How to Use:
Recommend to buy more than 2 pieces:
1. For 2PCS, module 1 and module 2 send data to each other.
2. For >=3PCS, one as master device, the other as slave device.

The way they work is the same as wired RS485 bus: Master device transmit data, slave devices can all receive data, any slave device transmit data, master device and the other slave devices can receive.(When ever only allowed one device, master or slave, to transmit data)
