The AVR RZUSBSTICK hardware is based a USB microcontroller and a radio transceiver chip. The Atmel
AT90USB1287 microcontroller handles the USB interface, the Atmel AT86RF230 radio transceiver and the RF protocol
stacks.
For hardware details please refer to Appendix D for the complete AVR RZUSBSTICK schematics.
3.1 AVR Microcontroller
The Atmel AT90USB1287 is a device in the family of AVRs with a low and full speed USB macro with device, host and
On-the-go (OTG) capabilities.
3.2 Atmel Radio Transceiver
The AT86RF230 is a 2.4GHz radio transceiver that is tailored for a wide range of wireless applications. Low power
consumption and market leading RF performance makes it an excellent choice for virtually any type of networking
device. Support for IEEE 802.15.4 (Automatic acknowledge of packets, address filtering and automatic channel access)
type of applications is available through an enhanced layer of functionality on top of the basic radio transceiver.
3.3 Antenna description
The antenna on the RZUSBSTICK is a folded dipole antenna with a net peak gain of 0dB.
