The Adafruit Terminal PiCowbell with Pre-Soldered Sockets gives your Raspberry Pi Pico or Pico W instant plug-and-play access to every GPIO pin via screw terminal blocks. Simply plug in your Pico and connect 18–26 AWG solid or stranded core wires to any of the 40 terminal blocks — one for each pin — making it perfect for prototyping and permanent wired installations.
Unlike the headerless version, this PiCowbell comes with single-row socket headers pre-soldered, so there's no soldering required to get started. The board also includes a right-angle reset button, a STEMMA QT / Qwiic connector for I2C devices, and a central prototyping area with connected strips.
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
- Pre-Soldered Socket Headers – Plug in your Pico or Pico W immediately with no soldering required
- 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 – 12 rows of 4-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 version comes with pre-soldered socket headers. While this makes setup instant, it means you cannot substitute short headers or stacking headers. If you need a different header configuration, consider the version without pre-soldered sockets.
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
- Quick plug-and-play setups with the Raspberry Pi Pico or Pico W
- Permanent wired installations using solid or stranded core wire
- I2C sensor chains via STEMMA QT / Qwiic
- Projects requiring easy wire-to-GPIO access without soldering 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 board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny 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.
- GND
- GND is the ground or reference connection (0 V) for a circuit. When connecting two devices together, their grounds must be joined so both agree on what counts as a low or high signal.
- 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 connector contacts on a fixed pitch (commonly 2.54 mm) used to link a board to a breadboard, jumper wires, or another board. They come as male pin headers and female socket headers; when a module ships with pre-soldered headers it can be used straight away, whereas bare pads require soldering 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.
