Case Study: Berlin Trading Company Sourcing Manager Sourcing Success
George Mitchell, a Trading Company Sourcing Manager in Berlin, walked into the supplier search with three hard requirements: real RK3588 silicon, per-model certificate files and a factory that would match the panel timings. The first quotes he received were rebranded TV boxes with a single HDMI output and no certificate files for the export shipment.
Following a visit to the SMT line, George Mitchell selected AndroidSBC as their RK3588 dual display board manufacturing partner. The buyer picked AndroidSBC because the quote included the dual display bring-up and the boot configuration service as standard, not as a paid extra.
- In-house testing: every board passes power-on, dual-output display, touch and burn-in tests before it leaves the line
- Document pack: certificate files, BSP packages, datasheets, interface drawings and user manuals are packed with each export order
- Firmware customization: boot logo, autostart applications, kiosk mode, dual display mode defaults and pre-installed apps configured before shipment
The integrator standardized one dual display board across three screen products and cut the spare-parts list from fourteen boards to one.
Problem Analysis & Field Report: Why Global Buyers Need RK3588 Dual Screen POS Terminal Board
A dual display board looks simple until it has to run 7x24 in a sealed cabinet, hold extended mode through power cuts and keep touch alive while both screens play 4K. A QSR brand in Berlin shipped kiosks where the peripheral mapping changed between firmware updates, and field technicians had to reconfigure printers and scanners on every unit.
Field case: A retailer in Berlin moved to RK3588 dual display POS boards with fixed serial mapping. Checkout kept running through payment terminal updates, and support tickets fell within a month.
Why it matters for global buyers:
- Both screens under load: independent VOP outputs keep touch and video alive together, which is where cheap boards fail first
- Peripheral stability: fixed USB and serial mapping survives firmware updates, so printers and scanners stay configured
- Cart-driven content: the second screen follows the order flow, turning a status display into a selling surface
- Offline operation: cached content and logged transactions keep unattended terminals selling through network gaps
- Line throughput: frozen customer displays mean abandoned carts, so recovery without a reboot is a revenue feature
Display buyers tend to price a dual display board twice: once on the quote and once in lost screen uptime. A board that shows both screens in the demo but drops the second panel during a 4K loop on a hot afternoon is not cheaper, it is a second purchase in disguise. The same logic applies to frame synchronization, temperature range and document completeness, because each one shows up later as a field visit or a customs hold.

RK3588 Dual Display Board OEM Process: From Inquiry to Shipment
Most AndroidSBC projects follow the same path: define the display mix, lock the silicon and OS, approve samples wired to your panels, then move to aged and tested production. A standard OEM project then follows 8 steps:
- Tell Us Your Target Market - North America, Europe, Middle East, Southeast Asia, East Asia, South Asia, Oceania, Africa or Latin America; different markets may require different certification, OS licensing and connector configurations
- Define the Two Screens - panel models, interfaces, resolutions, orientation and touch needs are fixed against your enclosure and software
- Lock the Software Stack - Android, Ubuntu, Debian, Yocto or Buildroot, plus dual display mode defaults, autostart, kiosk mode and peripheral mapping for your application
- Verify Documentation - for applicable models, request and verify the certificate files, temperature validation and BOM information before ordering
- Sample Evaluation - samples wired to your exact panels are evaluated on your bench or in the field before mass production, with the same BOM used in the approved units
- Confirm Production - after specifications, commercial terms and OEM details are confirmed, the project proceeds to production
- Quality Inspection - boards are inspected and tested with power-on, dual-output display, touch and 48-hour aging procedures according to applicable production and quality-control standards
- Shipment - products are prepared for shipment FOB, CIF or DDP according to the agreed logistics requirements

Frequently Asked Questions
Q: Why one board for both POS screens instead of two players?
A: One RK3588 drives the operator and customer displays in extended mode, so the checkout app pushes line items to the customer screen with no second device, no extra license and no sync work.
Q: Which peripherals are supported?
A: Receipt printers, cash drawers, barcode scanners and cameras connect through USB and RS232, and the serial mapping stays fixed across firmware updates.
Q: Can the customer screen show promotions between orders?
A: Yes, the app can switch the secondary display to an idle playlist when no order is active, then return to order details at checkout.
Q: Is face payment supported?
A: The NPU runs face verification locally on supported builds, and the camera connects over USB. Payment compliance is handled by the customer payment stack.
Q: What is the lead time for branded POS boards?
A: Stock boards ship in 1-3 days. Branded builds with custom boot logo and pre-installed POS software run about 15-20 days for small batches.
