Below is a suggestion for powering your Raspberry Pi 5 using a USB‑C female port. In essence, you want the following:
Power Lines:
Connect the USB‑C’s VBUS (5 V) pin to the Raspberry Pi’s 5 V rail
Tie the USB‑C GND pins to the common ground (using the Ground component)
CC Pin Configuration:
To ensure the Pi (as a power sink) is correctly identified by the source, add a 5.1 kΩ pull‑down resistor to one of the CC pins (typically CC1). This resistor signals that the port is a sink; if you’re not planning to include a full USB Power Delivery controller, this is a common and sufficient approach.
Additional Considerations:
Verify that the cathode protection or any reverse-polarity protection circuit is in place if needed.
Make sure your power supply via the USB‑C cable is rated for the required current (the Raspberry Pi 5 typically needs a robust 5 V supply, often around 3 A).
Let me know if you’d like suggested schematic changes (e.g., wiring the [J2] USB‑C connector’s VBUS, GND, and CC pin along with adding the 5.1 kΩ resistor) to be applied in your project.
