The Atmel AT86RF233 is a feature rich, extremely low-power 2.4GHz radio transceiver designed for industrial and consumer ZigBee/IEEE 802.15.4, RF4CE, 6LoWPAN, and high data rate 2.4GHz ISM band applications.
The AT86RF233 is a true SPI-to-antenna solution. All RF-critical components except the antenna, crystal, and de-coupling capacitors are integrated on-chip. MAC and AES hardware accelerators improve overall system power efficiency and timing. Therefore, the AT86RF233 is particularly suitable for applications like:
• 2.4GHz IEEE 802.15.4 and ZigBee systems
• RF4CE systems
• Energy Harvesting systems
• 6LoWPAN systems
• Wireless sensor networks
• Industrial Control
• Residential and commercial automation
• Health care
• Consumer electronics
• PC peripherals
AT86RF233主要特性:
• High Performance RF-CMOS 2.4GHz radio transceiver targeted for IEEE® 802.15.4, ZigBee®, RF4CE, 6LoWPAN, and ISM applications

REB233-XPRO擴(kuò)展板
This user guide describes how to get started with the Atmel® REB233-XPRO extension board.
The extension boards is targeted for evaluating the features of the Atmel AT86RF233 radio transceiver.
Xplained Pro is an evaluation platform that provides the full Atmel microcontroller experience. The platform consists of a series of Microcontroller (MCU) boards and extension boards that are integrated with Atmel Studio, have Atmel Software Framework (ASF) drivers and demo code, support data streaming and more.
Xplained Pro MCU boards support a wide range of Xplained Pro extension boards that are connected through a set of standardized headers and connectors. Each extension board has an identification (ID) chip to uniquely identify which boards are mounted on a Xplained Pro MCU board.
