3.5 Direct USB
For USB applications, there is a directly connected USB port designated
TRGT_USB exposed as a Micro-B jack (Figure 16).
The USB lines are also routed to the header CN7-USB.
3.6 USB to UART connector
This connector, designated CMD_USB and exposed as a Micro-B jack (Figure
17), allows to access from a PC to the SERCOM0 (UART) of the module through
a virtual serial port over USB (FTDI USB-to-Serial UART converter). The UART to
USB conversion implements a full UART with hardware flow control (TX, RX,
RTS, CTS). Those UART lines are also routed to the header CN1-SERCOM-0.
