[Introduction]：E64-433T20S is applicable for star network with low power consumption. The biggest feature is to support at most 31 slaves send data to master at the same time and WOR mode for slaves(the average current is below 30uA). Data reliability and accuracy are guaranteed by strict data parity and automatic retransmission mechanism between master and slave.
