Miniaturized Arm Based Arduinos

For electronics projects where space and size really matters, a miniaturized arm based arduinos can be an excellent solution as it will definitely speed up development efforts especially during prototyping stage. My previous post which was about miniaturized arduinos does not offer much because those were just small arduino uno. What most hobbyist want and I would say an ideal tiny development board should at least be 40Mhz with huge rams and eeproms.

So I tried to search the web again to find arduinos having the above mentioned specs and to my surprise, I only found 1 and another tiny board almost qualified but then it is worth mentioning because of it unique features and it's a little bit more powerful than an ordinary arduino.

Teensy 3.1 is a small and is definitely a miniaturized arm based arduino. It uses the powerful MK20DX256 32 bit ARM Cortex-M4 72 MHz microcontroller and can be program in the arduino ide. The only feature that did not met my requirement is the small eeprom which is the standard 2kb, the manufacturer should have at least inluded an external eeprom ic to compensate for this lackness but overall, the teensy 3.1 will enable hobbyists develop a wide range of small but very powerful devices.
The other arm based arduino is small but is only 16Mhz (that's why it did not qualified) is the rfduino. What is nice about this tiny arduino module is having a bluetooth low energy module on board, this can also be used as an alternative ibeacon device or can be programmed to recieve ibeacon data. enablng other non-ble equipped devices to have the latest hardware in the market.
