6NoMi: The Age of Refinement
The 6NoMi RF project, designed for use with Arduino or standalone, is now sporting a major upgrade with a four layer PCB. While removing the castellations of the earlier version and maintaining it’s Arduino compatible pin out, the new four layer design also features a reduction in size at 23 x 30mm.
The 6NoMi is based on the STM32W108 which combines a low power ARM Cortex M3 and an 109dB 802.15.4 radio. IEEE 802.15.4 specifies the physical layer and media access control for low power personal area networks forming the basis of 6LoWPAN, ZigBee, MiWi and many other protocols. The 6NoMi will exploit the multi-threaded Contiki RTOS to build a platform that allows the 6NoMi to play nice with the Arduino development environment through a simple but powerful Arduino library. The 6NoMi will allow Arduino users to create a seamless, end to end, low power network extending from internet to appliance.
