Embedded payment control board
A modular control platform connecting payment input signals with credits, relay actions, and user feedback.
The project
Translate input from payment peripherals into a configurable machine-control workflow.
Product highlights
- Bill-acceptor pulse input and card-reader integration logic.
- USB communication with a Windows application.
- Digital credits, relay outputs, LED indicators, and audio feedback.
How we approached it
For a connected device like the Embedded payment control board, we start with the control logic that must always work, then add connectivity on top. The design, built on ESP32-S3, USB, keeps essential functions local, so the product still behaves safely if Wi-Fi or the app is unavailable.
Inputs, outputs and user feedback are mapped before firmware starts, and each interface is tested on real hardware rather than in simulation alone. Updates are planned with a rollback path, as described in our fail-safe OTA guide.
