The G25 Arietta, a promising newcomer

Cheap, an ARM SoC, an optimized Linux distribution, the GPIO, the I2C support, PWM. You might think that I am talking about a Raspberry Pi and yet not ! It's a new comer : the Arietta G25 from ACME System.

Raspberry Pi Home Server - Arietta G25

By reading the forum francophone from the association for the promotion of Raspberry Pi, I read a topic on the Ariette G25. Uggy speaks of this small map and its capabilities.

The objective is a size reduced for the Maker and other DIY card, with of course, extended capabilities :

  • A CPU Atmel AT91SAM9G25 SoC (ARM9 @ 400 Mhz)
  • DDR2 memory with 128 or 256 MByte
  • Supply 5V via the microUSB port or 3.3Vdc via a connector
  • A small size of 53x25mm
  • Consumption of 59mA to 85mA depending on the phases and the model. Consumption increases if you use the wifi module

The ACME company (Yes Yes as in the Warner cartoons !) provides availability for the 5 next years !

At the level of the connectors is the fiesta ! No less than 40 PIN that you can use to :

  • 2 bus I2C
  • 3 serial UART ports
  • 3 USB ports which 1 who has dedicated connectors
  • 4 lines PWM
  • 1 SPI bus
  • 1 port I2S
  • 4 analog to digital converters
  • 1 debug DPI interface
  • 1 micro USB connector to connect the card to your computer
  • 1 Configurable LED
  • 1 configurable push button
  • 1 Connector
  • 1 support micro SD
  • 1 support for a Wifi b module, g and n
  • Up to 29 GPIO supporting 3.3V

Nothing that much !

Here is a small diagram containing all the information

About the operating system, on the micro SD card you can install a Debian specially optimized for the CPU of the Arietta G25 !

ACME offers or download an image for your card (with a kernel 3.16.1), either build yourself an image with packages that you are interested in.

Once the OS is installed, you then have access to all packages (compiled for arml) classics. To you, the enjoy of C programming, Python, PHP or Node JS ! For Internet access, It must pass either by wifi USB port connected to your computer via adapter (sadly no LAN port …)

Finally to help you to master the various connectors, ACME offers a dedicated page allowing you to understand the usefulness and the configuration of each pin.

The comparison with the Raspberry Pi, even if it is tempting, does not really make sense. Because the differences are too numerous ! CPU, GPU, HDMI output, audio output, size, consumption, etc. It is not really the same thing.

The recent arrival of the Arietta G25 has a reduced community and if you're not with a confirmed technical level you may quickly find yourself blocked. Hopefully, ACME was able to partially anticipate the problem (Unlike the Banana Pi for my opinion) by offering several tutorials (but basics ones) and documentation.

In the end, I find this card promising for connected objects (Internet Of Things ? :-) ) for which it seems to suit very well especially with its consumption and reduced and its many output pins.

Feel free to share your feelings about this card in the comments or even better your experience if you are a happy (or not) owner of the Arietta G25.

    very nice product , some difficulties to run the wifi on my box ( software configuration )

    and I find it a great lack of support, I've always failed to properly install lirc ( )

    I guess being stuck by the gpio poorly defined in my configuration , suddenly I think go on other projects …

    Thanks again to chris for his contest which made me discover the arietta !

  • Hello, recently it is used with buddies to develop embedded sensors hives (openbeelab). It is not always easy at first (including wifi, the tutorial is good but a little light), but not be discouraged, I'm really not an arrow, but with their tutorials I managed to compile kernels dedicated linux, debian rootfs adhoc and even bootstrap changed while I did not even know what it was… What's great is that it consumes little enough to make boarded small solar panneaus (80My), and it can be shut down and turn back alone with the RTCwakeup. I strongly advise to control the DPI (débuggeur) avec la carte sinon pas possible de démarrer un nouveau kernel (faut faire un depmod -a pour pouvoir s’y connecter avec l’usb) pour par exemple activer les adc.
