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


  • Power supply: 5V

  • Digital IO x 13:GP2, GP3, GP12 ~ GP22
  • Analog IO x 3: GP26, GP27, GP28
  • UART x 2: UART0, UART1
  • I2C x 2: I2C0, I2C1
  • SPI x 2: SPI0, SPI1
  • Power interface: 6.5 - 12V
  • GPIO pins, are used for the RP2040 chip of the Pico development board, as shown below;
  • GPIO29: for ADC mode(ADC3) measure VSYS/3
  • GPIO25: connected to LEDs of users
  • GPIO24: VBUS sensing-if VBUS exists, it is the high level, in contrast, it is the ow level
  • GPIO23: on-board SMPS chip control pin
  • In addition to 26 GPIO pins(GP0~GP22, GP26_A0, GP27_A1, GP28_A2) and 7 GND pins, the Pico board has 7 physic pins as follows
  • PIN40: VBUS(5V)
  • PIN39: VSYS(2~5V)
  • PIN37: 3V3_EN(on-board SMPS chip Enable)
  • PIN36: 3V3(3.3V)
  • PIN33: AGND(analog)
  • PIN30: RUN(boot/forbid Pico)
