Solder-free proto plate for Raspberry Pi Pico/Pico H, adding a reset button and a STEMMA QT / Qwiic I2C connector. Mounts under the Pico on a breadboard. Requires Pico H or Pico WH for plug-and-play use; standard Pico needs header soldering.
Main Raspberry Pi Pico socket interface; plug in a Pico and access each Pico pin through an extra row of sockets.
3V supply on the right-angle JST-SH STEMMA QT/Qwiic connector.
Ground on the right-angle JST-SH STEMMA QT/Qwiic connector.
I2C data on the STEMMA QT/Qwiic connector, mapped by Adafruit to Pico IO4.
I2C clock on the STEMMA QT/Qwiic connector, mapped by Adafruit to Pico IO5.
Extra set of four breakout holes next to the JST-SH connector for additional I2C connections or reassignment.
Right-angle reset button that sticks out from the end of the board.
Long strip of connected holes for 3.3V power.
Ground pads and long ground strip identified by Adafruit near the reset button.
Three hole-connected strips in the centre area, intended as a mini solderless proto area with cuttable traces.
