USB UART module
The USB UART module is used to connect the microcontrol-
ler to an external USB device. To establish connection be-
tween the microcontroller and the USB UART module, it is
important to set switches 1 and 3 (optionally 2 and 4) to the
ON position.
The BIG8051 can also use this module to power itself. To
achieve this, it is necessary to set the switch position of jumper
J11 (found on the power module) from EXT to USB.
