1 Reference Design Hardware

The schematic and layout are shown in Figure 1 and Figure 2. The design keeps a low component count by using integrated features of the RF430FRL152H such as the internal A/D converter and ROM functions for acquiring sensor measurements from a thermistor (RT1). This design also offers the flexibility to include a 1.5 V battery at TP1/TP2 if data logging is required and the RF field will not always be available to provide power. The hatched ground pour is used for improved RF performance.
