Dual Supply for Raspberry Pi 4/5*.

Power your Raspberry Pi 4/5* from two 5V@3A (15W) USB-C power supplies. The ideal diodes automatically switch between input supplies if one fails or load share between them when both are available (using the droop method). The combined power is then output on a USB-C socket which is connected to the Raspberry Pi using a short USB-C <> USB-C cable (not supplied). The USB 2 data which is available on the Raspberry Pi 4 USB-C power port is broken out on the Micro USB connector.

The board is designed to fit underneath a Raspberry Pi 4/5, connected to the Raspberry Pi 4/5 using a short USB-C to USB-C cable.

Connectors

On the short edge there are 2 USB-C PWR IN A/B ports (5V@3A 15W Max). Each port has a red LED which indicates it is receiving power from the power supply and a green LED which indicates power is currently being sourced from this supply.

The short edge also has a Micro USB DATA port which is connected to the USB 2 data on the Raspberry Pi 4/5 USB-C port. By default power is not output on this port making it ideal to use as a USB device/gadget (PiKVM for example) to connect to another computer. To use as a USB host (to connect additional USB devices to your Pi) you will need to fit the 0.1" Jumper (not supplied) for it to output 5V on Micro USB socket.

The long edge has a single USB-C (PWR OUT/DATA) connector which should be connected using a short USB-C cable (not supplied) to the Raspberry Pi 4/5.

The PCB is supplied with

• 4* Stick on feet.
• 4* Spacer M-F.
• 4* M2.5 nut.
• 4x M2.5 6mm screw.

Additionally requires

• 1 or 2 USB-C Power Supply (5V / 3A / 15W)
• Short USB-C to USB-C >=3A capable cable
• Raspberry Pi 4/5, etc.

Please Note

• * Raspberry Pi 5 compatibility is based on publicly available information. Output power is 15W 5V@3A which will limit the power output on the Pi 5 USB3 Type-A sockets to 600mA.
• PCB and LED color may vary.
• Length of supplied M-F spacer may vary.
