4. Connect to MCU

No.

Brief description of the connection between the module and the MCU (the above figure uses the STM8L MCU

as an example)

1

The UART module is TTL level, please connect with TTL level MCU.

2

For some MCU works at 5VDC, it may need to add 4-10K pull-up resistor for the TXD & AUX pin.

5. Operating mode

There are four operating modes, which are set by M1 and M0, the details are as follows:

Mode(0-3)

M1
