M0
Input
M1M0 The four working modes of the module are determined by the joint
combination. When in use, a 1K protection resistor shall be connected in series
externally, and a 1M pull-up resistor shall be added (it shall not be suspended,
otherwise, it can be grounded).

ACK
Output
The user indicates the data transmission result of the module, which is pulled down
before transmission and pulled up after success. It can be configured as drain open
circuit output or push-pull output. When it is used, a 1K protection resistor should be
connected externally in series (it can be suspended).
