HM-R v3.1 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 HM-R receiver module Pins name Note: ENABLE active hi make module work and low sleep the module. It is recommended than keep ENABLE low while power on, and then active it after module initialization Application Pin to pin replace the old ASK module pair. Special design can be made for more sophisticated application. Tel: +86-755-82973806 Fax: +86-755-82973550 E-mail: [email protected] http://www.hoperf.com Update:5/26/2008 HM-R v3.1 Specification 1.
