Prototype Breakout Board Green Cell Proto Tripler PiCowbell for Raspberry Pi Pico/Pico W with STEMMA QT/Qwiic Compatibility

Proto Tripler PiCowbell by Green Cell is a prototype breakout board made for Raspberry Pi Pico and Pico W. It exposes the Pico's GPIO pins to easily accessible pads and headers, and features three separate prototype areas for soldering components or creating custom circuits. The board includes connectors compatible with STEMMA QT and Qwiic ecosystems, enabling straightforward connection of compatible sensors and modules without additional wiring. The compact design keeps essential signals routed for general-purpose prototyping and IoT experiments.

Advantages

The breakout board simplifies access to the Raspberry Pi Pico and Pico W pinout, reducing the need for breadboards and extensive jumper wiring. Three dedicated prototyping zones allow parallel development of circuits or simultaneous testing of multiple modules. STEMMA QT and Qwiic compatibility provides plug-and-play connectivity with a wide range of I2C sensors and peripherals. The board's layout groups power, ground and common signal lines for cleaner wiring and easier troubleshooting.

Suitable for

• Rapid prototyping of microcontroller projects using Raspberry Pi Pico or Pico W
• Educational electronics labs and student projects
• IoT sensor integration and small-scale testing
• Custom peripherals and circuit experiments requiring multiple prototype areas

Key specifications

• Compatibility: Compatible with Raspberry Pi Pico and Raspberry Pi Pico W form factor and pinout
• Prototype areas: Three separate prototyping zones for soldering components and creating circuits
• Connectivity: On-board STEMMA QT and Qwiic-compatible connectors for I2C modules
• GPIO access: Exposed GPIO pads and header footprints matching Pico pin assignments
• Power handling: Standard 3.3V power routing as used by Raspberry Pi Pico boards
• Form factor: Compact breakout board sized to align with Pico module placement

How to use

Place a Raspberry Pi Pico or Pico W into the breakout board header or solder it according to the board's recommended mounting method. Use the exposed GPIO pads and header pins to connect sensors, actuators, and peripherals. Solder components into the three prototype areas to build custom circuits or wire small modules directly to the board. Connect STEMMA QT or Qwiic-compatible sensors by plugging into the corresponding connectors for quick I2C communication setup. Ensure power polarity and voltage levels match the Pico's 3.3V requirements before applying power.

Usage recommendations

For reliable results, use short, well-routed jumper wires when interfacing external modules and keep power and ground traces tidy to minimize noise. When testing wireless functions on the Pico W, maintain distance from large metal objects and ensure antennas are unobstructed. Confirm pin mappings in your project code against the Pico pinout and the breakout board's silk-screen labels before soldering irreversible connections.
