From the project

The USB Power Injector allows a convenient way to power up USB 2.0 devices from a lab power supply, while still allowing data transfer from the device to the host.

The USB Power Injector allows a convenient way to power up USB 2.0 devices from a lab power supply, while still allowing data transfer from the device to the host.

When powering devices from a standard USB 2.0 port, either from a PC or from a standard USB hub, you never have the niceties that an adjustable lab style power supply has. During development that means you can’t set precise voltage and current limits. In the best case scenario, that means you can’t test under/over voltage protections. In the worst case, you run excessive current trough your device and you don’t even know that’s…
