V. Remarks

Antenna with a soft wire or other hard metal (like telescopic antenna), the length of neither too long nor too short, otherwise it will affect the receiving distance. If you use soft wire, please straighten use, and try not to close metal objects.

Supply voltage for stability and low ripple factor, to be multi-stage filter (such as increasing the bead capacitors, inductors).

When used with the recommended single-chip MCU clock frequency and the crystal in the following 4MHz possible from the RF receiver module, otherwise the higher harmonic crystal affects the communication distance.

Antenna length: 24cm (315MHz), 18cm (433.92MHz), we need the other frequency antenna length test, in order to achieve optimum reception
