Access controller
Access controller is an open source ESP32 PCB design by physiii: a 4-layer, 150 × 90 mm board with 186 components (54 distinct parts). It is built around the MCP23017-E/SO, AMS1117-3.3, MIC29302WU-TR, TLP291-4(GB-TP,E(T and more. Filed under iot & wireless.
ESP32 lock controller with NFC and motion detection.
ESP32-S3 firmware, web controls and hardware for a two-channel strike/magnetic lock controller. Wiegand readers, keypads, exit buttons, fobs and motion inputs feed the same authorization and lock-control services.
Use the configured ESP-IDF checkout and espwebsocketclient component. The current firmware targets ESP32-S3; building does not flash a controller.
The browser check uses intercepted fixtures and cannot operate a real lock. It covers desktop/mobile navigation, AP/STA links and recovery after saving Wi-Fi settings. Omit CHROMIUMPATH` to use Playwright's installed Chromium.
