This very simple device allows you to inject power from an independent source - a lab power supply, battery, powerbank or solar panel - into a USB cable.

I originally made it for my (pending) programmable powerbank project, which both charges and communicates over USB. Unfortunately, most PCs only allow 500mA of current over the USB port. So if I wanted to charge my powerbank at full bore AND still communicate with the PC, I had to use my lab power supply for power while still keeping the D+/D- data lines connected. That's why I made this little PCB.

How to use

The board accepts three connections: A USB Micro-B input carrying the data signal, a pluggable screw terminal (very handy!) to supply the power and a USB type-A output that combines data and power to your device.

Be very careful when wiring power to the screw terminal! It only fits in one way, but you still have to screw in the power at the right polarity. Double-check with the silk-screened '5V' and 'GND' markings. Also make sure the input voltage is neither too low nor too high for your device - USB generally requires 4.5-5.5V on the power lines. Do something wrong here and you can blow up your USB device!

Excellent! What a great idea for a product.

Great response to my dumb questions.
Looking forward to getting these into my project

Rock on!

Very affordable gadgets

Exactly what I needed; allows me to provide 5V 2A to my prototype while at the same connecting data to my laptop. Also well made and inexpensive.
