A base board that a 30-pin ESP32 dev board drops into, bringing every GPIO out as a group with power and ground beside it so sensors and servos plug in with a 3-wire lead. There are three ways to power it - USB-C, micro-USB or a 5.5 mm DC jack - an AMS1117 regulator on board, a jumper to choose whether the header rails carry 3.3V or 5V, and a dedicated 4-pin I2C header (GND, VCC, D21, D22). Turns a bare ESP32 into something you can wire up properly.
Key features
- Takes a 30-pin ESP32 dev board (DevKit V1 style), not included
- GPIOs broken out with power and ground alongside each pin
- Jumper selects 3.3V or 5V on the header power rails
- USB-C, micro-USB and 5.5 mm DC jack power inputs
- AMS1117 regulator and a power LED on board
- Dedicated 4-pin I2C header: GND, VCC, D21, D22
