Prototyping Hints:
It is essential when building any Low Power Radio System that you have a ‘clean’ DC power source. Typically
the ripple voltage should be less than 10mV Peak to Peak. Normally a 470uF decoupling capacitor is sufficient
de-coupling for an AC derived DC power source.
Never place a Transmitter or Receiver directly into Vero-Board or any similar prototyping board. This will
severely restrict the range. Rather, use small lengths of wire from the prototyping board to the pins of the
Transmitter or Receiver.
A useful antenna, for testing purposes, for both the Transmitter and Receiver on 433MHz is to use a piece of
wire 17.3cm long (23.8cm at 315MHz) soldered directly to the antenna pin.
