The DSYS25 platform is a 25mm x 25mm module comprised of an Atmel AVR ATMEGA 128 microcontroller and a Nordic nRF2401 Transceiver. Additional functionality, such as sensing, is added by stacking layers on the basic unit. A summary of the basic unit characteristics is highlighted next:

• Processor
• ATMEGA 128 4MHz
• 2 serial ports
• Radio
• Nordic nRF2401
• GFSK Transceiver
• Frequency 2400-2524MHz
• Data rates from 0 to 1Mbps
• Address and CRC computation
• ShockBurstTM for ultra-low power and relaxed MCU performance
