| - | Each WeatherDuino transmitter comprises a single printed circuit board (PCB) approximately 100mm x 60mm. The PCB has two main functions. First, it provides an interface to a number of sensors via connectors mounted around two sides of the board. Second, it provides a radio frequency (RF) link between an Arduino Nano microcontroller and a remote WeatherDuino receiver. Two RJ45 Ethernet-style sockets provide connections to a rain sensor and an anemometer. Many low-cost wind/rain sensors use these connectors | + | Each WeatherDuino transmitter comprises a single printed circuit board (PCB) approximately 100mm x 60mm. The PCB has two main functions.

| 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.
