Pinout
We don't publish a pin table for this part: no official source we could verify gives one. Check the labels printed on your module, and see the notes below.
Captive USB-C cable; no pin table is published.
Build with it
Project ideas for the Raspberry Pi 4 USB-C power supply. Each link opens Soldr with the prompt filled in; Soldr assigns the pins, checks power and shows how to wire every part.
- Raspberry Pi 4 home dashboard: The supply is made for the Pi 4 and gives 5.1 V at 3.0 A nominal. Plug it into a wall socket only; do not open it or touch its mains side.
- Pi 4 time-lapse camera: A steady supply matters for unattended runs. Point the camera at plants, not at people; if it can see people, tell them and get their consent first.
- Pi 4 temperature logger: The probe uses the Pi's 3.3 V and a 1-Wire GPIO pin. The supply stays at the wall; only the low-voltage USB-C side goes to the Pi. Learning project.
Common mistakes
- This is a mains-powered unit: do not open it, modify it or wire anything to its mains side; plug it into a wall socket and connect only the USB-C plug to the Pi (source: link, Input specification, p.3)
- Using a weaker charger: the supply is rated 5.1 V at 3.0 A nominal for the Raspberry Pi 4 and Raspberry Pi 400 (source: link, Output specification, p.3)
- Using it in a hot enclosure: operating ambient temperature is 0-40 C (source: link, Environment, p.4)
Not covered by the official source
