ARM is quite famous architecture, it almost consume entire smart phone market. Most of the smart phone you have is ARM based. And now, ARM has also invade the microcontroller sector. With the 32-bit ARM processor and high processor speed, not to forget the rich peripherals, this ARM Cortex-M0 microcontroller offer 6X the power of 8-bit microcontroller.

This is CT-ARM, an Arduino UNO R3 compatible 32-bit ARM Cortex-M0 microcontroller board. It is compatible with Genunio UNO R3.
