If you think that the Raspberry Pi is big and has a lot of unnecessarily function, try the Arietta G25. Rival of Intel Edison. The dimesion of board is little, but it has a more powerful.
Short comparation of parameters with Intel Edison:
| Intel Edison | Arietta G25 | |
| Type of processor | Intel Atom 500MHz (Silvermont) and 32bit Quark (100 MHz) | Atmel AT91SAM9G25 SoC (ARM9 @ 400Mhz) |
| RAM | 1 GB LPDDR3 | DDR2 128MB or 256MB |
| FLASH | 4GB | a? 64GB |
| Communication | WiFi Broadcom 43340 802.11 a/b/g/n, BlueTooth 4.0 | WiFi 802.11b/g/n |
Next features of Arietta G25 are: 1x full speed USB, 1x host/device USB, 1x host USB (it used for WiFi adapter), 3x UART, 2x I2C bus, 1x SPI with frquency from 5 to 50MHz, 4 channels PWM, 4 channels 10bit ADC, debug interface.
The device supported Linux Kernel version 3.16.1, Debian Wheezy.
The device is open-source from firmware during software to toolchains.
You can program it in C, C++, Python, Java, Perl, PHP, Node JS, Lua, Basic or Shell.
You can use web IDE Codiad for programming.
And price? Version with 128MB DDR2 RAM costs 25 Eur, 256MB DDR2 RAM costs 30 Eur.
