Minimal Pi Pico 2 Setup

flux

I’ll keep this minimal: inspect the Pico 2 shield pins, select a simple I2C humidity sensor, add only its required decoupling and I2C pull-ups, wire it to the Pico 2’s 3V3/GND/I2C pins, then run review and fix any schematic issues.

I selected the SHTC3: it runs directly from the Pico 2 3V3 rail and only needs a 100 nF local decoupling capacitor plus one pair of I2C pull-ups.

The added sensor circuit is wired correctly. Review is now only flagging unused Pico header pins, so I’m tying the remaining Pico ground pins to GND and marking intentionally unused header pins as no-connect for this minimal shield.

Done — I added a minimal SHTC3 humidity/temperature sensor circuit for the Pico 2 shield: U2, 100 nF decoupling, and 10 kΩ I2C pull-ups on GPIO0/GPIO1. Power/GND/I2C wiring is complete, unused Pico shield pins are intentionally marked no-connect, and the ERC checks now report no unresolved issues.
Next step is PCB layout/placement if you want to continue.
Yes, start layout
Keep sensor near edge
Add mounting holes
Check BOM cost
Use different pins

    This is the project template for the Raspberry Pi Pico 2, the latest addition and update to Pi Pico line up.
    Raspberry pi pico 2 is equipped with the RP2350, a cutting-edge, high-performance microcontroller designed with enhanced security and versatility in mind. Every element of its design has been upgraded, from the advanced CPU cores to the innovative PIO (Programmable I/O) interfacing subsystem.
    The Raspberry Pi Foundation has integrated a robust security architecture centered around Arm TrustZone for Cortex-M, ensuring data protection and integrity. Additionally, new low-power states and expanded package options broaden the range of applications, making the Pico 2 an ideal choice for diverse, power-sensitive projects.
