-Apart from the rain gauge and anemometer, the PCB provides inputs for two analogue sensors (nominally solar radiation & UV), and three digital inputs (two I2C). It also has a 9 volt output which may be turned on and off by the WeatherDuino software. A typical use for this would be to control the fan in an aspirated radiation shield. The PCB has a space for a line driver IC which may be needed if the I2C sensors are not mounted close to the transmitter. It's a good idea to fit a DIL socket in this position so that the IC can be easily fitted later if needed.+Apart from the rain gauge and anemometer, the PCB provides inputs for two analogue sensors (nominally solar radiation & UV), and three digital inputs (two I<​sup>​2</​sup>​C).

 RF communication is provided by a small daughter board located near the SMA aerial socket. Other major components on the PCB are a voltage regulator and a MosFET transistor which controls the external power feed. One very useful feature of the transmitter board is a temperature sensor. Although this is not as accurate as the off-board temperature sensor(s) it does provide an indication of conditions in the transmitter box. RF communication is provided by a small daughter board located near the SMA aerial socket.
