Description

D1 mini ESP32 grove shield

This is a base shield that lets you use the D1 mini ESP32 board with the Grove system connectors for fast and easy prototyping. Two sockets are connected to the default I2C pins. Use 2x10 row pass-through pin headers (like these) for access to all pins with dupont wires.

The switch sets the VCC of the grove connectors to either 3.3V or 5V

Links to parts:

Switch: Any three pin SPDT on-on switch will do. I suggest SLW-883935-2A-D . Alternatively just solder a bridge between center pin and either voltage pin.

Grove sockets: https://a.aliexpress.com/_Ez26KX2 (get 5 of the "straight needle" variant and 2 of the "bent needle" variant per board)
