Micro-USB Data/Power Splitter

This adaptor allows the Raspberry Pi to be used with an official Raspberry Pi 3 Micro-USB power supply (or 5V DC barrel jack) whilst allowing access to USB OTG data over a separate micro-USB connection. The barrel jack accepts 5.5 mm plugs (2.1/2.5 pin) supplying 5V.

USB Type-A (data and power) <> USB Data (Micro USB) and Power (Micro USB/Barrel jack).

We also have a USB Type-C version of this adaptor available.

Using with the Raspberry Pi 4

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

• A short USB-C to USB-A cable between Pi4 and the adaptor board
• Micro USB cable to access USB OTG Data.
• Power via either Micro USB Power Supply or Barrel jack (5v 2.4 Amp or higher PSU).

(Raspberry Pi/USB Cables/PSU/etc. not included)

Short cables are advised as the voltage drop over longer cables may cause problems.

Using a Cluster HAT node image (p1/p2/p3/p4) you can plug the USB data into a computer (Raspberry Pi, Win10, etc.) and access the system via either USB Gadget Ethernet or Serial Console.
