Crowtail Shield for Pico RP2040 Plug-and-Play
Elecrow Crowtail Expansion Shield for Raspberry Pi Pico (RP2040) Plug-and-Play
The Elecrow Crowtail Expansion Shield lets you connect plug-and-play Crowtail sensor and actuator modules directly to a Raspberry Pi Pico. No breadboard or soldering is needed for rapid prototyping. This shield breaks out all Pico GPIO pins into easy-to-use 4-pin connectors, making it ideal for schools, makers, and quick sensor experiments.

Compatibility
The shield stacks directly onto the 40-pin header of a standard Raspberry Pi Pico or Pico W. It works with all Crowtail modules that operate at 3.3V logic – over 30 sensor, display, and actuator boards. The pin mapping follows the Pico GPIO layout; I2C, SPI, and UART ports are clearly labelled on the silkscreen.
Wiring Notes
Plug the Pico into the shield’s female header and secure with the included screws. Connect Crowtail modules via the supplied 4-pin cables. Each digital pin can source up to 8 mA safely; avoid exceeding 25 mA total per port group. Power hungry modules should use an external supply.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Raspberry Pi Pico W?
Yes, the shield works identically with the Pico W because both boards share the same pinout and 3.3V logic. Wireless functionality remains unaffected.
Can I use this shield with other microcontroller boards?
No, this shield is designed specifically for the Raspberry Pi Pico’s 40-pin header and 3.3V levels. It will not fit or function safely with Arduino or other boards that use 5V logic.
Do I need to solder anything?
No soldering is required. The shield plugs directly onto the Pico, and Crowtail modules connect with snap-in cables.
