Brief Introduction

 

 

E64 series is applicable for star network at low power consumption. It supports a maximum of 31 slaves to send data to master at the 

same time and the slaves can work at WOR mode. (The average current is below 30uA).

 

Data reliability and accuracy are guaranteed by 

strict data parity and automatic re-transmission mechanism between masters and slaves. The module operates at 425-451.3MHz, with 
transmitting power at 100mA and command transmission available. The module communicates with MCU via UART interface. 

        E64 series can be either master or slave. When module works as master, it can monitor and receive data from slaves. And when module 
works as slave, it can be set to work at WOR mode or slave-transmitter mode. WOR mode allows master to send data and initiate slaves, 
while slave-transmitter mode only allows slave to send data to master initially.
