2 Module interfaces
Pin number Symbol Pin type Function
6 RXD2 I/O Serial port
UART2_RX, which
can also be used a
common I/O pin
and corresponds
to P0 of the IC chip
7 TXD2 I/O Serial port
UART2_TX, which
can also be used a
common I/O pin
and corresponds
to P2 of the IC
chip. It can used
to output logs.

interface, which
can be used as
PWM output of the
LED drive and
corresponds to
P26 of the IC chip
9 P31 I/O Common I/O
interface, which
can be used as
PWM output of the
LED drive and
corresponds to
P31 of the IC chip
