HM-R HM-R series FSK receiver module
General
HM-R series receiver module is specially designed by Hope Microelectronics Co., Ltd. For replacing those applications that used ASK technology module already. It used together with HM-T/HM-TP series FSK transmission module. Due to the benefits form FSK technology, the module is robust to interference, and longer working range can be achieved.
FEATURES 1. Highly integrated, small size 2. Hi sensitivity, low power consumption 3. FSK technology, suitable for replacing ASK modules 4. Less interference, longer working range 5. Can be used to replace ASK module pair W/O software modification 6. No manual tuning required during production
