2.5 USB and Graphic User Interface (GUI)
One of the two FTDI2232 channels has been configured for implementing a serial
communication between PC USB and microcontroller UART, both for serial booting or for
controlling the microcontroller using a dedicated GUI.
The USB section (serial communication) is electrical insulated with respect to all the circuitry
adding opto-couplers in series to the path of TX and SX signals (see Figure 9: GUI: TX and
RX signals with optocoupler).

1. J20 connect the GND of the board to the GND of the USB input. This jumper should be removed when the
USB section must be electrically insulated

3. If S2 is present and the 12 V supply comes from the daughters boards, J16 must be left unconnected (no
external PSU must be powered and connected).
