3 Debug Interface
The debug interface is described in the following sections.
3.1 UART–J3408
Figure 4: UART–J3408
To access the UART console interface, connect the TTL to UART transceiver module as shown in
(such as the
RS232 To TTL converter module serial module DB9 connector). Do not use a USB-to-TTL cable to connect to the board
directly. It may cause chip damage due to incorrect power rail or surge issues.

NOTE:
The baud rate of the UART is 9600.
