Introduction
E64-DTU (433NW20) is suitable for low-power one-master-multi-slave star network. Its biggest feature is that it supports up to 31 slave data to be sent to the master at the same time, and supports the slave WOR working mode, with the lowest receiving power consumption of about 30uA. Strict data check and automatic retransmission mechanism between master and slave ensure data reliability and correctness.
