The AVR RZUSBSTICK hardware is based a USB microcontroller and a radio
transceiver chip. The AT90USB1287 microcontroller handles the USB interface, the
AT86RF230 radio transceiver and the RF protocol stacks.
For hardware details please refer to Appendix D for the complete AVR RZUSBSTICK
schematics.
4.1 AVR Microcontroller
The 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.
4.2 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.
4.3 Antenna description
The antenna on the RZUSBSTICK is a folded dipole antenna with a net peak gain of
0dB
