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 simple I2C humidity sensor plus only required pull-ups/decoupling/power connections, wire it, then run checks and fix any issues.
The sensor circuit is wired. Review found only unused Pico header pins floating plus VBUS not used on this minimal shield, so I’m marking those intentionally unconnected and re-checking.
VBUS is modeled as a required power input, so I’m adding one simple 2-pin 5V/GND power header rather than adding USB-C circuitry. This keeps the shield minimal and gives the Pico a defined power source in the schematic.
