The module complies with European wireless communication hardware testing standards. The size is only 13.7×25.4×3.3mm, which is convenient for users to integrate into user equipment. Support wireless M-Bus protocol S, T, R2, C working mode, can work in slave, maser, repeater mode, can work in sleep mode with very low power consumption, and wake up through the serial port. When using, as long as the board is attached to the user board, it can be used through a simple communication interface protocol, which is simple and convenient.
