BTnode is an autonomous wireless communication and computing platform based on a Bluetooth radio and a microcontroller. It serves as a demonstration platform for research in mobile and ad-hoc connected networks (MANETs) and distributed sensor networks. The BTnode has been jointly developed at ETH Zurich by the Computer Engineering and Networks Laboratory (TIK) and the Research Group for Distributed Systems. Currently, the BTnode is primarily used in two major research projects: NCCR MICS and Smart-Its.
The low-power radio is the same as used on the Berkeley Mica2 Motes, making the BTnode rev3 a twin of both the Mote and the old BTnode. Both radios can be operated simultaneously or be independently powered off completely when not in use, considerably reducing the idle power consumption of the device.
The BTnode rev3
* Microcontroller: Atmel ATmega 128L (8 MHz @ 8 MIPS)
* Memories: 64+180 Kbyte RAM, 128 Kbyte FLASH ROM, 4 Kbyte EEPROM
* Bluetooth subsystem: Zeevo ZV4002, supporting AFH/SFH
* Scatternets with max. 4 Piconets/7 Slaves, BT v1.2 compatible
* Low-power radio: Chipcon CC1000 operating in ISM band 433-915 MHz
* External Interfaces: ISP, UART, SPI, I2C, GPIO, ADC, Timer, 4 LEDs
* Standard C Programming, TinyOS compatible
