RF modules: Transmission of a signal through a carrier frequency (RF = radio frequency). CPCA = Carrier-Present Carrier-Absent 0- minimum amplitude 1-maximum amplitude Transmission rate: Up to 5000 bits per second Transmission range: Up to 300 feet Costs: - Transmitter costs about 18 - Receiver costs about 41 - Antenna costs about 10

Transmitter Reduced to 4 pins Antenna/wire Data Ground VCC Ladj/gnd

Receiver Data PDN Vcc Ground Reduced to 4 pins NC = No Connection, for physical support only PDN = Power Down

Parameters Transmitter Receiver

Operating transmitter at 5V Operating receiver from 4.7- 5.2V For the transmitter, if power supply is not clean (noise less than 20mV) Operating transmitter at 5V Operating receiver from 4.7- 5.2V Put 430 Ohm resistor in series with the LADJ/GND Put 200 Ohm resistor in series with the Vcc MANUALS: http://www.linxtechnologies.com/interface.php?section=products&category=rf_modules&subcategory=lc_series
