Yes, on the platforms where that matters. The WF-H618 runs Android 12 (ATV 12) with Google Mobile Services and is ready for Android 14 (ATV 14). AndroidSBC burns the GMS, Widevine L1, and Dolby Audio stack at the Longgang plant on every production lot, so the board ships ready for Netflix, Disney Plus, Amazon Prime Video, HBO Max, Apple TV, and YouTube TV. The commercial and industrial boards in the line use the AOSP image with an optional GMS build for partners who need it.
What is the difference between the nine WF-Series models?
Answer: Nine boards, seven silicon platforms, two of them modules. WF-A133 and WF-H618 and WF-T527 are the Allwinner entries for commercial display, OTT TV, and industrial edge respectively. WF-RK3588, WF-RK3568, WF-RK3566, and WF-RK3288 are the Rockchip entries for 8K video wall, industrial edge, machine vision, and POS. WF-A133S and WF-RK3588S are board-to-board SOM modules sized for customers who want to design the carrier themselves. Each board carries three memory configurations.
Can AndroidSBC handle CE, FCC, UKCA, RoHS, and REACH paperwork for United States?
Answer: That is handled in-house. Each lot leaves Longgang with a Declaration of Conformity and a Technical File holding the CE, FCC Part 15, UKCA, RoHS 2.0, and REACH documents, all dated inside twelve months. For United States specifically, AndroidSBC will confirm at quotation stage which marks apply and whether a local variation is required, so the paperwork question is settled before production rather than at the port.
What are the MOQ and lead time for a first order?
Answer: MOQ is 5,000 units per shipment for the standard memory configuration of any WF-Series board. Sample lead time runs four weeks and mass production six weeks. Partners who prefer a twelve-month blanket order with a monthly lot release can negotiate the MOQ down, and mixed-platform orders on one purchase order are accepted.
Does AndroidSBC support custom Android ROM or custom Linux development?
Answer: Yes. Under NDA, AndroidSBC delivers custom Android ROM work with proprietary services, custom Linux images on Yocto or Debian or Buildroot, and BSP ports for customer carriers. The engineering desk at Longgang performs the port itself, which matters because an unmodified vendor BSP rarely matches a customer carrier revision.
What about software updates and long-term support?
Answer: Seven years minimum supply, with security patches maintained across the Android and Linux firmware lines. Partners who deploy at scale can use the AndroidSBC OTA infrastructure to update field units. For long-lifecycle programmes in POS, signage, or industrial control, the support term is written into the framework agreement at signature.
Can AndroidSBC ship 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, and Los Angeles. 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?
Answer: AndroidSBC targets a 0.3 percent DOA rate across the WF-Series, measured over the prior twelve months. On RMA, the partner returns the faulty WF-RK3288 unit to Longgang with its burn-in barcode, and a replacement ships within ten business days. Because the burn-in record is attached per unit, the failure analysis normally comes back with a root cause rather than a credit note.
