Application matrix: 8 customization scenarios for the AS-RK3566-HHP-CUS
The AS-RK3566-HHP-CUS is one carrier platform across eight different POS deployments. The matrix below shows the most common OEM/ODM customization angles a self-checkout equipment buyer in Southeast Asia walks through in the first scoping call.
Frequently asked questions
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 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.
