Vending Machine Controllers: Choosing a Brain for the Box
A vending machine is “a cabinet that takes money” — the controller board decides how smart it is.
Controller requirements
- Slot control: GPIO/relay channels driving solenoids and motors;
- Payments: 4G + Ethernet dual-path with offline accounting and replay;
- Display: 10-21″ touch panel needing mid-range silicon for smooth UI;
- Vision add-on: verify successful pickup to prevent disputes — NPU territory.
Compute matching
Pure vending: RK3566/3528 class suffices. With visual fulfillment plus ad screens: RK3576. Capacitor aging is the industry’s classic board failure — industrial-grade components cut 5-year failure rates from ~8% to under 2%.
