FCCA PSU Adapter
The FCCA PSU is a dual output power supply with adjustable output voltages between 1v~5v and can deliver a total of 3A. When connected to the FlashcatUSB it automatically detects and outputs the correct voltage. Alternatively the buttons can be used to manually set the output voltage. It has a USB Type-C connector which allows it to use USB power delivery in order to draw 3A at 5v from supported sources. Otherwise it's limited to 2A when using a regular USB to USB Type-C cable. It can also be powered through the 5v input.
Once you press either of the '+' buttons the PSU exits its auto mode for that channel and won't re-enter auto mode until you unplug the PSU. You can either press or hold down the buttons to adjust the output voltage.
When used with the FlashcatUSB I recommend connecting the FlashcatUSB, clip adapter, and PSU together first. Then plugging the USB Type-C cable into the power supply, and then plugging the USB cable into FlashcatUSB. Do the reverse when you're disconnecting everything.
When used on its own (not connected to the FlashcatUSB) the PSU might flutter around before you press a button since the ADC pins will all be floating.
