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. Small capacitors of 10-100nF can also be used across the power supply to filter high frequency noise. 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. Data should be encoded before it is transmitted over a wireless link to ensure reliability and reduce the effect of interference and cross talk. A range of encoders IC’s are available from RF Solutions, please refer to the RF Solutions website for further information. |
