| Multi-platform POS family | Four carriers, two contracts | One enclosure, one BSP train, one MOQ |
OEM/ODM workflow: 8 steps from kickoff to first article
Below is the actual OEM/ODM workflow a payment terminal manufacturer in Madrid walks through when commissioning a custom POS Android motherboard from AndroidSBC. No step is a placeholder.
- Day 0-2 — Requirements intake. A 90-minute call captures the counter format, the I/O map, the peripheral list, the OS choice, the payment and fiscal rules, the language list and the volume profile. Output: a one-page requirements sheet.
- Day 3-6 — Feasibility study. AndroidSBC engineers validate the SoC choice (RK3576, RK3568, RK3566 or RK3288), the carrier I/O map, the BSP availability, the certification gap and the thermal envelope. Output: a feasibility report with go / no-go on each customization.
- Day 7-10 — Schematic and PCB layout. The AS-RK3576-PMP-CUS carrier board is laid out on a 6-layer stack-up with the customer's I/O map. Output: schematic and PCB review package.
- Day 11-14 — BSP porting. Android, Linux, Ubuntu, Debian, Kylin OS, UOS or OpenHarmony BSP is ported to the customer's OS choice, with kiosk-mode locking, secure boot, offline store support and fiscal packs where needed. Output: a BSP build for the customer's evaluation team.
- Day 15-18 — Sample fabrication. Five to ten engineering samples are fabricated at the Shenzhen source factory, with conformal coating and stencil rework as required. Output: samples shipped to the customer by air.
- Day 19-21 — Customer evaluation. The customer's evaluation team runs thermal, EMC, transaction latency, peripheral integration, payment acceptance and field-replication tests. Output: an evaluation report with sign-off or change requests.
- Day 22-23 — Design freeze and mass-production tooling. Any change requests are absorbed, the design is frozen, and mass-production tooling is opened at the source factory. Output: a frozen Gerber and a frozen BOM.
Twenty-nine days from kickoff to first article. Ninety-five days from kickoff to mass production. This is the OEM/ODM rhythm that the payment terminal manufacturer in Europe learns to expect from a Shenzhen source factory that does this work for a living.
Frequently asked questions
What is the MOQ for a custom POS Android motherboard?
Answer: 150 units for OEM (a re-spin of an existing carrier board), 500 units for ODM (a from-scratch PCB layout). Sample orders of five units are accepted with an engineering report.
How long does OEM/ODM customization take from kickoff to first article?
Answer: 29 days on the workflow described above, including schematic, PCB layout, BSP porting, sample fabrication and customer evaluation. Mass production starts around day 95.
Should I choose RK3576 or RK3568 for a POS terminal?
Answer: RK3576 for dual-screen lanes, AI item recognition, face payment and anything that wants a 6 TOPS NPU; RK3568 for restaurant and QSR counters, single-screen tills, payment terminals and mid-range lane builds; RK3566 for handheld, table-side and cost-driven single-screen tiers; RK3288 for legacy dual-screen replacements. AndroidSBC builds all of them on the same enclosure cut-out.
Can the lane keep taking payments when the network drops?
Answer: Yes. A local price book plus an offline authorisation store keeps the lane selling through a WAN outage, then reconciles when the link returns, with no lane lockout.
Can one board drive the cashier screen and a customer-facing advertising loop?
Answer: Yes. Two independent framebuffers give per-panel resolution, refresh and rotation, so the promotion half keeps running while the till half updates, with per-panel proof-of-play logs.
Can the board drive the cash drawer and the receipt printer directly?
Answer: Yes. RJ11 and RJ12 drawer rails are driven from the main carrier at 12V or 24V with a draw feedback line, and the receipt printer sits on an isolated rail with soft-start sequencing.
Do you support EMV and PCI PTS pre-scoping?
Answer: Yes. Discrete secure element, physical tamper lines with a zeroisation path, isolated PIN path and per-serial component traceability are all available, and EMC and payment pre-scanning is done in-house before third-party testing.
Do you support AI item recognition on-device?
Answer: Yes. The RK3576 runs a local model store on its 6 TOPS NPU with no cloud round-trip, typically clearing produce recognition in under 400 ms, with a low-light and steam-tolerant ISP profile.
What certifications can you pre-scope for our market?
Answer: CE / FCC / RoHS standard. UL / UKCA / KC / PSE / SAA, CB, IEC 62368-1, EMV, PCI PTS and GMS / Google EDLA are all available on request. EMC pre-scanning is done in-house before third-party testing.
Do you accept sample and small-batch orders?
Answer: Yes. Samples ship in 1-3 days from stock where available; custom samples ship inside the 15-18 day window. Small-batch and large-volume pricing is available on request, FOB Shenzhen, CIF or EXW.
