Detailed

RF7129 is a highly integrated ultra-low-power half-duplex micro-power wireless data transmission module, embedded in a high-speed single-chip and high-performance RF chip the A7129. The efficient circulation innovative interleaved error correction coding, anti-interference and sensitivity are greatly improved A7129 module provides a choice of multiple channels can be modified online serial rate, transmit power, RF rate and other parameters.

 
RF7129 can work in the voltage range of 4.5-5.5v and consumes only 3.2mA in receive state has four operating modes. , Receiving only consumes less than 20uA, a 3.6V/3.6A lithium batteries work for more than 10 years in power saving mode.
