Aria G25 - Low cost Linux Embedded SMD module

Aria G25 is a cost-effective System-on-Module (SoM) thought of to drastically reduce the development time needed to design a low-power and low-EMI Linux Embedded device.

The more complex hardware like CPU, RAM, Ethernet, power and EMI components are integrated on a single SMD component in just 40x40 mm (1.57x1.57 inch) using an complex eight layers PCB permitting hardware designers to create their simple and cheap carrier boards.

Main features

  • I2C: up to 2 I2C buses
  • SPI: up to 2 SPI buses
  • GPIO: up to 60 GPIO lines
  • A/D: up to four channel @ 10 bit

  • Power supply: single at 3.3 Volt DC
  • Consumption: see consumption...
  • Line level: TTL 3.3V
  • Temperature range: 0-70 °C and -20 +70 °C (-E version)
  • Size: 40 x 40 mm (1.57x1.57 inch)
  • Weight: 5g
  • Pads pitch: 1.27 mm (50 mill)
  • PCB layers: 8
  • User configurable led on board

Other features

Software environment and development tools

Aria G25 is designed to boot a Linux Embedded distribution compiled for ARM9 architecure from a microSD or a SD card.

We propose, by default, a ready-to-use Linux Debian distribution stored on a microSD card.

Some ready to use bootable microSD cards are available on the microSD on-line catalog but they can be generated by yourself from binaries or from the sources following our tutorials. The basic requirement to do that is to have a Linux Ubuntu PC.

Thanks to Linux on Aria G25 it is possible to use almost any language. In the tutorials page are listed a lot of examples to manage the embedded peripherals in C or Python languages.

The C compiler and the Python interpreter are pre-installed by default on our microSD. A small web server (Lighttpd) and PHP language interpreter are also installed for the web developers.

More languages, tools, web servers, etc are available from the official Linux Debian binary repositories for armel architecture and can be installed in few minutes directly from Internet to your board.
