4.13 SP12: UART-to-USB Bridge
The UART-to-USB bridge chip (FT230XS-R from FTDI) on the iMX OEM Carrier Board connects to
UART channel #1 on the i.MX RT1062. It exist to simplify connection to a PC because serial ports are
not so common any more, especially not on laptops. The USB port also offers the possibility to power
the board.
It is possible to disconnect the UART-to-USB bridge chip from UART channel #1 via JP3, for example
if the UART needs to be connected to another device.
There are two LEDs, transmit from the board (LED11) and receive to the board (LED10), that signal
communication activity.
See picture below for locating relevant components.
