Overview
PLC V1.1 keeps the proven PLC V1 core I/O behavior while adding board-level polish around programming, power, and expansion. It uses an ESP32-WROOM-32E-H4, CP2102N USB-to-UART, PCA9306 level shifting for the 5V I2C accessory header, 10 opto-isolated digital inputs, 8 onboard relays, and AO1 from ESP32 DAC1 on GPIO26.
Highlights
- Same core PLC V1 I/O behavior with V1.1 board-level refinements
- Two I2C accessory headers: one 3.3V header and one 5V header
- PCA9306 level shifting for the 5V I2C accessory header
- CP2102N USB-to-UART for programming and serial monitor
- 10 opto-isolated digital inputs, 8 onboard relays, and AO1 on GPIO26
