RFM83
RFM83 is ASK/OOK Super-heterodyne receiver module manufactured by HOPERF.
Description
RFM83 series module are low cost superheterodyne receiver module based on RF83 chip, working at frequency 315Mhz and 433.92Mhz(We can customize other frequency 300Mhz and 440Mhz). The operating voltage is 2.1V-3.6V(RFM83L) and 3.6V-5.5V(RFM83). The module can be widely applied to various types of data transmission system. It provides two additional functional pins: (1)Enable pin: allow the module to switch between work status and sleep status in order to reduce overall power consumption.(2)wake-up output: when RF signal input, it provides and output signs. （This datasheet only describes the basic functions and
Electrical Characteristics of the module. For more details , please refer to the RF83 chip datasheet .）
