sky: Tmote Sky / TelosB
This platform is Contiki’s historical default platform. It is still in Contiki-NG, mostly for emulation purposes with MSPSim in Cooja.
250kbps 2.4GHz IEEE 802.15.4 Chipcon Wireless Transceiver
8MHz Texas Instruments MSP430 microcontroller (10k RAM, 48k Flash)
Integrated ADC, DAC, Supply Voltage Supervisor, and DMA Controller
Integrated onboard antenna with 50m range indoors / 125m range outdoors
Integrated Humidity, Temperature, and Light sensors
Hardware link-layer encryption and authentication
The platform datasheet is available at: http://www.eecs.harvard.edu/~konrad/projects/shimmer/references/tmote-sky-datasheet.pdf
Due to RAM and ROM limitations, the Sky can only run selected subsets of the stack, e.g. RPL+TSCH does not fit with downward routing, and very few logs can be enabled in general.
