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

Jargon buster
Plain-language definitions for the technical terms used above.
- AWG
- American Wire Gauge is a numbering system for wire thickness, where a lower number means a thicker wire. The AWG rating matters because thicker wire can usually carry more current with less voltage drop and heating.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- CircuitPython
- A beginner-friendly version of Python designed to run directly on microcontroller boards. If a product supports CircuitPython, you can often program it by copying code files onto the board rather than setting up a more complex toolchain.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- Headers
- Rows of metal pins used to plug a module into a breadboard or connect it with jumper wires. Pre-soldered headers make the module easier to use straight away without needing to solder the pins yourself.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- MicroPython
- A version of the Python programming language made to run on microcontrollers. It matters because it lets beginners write readable code to control LEDs, sensors, motors and displays without needing to start with lower-level languages.
- Qwiic
- Qwiic is a plug-in connector system for I2C devices that uses small 4-pin cables, so you can connect compatible sensors without soldering. It matters because your controller or adapter also needs Qwiic, or you will need a cable or breakout to wire it up.
- STEMMA
- A plug-and-cable connection system used on some maker electronics boards to make wiring simpler. If a product uses STEMMA, you need the matching cable or connector type to plug it in without soldering.
- STEMMA QT
- A small plug-in connector system for I2C boards that lets you connect compatible sensors and controllers without soldering. It matters because it can make wiring faster and less error-prone, especially when adding several small modules to a project.
- UPS
- An uninterruptible power supply is a battery-backed power system that keeps a device running when external power is unplugged or fails. For an embedded computer, it helps prevent sudden shutdowns that can corrupt files or interrupt a project.
