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
32KB flash, 2.5KB SRAM; 1KB EEPROM
