car receiver module

KST-RX903 Wireless Supergeneration receiver module KST-RX903 is wireless data transmit and receive module with VHF/UHF super high frequency. adopting LSI circuit with hi-frequency and low-noise which import from famous company of Europe ,it has strong anti-static protection and high reliability. And it is your first choice among the distant transmit products as wireless remote control (rolling code), electric gate control system and the like. ion . A.

Application: 1 .Garage door control, automation control 2. home use security , 3 .GSM/GPS security system 4. Industrial control, communication and security system C. Picture: D. Characteristic 1.Low power receiver module 2.long distance receiver module 3.AM/OOK modulation 4.Low rate performance receiver module 5. Past FCC/CE certification 6.Low current receiver module 7.High security receiver module E. Notes : 1.The Antenna is using soft wire or other hard metal(like trolley antenna),The length is can’t be too long and too short, Otherwise it will interference the receive distance. If it uses the soft wire, please use it by straight , avoid to near the metal things. 2.The requirement on power and voltage is stability and low ripple coefficient . should be multi-stage filter (as add Beads, Inductance, Capacitance and so on) 3.Suggested MCU clock frequency should below 4MHZ if it uses with Single machine, otherwise the high harmonic crystal will influence on communication distance.
