The Silicon Laboratories 2.4 GHz 802.15.4 Development Board provides a hardware platform for the development of 802.15.4 and ZigBee Wireless Personal Area Networks. The Development Board features the following key components: the Silicon Laboratories C8051F121 microcontroller; the Chipcon CC2420 RF Transceiver; and the Silicon Laboratories CP2101 Universal Serial Bus (USB)-to-Universal Asynchronous Receiver/Transmitter (UART) bridge.

This development platform can be used with an 802.15.4 Media Access Controller (MAC), with a complete ZigBee stack, or to develop application-specific firmware. This application note describes the hardware features and details of operation.
