* Due to the size limitation, there's no 5V output from the
FC to the USB-C module, so you need to power the AIO with
a battery before you connect the AIO flight controller to your
computer with a USB-C cable.

Note: In order to prevent the AIO from being burnt out instantaneous
voltage spikes on powering up, it is strongly recommended to use the
Low ESR capacitor in the package.
