Adafruit Terminal PiCowbell for Pico - Reset Button & STEMMA QT

Adafruit Terminal PiCowbell for Pico - Reset Button & STEMMA QT

3 units available with a short lead time.

Express post shipping available (product has a short lead time)

The Adafruit Terminal PiCowbell gives your Raspberry Pi Pico or Pico W quick, solderless access to every GPIO pin via screw terminal blocks. Simply connect 18–26 AWG solid or stranded core wires to any of the 40 terminal blocks — one for each pin on the Pico — making it perfect for prototyping and permanent installations alike.

The board also includes a right-angle reset button, a STEMMA QT / Qwiic connector for I2C devices, a central prototyping area with 15 rows of connected strips, and duplicate hole pads next to every Pico pin for solder-jumpering. Gold-plated pads throughout ensure easy, reliable soldering.

Key Features

  • 40 Screw Terminal Blocks – One for each Pico pad, using four 10-pin 2.54mm pitch terminal blocks for 18–26 AWG wire
  • Right-Angle Reset Button – Conveniently positioned at the board edge for easy access
  • STEMMA QT / Qwiic Connector – Right-angle JST SH connector wired to 3V, GND, IO4 (SDA), and IO5 (SCL), with extra breakout holes for additional I2C connections or reassignment
  • Mini Prototyping Area – 15 rows of 8-hole connected strips in the centre, usable like a mini breadboard (traces can be cut if needed)
  • Duplicate Hole Pads – Every Pico pad has a neighbouring hole for solder-jumpering
  • Ground and Power Strips – Ground pads marked with white silkscreen rectangles, plus dedicated long strips for ground and 3.3V power
  • Gold-Plated Pads – Easy, reliable soldering throughout the board
Note: This PiCowbell does not include socket or pin headers. There are several configuration options depending on how you want to mount your Pico:
  • Stacking headers – For plugging into a breadboard or other accessories with sockets
  • Socket headers – For a solid, direct connection without protruding pins
  • Short socket headers – For a slim, low-profile design (pair with short plug headers on the Pico)
  • Direct soldering – The most compact option, though the PiCowbell won't be removable
Tip: No I2C pull-ups are included on the board — most STEMMA QT / Qwiic breakouts already have them onboard. If using the Philhower Arduino core, Wire is pre-configured for IO4 and IO5. For CircuitPython or MicroPython, set SDA to pin 4 and SCL to pin 5.

Ideal For

  • Permanent wired installations with the Raspberry Pi Pico or Pico W
  • Prototyping with solid or stranded core wire connections
  • I2C sensor chains via STEMMA QT / Qwiic
  • Projects requiring easy wire-to-GPIO access without soldering directly to the Pico
