Changes

2.Some new features of X825 V2.0(Updated on April 1st 2021):

①Add 4 test pins to achieve powered between X825 V2.0 and Pi4 without additional cable. You can get power from the PI4's Type-C port or X825 V2.0 DC JACK power socket.

②Removed the on-board power button and external switch interface. You can connect the X735 board for power management.

③Reduced the height of the USB connector connecting X825 V2.0 and PI4, so the matching metal case '''X825-C8''' is shoter 12mm than X825-C6.
