Minimal Pico 2 Setup

amirkat

Add the minimum required components needed for this Pi Pico 2 to function properly. Keep the design as simple and minimal as possible.
You may include a single humidity sensor as the primary peripheral, along with any essential supporting components such as power regulation, pull-up resistors, decoupling capacitors, or required connectors.

I’ll keep this minimal: inspect the Pico 2 shield pins, select one low-power I2C humidity sensor, add only the required pull-ups/decoupling, wire it to the Pico 2 3V3/GND/I2C pins, then run checks and fix real issues.

Thought for a moment

Done — I added a minimal SHTC3 humidity/temperature sensor block: U2 SHTC3, C1 100 nF decoupling, and R1/R2 10 kΩ I2C pull-ups on Pico GPIO4/GPIO5, powered from the Pico 2 3V3 rail.
Focused schematic ERC is clean. The only remaining full-review errors are PCB airwires because the new parts have not been placed/routed yet; that’s expected until you approve moving into layout.
I also created Minimal Pico 2 Humidity Sensor Design Notes with the datasheet rationale, connections, BOM choices, and validation status.

Raspberry Pi Pico 2 Shield Template sewE

Raspberry Pi Pico 2 Shield Template sewE thumbnail
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.
To learn more about what's the key differences between the original Pi Pico and the new Pi Pico 2, read our blog https://www.flux.ai/p/blog/whats-new-in-the-raspberry-pi-pico-2-a-showdown-with-the-original-raspberry-pi-pico
