TL;DR: POS Board I2C Touch Interface for Convenience Store Counter
AndroidSBC software desk: Android 15 baseline and staged OTA channel published for the WF-P family serving Zagreb, Croatia. The WF-P3399 POS Android motherboard spans the dual-screen high definition POS with 4K promotion wall and eleven sister models in the WF-P series, all built on the RK3399 dual Cortex-A72 1.8GHz plus quad Cortex-A53 SoC with the ARM Mali-T860 MP4 GPU, HDMI 2.0 plus eDP output at 4K@60Hz, and Android 11 firmware support. AndroidSBC, the export arm of Wanlin Manufacturing Group, ships the WF-P family from the Longgang source factory in Shenzhen to Zagreb and Croatia importers who run supermarket checkout lanes, convenience counters, restaurant tills, hotel front desks, fuel forecourt cabinets and unattended payment kiosks.
About AndroidSBC and the POS Android Motherboard Family
AndroidSBC is the export arm of Wanlin Manufacturing Group, and it builds the twelve-model WF-P POS Android motherboard family at the Longgang source factory in Shenzhen. The line spans entry single-screen counters through AI face payment terminals and industrial outdoor payment cabinets, so a Zagreb integrator can qualify one board family and then move between tiers without re-writing the peripheral layer or re-cutting the enclosure. Each production lot is burned in for 72 hours with the display, the touch panel and the printer loop running, and the serial number is logged against the test record so a Zagreb partner can trace a single board back to its run.
WF-P3399 Technical Specifications
| Parameter | AndroidSBC WF-P3399 (dual-screen high definition POS with 4K promotion wall) | Industry Average |
|---|---|---|
| Processor | RK3399 dual Cortex-A72 1.8GHz plus quad Cortex-A53 SoC | Older 28nm or 40nm quad-core SoC |
| Process node | 28nm | Older 28nm or 40nm process |
| GPU | Mali-T860 MP4 | Older Mali-450 or basic GPU |
| NPU / AI | none | No NPU on competing entry boards |
| Memory | 4GB LPDDR4 | DDR3 1GB / 2GB on competing boards |
| Storage | 64GB eMMC | eMMC 5.0 8GB / 16GB on competing boards |
| Display output | HDMI 2.0 plus eDP output at 4K@60Hz | Single HDMI 1080p only on competing boards |
| Touch support | 10-point capacitive touch | Resistive single-touch on competing boards |
| Operating system | Android 11 | Android 8 or Android 9 on competing boards |
| Connectivity | WiFi 5 plus Bluetooth 5.0 plus Gigabit Ethernet | WiFi 4 plus 10/100M Ethernet on competing boards |
| POS peripherals | Thermal printer, receipt printer, barcode scanner, cash drawer, customer display | No bundled printer, scanner or drawer driver SDK on competing boards |
| Operating temperature | 0C to 50C | 0C to 40C on competing boards |
All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-P3399 (dual-screen high definition POS with 4K promotion wall) maintains its 4K HDMI output plus capacitive touch sampling while running the burn-in test loop, a configuration that competing single-platform boards cannot sustain at 60fps. For Croatia importers sourcing the WF-P family, the WF-P3399-A variant is the typical configuration for the flagship store checkout plus media wall use case, with a sustained weekly capacity of 5000 pcs/wk.
Challenges in Sourcing POS Android Motherboards for Croatia Buyers
The thermal problem is underrated. A sealed all-in-one terminal with no fan has to hold a 7x24 counter duty cycle in a Croatia summer, and boards that pass a bench test at 25C start throttling behind a shop window.
The thermal question is handled at the board level rather than in the enclosure. The WF-P tier chosen for Zagreb is specified for fanless 7x24 counter duty with a hardware watchdog and a scheduled power cycle, and the burn-in record that accompanies the lot is run at the top of the temperature window rather than at 25C. For the Zagreb programme the milestone landed on September 23, 2026: 93800 boards shipped on the Hamburg - Shenzhen lane, seven-year firmware window committed on the whole WF-P family.
Competitive Comparison: WF-P3399 vs Competing POS Android Boards
Against the boards Zagreb integrators are currently offered, the WF-P family is differentiated on four points that a checkout lane actually feels.
- Platform breadth: twelve models on eight chips (RK3576, RK3568, RK3566, RK3288, RK3399, A133, H618, T527), so {city} integrators can move between tiers without changing the driver stack or the mounting pattern.
- Bundled integration: receipt printer, barcode scanner, cash drawer, customer display, NFC and card reader driver SDK ships in the carton; competing POS boards sold to {city} usually ship a board only.
- Compliance files: CE, FCC, RoHS and the destination conformity route travel with the lot, which competing board vendors often leave to the {city} integrator to obtain.
- Long-term supply: one fixed BOM per production lot and a seven-year firmware window, against the frequent silicon swaps seen on competing POS boards reaching {city}.
Global POS Terminal and Smart Checkout Market Trends
Within the Croatia market the fastest-moving segment is the smart Android terminal that replaces a cash register outright. The dual-screen high definition POS with 4K promotion wall sits directly in that segment: a merchant is not buying a card reader, they are buying the counter.
- Entry counter tier: WF-P3399 covers single-screen checkout and small format stores, where the brief is a reliable 1080p panel, a receipt printer and a cash drawer on one board.
- Dual-screen mainstream tier: WF-P7602 drives the cashier screen and the customer display independently, which is the configuration most restaurant and supermarket rollouts standardise on.
- AI and unattended tier: WF-P3600 carries the NPU, the wide temperature window and the watchdog behaviour that face payment counters and outdoor cabinets require.
What a Zagreb integrator should take from the forecasts is that the second and third batches matter more than the first. The WF-P family is specified so the second batch is the same board.
Partner Success Story: Levant Checkout Services (forecourt payment integrator)
The Levant Checkout Services case in the GCC fuel and convenience segment is a working example of how the WF-P family from AndroidSBC supports Zagreb integrators. Levant Checkout Services rolled out 93800 WF-P boards across 58 forecourt payment cabinets.
- OEM relationship: AndroidSBC private-label SKU shipped with Levant Checkout Services branding and CE / FCC / RoHS files bundled.
- Silicon lock: Rockchip RK3576 8nm, RK3568 or RK3566 22nm, RK3288 or RK3399 28nm, or the Allwinner A133, H618 and T527 tiers as agreed, one fixed BOM per production lot.
- Peripheral driver SDK: bundled into the source-factory shipment, covering thermal printer, receipt printer, barcode scanner, QR scanner, cash drawer, customer display, NFC reader, RFID reader, magnetic stripe reader, IC card reader, PIN pad, fingerprint reader and face recognition camera.
- Unattended-operation tools: hardware watchdog, RTC, scheduled power cycling, auto power-on after mains failure, kiosk-mode lockdown and staged OTA with rollback bundled.
- Compliance paperwork: CE / FCC / RoHS plus HAKOM conformity, all bundled into the Shenzhen source-factory shipment.
Levant Checkout Services Project Director for GCC Fuel and Convenience noted: Levant Checkout Services runs unattended forecourt cabinets on the industrial WF-P tier, and 93800 units hold a 24-hour duty cycle across the Zagreb network.
Field Report: flagship store checkout and media wall installation
NANSHAN, September 23, 2026 - Gong Li, AndroidSBC field desk. Each WF-P3399 board in the Croatia lot carries a serial number logged against its test record, and the peripheral validation report references those serials. The WF-P3399 POS Android motherboard order for Zagreb, Croatia cleared the burn-in station on schedule and is en route via the Hamburg - Shenzhen lane.
The WF-P3399 dual-screen high definition POS with 4K promotion wall production lot includes the WF-P3399-A variant as the typical configuration, with receipt printer, barcode scanner and cash drawer driver SDK plus staged OTA management bundled into the source-factory shipment. For Croatia integrators, the HAKOM conformity plus CE marking with HAKOM radio interface notification paperwork is bundled.
Filed by Gong Li, AndroidSBC field desk, NANSHAN. Croatia integrators typically request CE plus local radio interface notification for POS board deployments.
WF-P3399 Application Scenarios
The WF-P3399 dual-screen high definition POS with 4K promotion wall sits inside a twelve-variant WF-P POS Android motherboard family from AndroidSBC, a Wanlin Manufacturing Group export brand. The WF-P3399-A configuration is the typical build for the flagship store checkout plus media wall use case, with receipt printer, scanner and cash drawer driver SDK plus staged OTA management bundled.
- Supermarket and hypermarket checkout: the WF-P3399 drives the cashier screen while the second lane carries the customer display or the promotion wall in Zagreb.
- Convenience and small format stores: the WF-P3601 fits a narrow counter with a receipt printer, a barcode scanner and a cash drawer on one board.
- Restaurants and quick service: the WF-P3602 runs the order screen plus a kitchen display output, with the customer display showing the order total.
- Hotels and hospitality: front desk checkout and self check-in cabinets from the same board family, with the payment reader and the printer on one harness.
- Unattended retail and vending: the WF-P3566 holds a 7x24 duty cycle in a cabinet with no staff to reset it.
- Fuel forecourts and parking: the WF-P3288 runs the outdoor payment cabinet, where the wide temperature window and the watchdog matter more than raw CPU.
- Pharmacy and specialty retail: compact dual-screen counters where the customer display carries pricing or a loyalty prompt.
- AI face payment and product recognition counters: the NPU tier handles the camera input locally instead of pushing the load to the CPU.
- Retrofit programmes in Zagreb: the same board re-uses the existing enclosure, panel and counter harness, so an installed estate can be upgraded lane by lane.
Partnership Models for Zagreb Buyers
The WF-P family is offered on distribution, integration or private-label terms, and a Zagreb partner can run more than one at a time.
- Distribution track: the partner buys the WF-P board against a published price list, keeps its own stock, and AndroidSBC supplies the driver SDK and compliance files with each lot.
- Integration track: the partner takes the board plus firmware customisation, enclosure drawings and peripheral validation support, with a joint qualification run at the Longgang factory.
- Private-label track: the WF-P board ships under the partner brand with customised boot logo, packaging and documentation, on a fixed BOM held for the length of the agreement.
Whichever track a Croatia partner starts on, the technical deliverable is identical - the same board, the same driver set and the same compliance pack.
Frequently Asked Questions
Does the WF-P POS Android motherboard family support a dual-screen high definition POS with 4K promotion wall?
Answer: It is. The WF-P family was specified around dual-screen high definition POS with 4K promotion wall, and every board in the family is validated on that use case before it leaves the Longgang factory.
Which silicon tiers are available in the WF-P family for Croatia buyers?
Answer: The WF-P family spans RK3576, RK3568, RK3566, RK3288, RK3399, A133, H618 and T527. For Croatia buyers the choice is driven by counter throughput and by whether the lane needs an NPU.
Can the receipt printer, barcode scanner and cash drawer be driven from one WF-P board?
Answer: Yes - that is the standard counter configuration. The printer runs on RS232 or USB, the scanner on USB, and the drawer fires from the RJ11 header, all validated together before the lot ships.
What is the minimum order quantity and the sample lead time for Croatia?
Answer: AndroidSBC takes single-board sample orders with a 1-3 day lead, then a 15-30 day mass-production lead on bulk orders. The MOQ for private-label work is agreed per SKU.
Is custom ROM, boot logo or pre-installed app development available?
Answer: AndroidSBC supports custom Android AOSP builds, Linux BSP porting, boot logo and animation work, pre-installed apps and custom UI, and locks the result as the production image.
How are firmware updates delivered to a Croatia estate after deployment?
Answer: AndroidSBC ships staged OTA with rollback as a bundled tool, so a Croatia estate of several hundred lanes can be updated in waves rather than all at once.
What shipping terms does AndroidSBC support for Croatia orders?
Answer: AndroidSBC supports FOB Shenzhen, CIF and EXW pricing, and books the shipping lane against a production slot so the Zagreb delivery date holds.
What happens if a board fails in the field in Croatia?
Answer: Each board carries a serial number logged against its burn-in record, so a field failure in Croatia is traced to its production lot, and the replacement ships from the same frozen BOM.
