MC2 Post 1712 The Next Strange Thing in computing is White Space

Ofcom, Google, Microsoft, others launch visionary “white space” exploration


Ofcom, the U.K. counterpart to the U.S.’s FCC, has commenced the largest exploration of “white space” frequencies the world 
has ever seen.


Linux-capable Arduino TRE debuts at Maker Faire Rome

The Arduino project announced a third-generation Arduino single board computer featuring a dual-processor architecture, and able to run a “full Linux” OS. The Arduino TRE features both a 1GHz 32-bit TI Sitara AM335x 32-bit ARM Cortex-A8 processor, for running Linux, and an 8-bit Atmel ATmega microcontroller, for AVR-compatible 
control of “shield” expansion modules.

Preliminary specifications

The Arduino website lists these preliminary specifications for the Arduino TRE SBC:

    Atmel ATmega microcontroller subsystem:
        Atmel ATmega32u4 @ 16MHz
