Raspberry Pi Pico IO Shield Expansion Board For Raspberry Pi Pico Development Board DIY Kit Electronic Projects
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.

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)
PIN35: ADC_VREF(ADC)
PIN33: AGND(analog)
PIN30: RUN(boot/forbid Pico)
