D. Characteristic
1. ASK receiver module
2. non-noise wave , anti-motor and anti-disturb receiver module
3. Past FCC/CE certification
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.
