## Summary description

Proto Under Plate for Raspberry Pi Pico by Green Cell is a prototype breakout plate designed to sit under a Raspberry Pi Pico to expose GPIO and STEMMA QT connections and provide a reset button. It enables convenient prototyping, wiring and integration of sensors or modules that use STEMMA QT, and simplifies access to Pico pins for development and testing.

## Long description

Proto Under Plate for Raspberry Pi Pico by Green Cell is a prototype breakout plate designed to be mounted beneath a Raspberry Pi Pico to expose GPIO pins and provide STEMMA QT connections together with a reset button. The board creates a convenient access point for wiring, sensor and module integration, and rapid development, while keeping the Pico form factor and pinout intact.
Advantages
The under plate presents Pico GPIO lines and a STEMMA QT connector in a compact layout that simplifies prototyping and reduces the need for soldering directly to the Pico. A built-in reset button allows quick resets during testing and development. The breakout traces and pin headers make it easier to attach jumper wires, breadboards, and compatible STEMMA QT accessories without modifying the Pico itself.
Suitable for
 Prototyping and development with Raspberry Pi Pico
 Connecting STEMMA QT sensors and modules
 Educational projects and workshops
 Testing GPIO-based peripherals and circuits
Key specifications
 Form factor: under-plate designed to fit Raspberry Pi Pico footprint
 Connectivity: exposed GPIO pins for header access
 STEMMA QT: dedicated connector for compatible I2C sensors and modules
 Reset: integrated push-button reset switch
 Mounting: supports stacking under the Pico for compact assembly
 Compatibility: designed for use with Raspberry Pi Pico development board
How to use
Position the Proto Under Plate beneath the Raspberry Pi Pico so that the Pico’s pins align with the under plate’s header pads or through-holes, then secure the boards together following the manufacturer’s mechanical guidance. Attach jumper wires, headers or STEMMA QT cables to the exposed connectors to route power, I2C, SPI, UART or individual GPIO signals. Use the reset button to restart the Pico during code uploads or troubleshooting. Ensure power and signal connections match the Pico pinout before applying supply voltage.
Usage recommendations
For reliable operation, use compatible STEMMA QT cables for sensor connections and verify pin alignment when stacking the Pico on the under plate. Avoid applying power while reconfiguring wiring; consult Pico documentation for voltage and GPIO limits to prevent damage.
