USB/PWR Splitter guide

1. Introduction

The adaptor allows the Raspberry Pi 4 to be used with a Pi USB-C power supply while allowing access to USB OTG data over a separate USB-C connection.

USB-C (RPI4) <> USB-C (USB) and USB-C (PWR)

To use the adaptor with the Raspberry Pi 4 you need.

• USB-C to USB-C cable[1] between Pi4 and the adaptor board
• USB-C to USB-C or Type-A between adaptor board and PC
• Power[2] via Official Raspberry Pi USB Type-C Power Supply.

[1] Whilst USB-C cables are generally designed for higher current I still advise using short power cable to the Pi where possible to reduce voltage drop.

[2] PLEASE NOTE With the Pu/Pd resistors on this board it can only be used with 5V supply to power a 5V device.

An adaptor of this kind does not fall within the USB specification. It's designed for use with the official Raspberry Pi USB-C power supply and raspberry pi, use with other power supplies/chargers and devices may cause issues/damage.
