Compare to original IBM PC

The original IBM PC had similar memory size (if you count Floppies as Flash!), much slower clock was much larger and cost thousands of dollars...

@TonyTib: There's a lot of incredible values out there.

What woudl be reall yinteresting would be to come up with some way to compare the computational capability of say a Raspberry Pi with some old computers like the Mark 1 and ENIAC and so forth -- and also compare the costs of purchasing one...

@TonyTib: There's a lot of incredible values out there.

It really is mind-blowing -- the sort of computational power we're talking about for a few dollars would have cost an unimaginable amount in the not-so-distant past.

There's a lot of incredible values out there.  For performance per dollar, here are some more:

1. ST F401 Nucleo (mbed programming, Arduino + Morpho headers).  $10 for Cortex-M4, 84 MHz, 512K flash, 96K SRAM

2. TI Tiva TM4C1294C Connected LaunchPad (Energia or CCS IDE, 2 BoosterPack Headers).  $20 for Cortex M4 at 120MHz, 1024Kflash, 256K SRAM, Ethernet

3. Raspberry Pi.  Definitely the MIPS/$ winner with 700MHz of ARM goodness for $25.

4. BeagleBone Black.  A bit pricey at $55 for Rev C, but has by far the coolest peripherals (PRU, QEP, PWM, etc) and highest speed (1GHz, 4G eMMC, etc).

All of these are fully assembled, have decent communities (although not Arduino sized), and fairly easy development.

@thiago lima: I want to buy one soon!!! :) My first cortex m0+ arduino.

Isn't it amazing how powerful these things are becoming? Did you see my recent blog about the Teensy 3.1? This is an Arduino-compatible development board boasting a 32-bit ARM Cortex-M4 processor core running at 72 MHz with 256KB Flash and 64KB SRAM -- only $19.80 fully assembled!!!

Hello Max.

Excellent article!

The microcontroller of this Arduino is the Atmel ATSAMD21G18A-AUT (http://arduino.cc/en/uploads/Main/Arduino_Zero_front.png) , 256 Kbytes of Flash.

I want to buy one soon!!! :) My first cortex m0+ arduino.

@Anand: I think Arduino has a very good future in IOT development...

I think you might be right -- I think one part of the IoT in the future will be that non-professionals will want to create their own devices, and the Arduino will facilitate this. Even for professionals, they may want to focus on their "secret sauce" and leverage the proven low-risk Arduino platform as a base.

Arduino integration is a very economical and modulated way towards an independent project developmental approach. Using Arduino boards not only creates ease of use but also, the IDE of Arduino is very understandable. I think Arduino has a very good future in IOT development, because major IOT kits would benefit amazingly from the modulated approach of the embedded systems of the Arduino.

@halherta: I'm currently an educator myself and I use the AVR microcontroller in my Embedded Systems courses.

I've never been a formal educator, but I have given training classes and I've really enjoyed doing so. I think thinks like the Arduino are FANTASTIC for getting non-technical folks started with microcontrollers. Thanks so much for sharing youe experiances with the rest of us.
