Add Raspberry Pi Pico 2 shield then add the minimum required components needed for it 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’m blocked because execution credits are unavailable, so I can’t modify the schematic or add parts in this run.
Nothing has been changed yet: the project is still empty with 0 components and 0 nets. The intended next work is to create a minimal Raspberry Pi Pico 2 shield schematic with:
Raspberry Pi Pico 2 shield headers / mating connector footprint
One humidity sensor peripheral, preferably I2C for simplicity
I2C pull-up resistors if not integrated on the sensor module
Required decoupling capacitors near the sensor and any power pins
Simple power distribution from the Pico 2 3V3 rail, avoiding extra regulation unless required
Clean labeled nets for 3V3, GND, SDA, and SCL
ERC/review pass after wiring
When credits are available, I can proceed by selecting datasheet-backed parts, wiring the minimal schematic, and validating it before any layout work.
