[Introduction]：This module is a wireless transceiver module based on AX5243 from AXSEM(can be transmitter and receiver).The module uses narrow-band transmission with 2W tranmitting power,which makes the transmission distance 2 times more than ordinary equivalent module. E31-433T33D can be compatible with other E31 modules.
