{"title":"Adafruit PiCowbell Proto for Pico - Reset Button & STEMMA QT","handle":"adafruit-picowbell-proto-for-pico-reset-button-stemma-qt","url":"/products/adafruit-picowbell-proto-for-pico-reset-button-stemma-qt","description":"The Adafruit PiCowbell Proto is a prototyping add-on board for the Raspberry Pi Pico and Pico W. It matches the Pico's footprint and sockets underneath, giving you a reset button, a STEMMA QT / Qwiic I2C connector, and a grid of prototyping pads — everything you need to quickly wire up custom circuits alongside your Pico.\n\nThe centre of the board features 13 rows of 4-hole connected strips that work like a mini breadboard, plus dedicated power rails for 3.3V and ground. Every Pico pad has a duplicate hole next to it for easy solder-jumpering to your prototype circuit.\n\nKey Features\n\n\nReset Button – Right-angle button that sticks out the end for easy access\n\nSTEMMA QT / Qwiic Connector – Right-angle JST SH for I2C devices on GPIO 4 (SDA) and GPIO 5 (SCL), with 4 extra breakout holes for re-assignment or additional I2C connections\n\n13 Rows of 4-Hole Connected Strips – Mini breadboard-style prototyping area in the centre; traces can be cut between holes if needed\n\nDedicated Power Rails – One long 3.3V strip and a ground strip near the reset button\n\nDuplicate Hole Pads – Every Pico pin has a matching solder-jumper hole; ground pads marked with white silkscreen\n\nGold-Plated Pads – For easy, reliable soldering\n\nPico-Sized Form Factor – Sits directly underneath the Pico for a compact stack\n\n\nHeader Options\nThis PiCowbell does not include headers to keep things flexible. Several configurations are available:\n\n\nStacking Headers – Plug into a breadboard or other accessories with sockets\n\nSocket Headers – Plug the Pico directly in for a solid, compact connection\n\nShort Socket Headers – Ultra-slim pluggable design; pair with Short Plug Headers on the Pico for a skinny sandwich\n\nDirect Soldering – Most compact and inexpensive, but permanent\n\n\nI2C Configuration\n\n\nArduino (Philhower core) – Wire peripheral is pre-configured for GPIO 4 and 5\n\nCircuitPython / MicroPython – Set SDA=4 and SCL=5 in your code\n\n\n\nTip: No I2C pull-up resistors are included on the board, but most STEMMA QT / Qwiic breakouts have them built in.\n\n\nIdeal For\n\nCustom circuit prototyping with Raspberry Pi Pico or Pico W\nAdding I2C sensors and breakouts via STEMMA QT\nQuick breadboard-free builds and one-off projects\nCompact wearable or embedded prototypes\n\n\nPackage Contents\n\n1× Adafruit PiCowbell Proto PCB (assembled with reset button and STEMMA QT connector)\n\n\n\nNote: Raspberry Pi Pico and headers are sold separately. Mount the Pico on top if you want the BOOTSEL button and LED accessible.\n","vendor":"Adafruit","product_type":"","in_stock":true,"options":[],"variants":[{"id":1332,"title":"Default Title","sku":"AF-5200","price":4.2,"on_sale":false,"in_stock":true,"available_quantity":53,"option1":"Default Title"}]}
