Description
The Raspberry Pico IO shield is designed for the Raspberry Pi Pico development board, without soldering. It also incorporates communications ports like 2 x I2C, 2 x UART, 2 x SPI, 3 x analog IO and 13 x digital IO as well as a 6.5-12V power interface. The integrated Lego position holes can assist to wire up multiple sensors or modules, which exceedingly increase more functions
