Raspberry Pi Pico 2 Design

A

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 in this run.
Nothing has been added yet. The project is still empty: 0 components and 0 nets.
Recommended minimal design to implement next:
  • Raspberry Pi Pico 2 shield headers matching the Pico 2 pinout.
  • One I2C humidity sensor, preferably a simple 3.3 V device such as SHTC3/SHT31-class.
  • I2C pull-ups on SDA/SCL to 3V3, typically 4.7 kΩ unless the sensor datasheet recommends otherwise.
  • Local decoupling for the humidity sensor, typically 100 nF close to VDD/GND per datasheet.
  • Use the Pico 2’s onboard 3V3 rail for the sensor to avoid adding a regulator unless external power is required.
  • Optional but useful: labeled test points or net labels for 3V3, GND, SDA, and SCL.
What remains:
  1. Confirm the exact Pico 2 shield header footprint/pin mapping.
  2. Select the humidity sensor from the available component library.
  3. Check the Pico 2 and sensor datasheets before wiring.
  4. Add and wire headers, sensor, pull-ups, and decoupling.
  5. Run schematic review/ERC and fix any issues before moving to layout.
