Arietta G25 is a tiny system-on-module (SoM) powered by Atmel SAM9G25 ARM9 processor and running Linux that sold for a discount earlier this year (9.9 Euros) for early backers, and is now available for 20 Euros, and support an optional Wi-Fi module for as low as 7 Euros extra. Acme Systems, the company who made the board, is now considering designing and manufacturing an open source hardware baseboard for the module, and is asking for feedback from the community before going ahead.
Currently the idea is to have a baseboard with the following:
- Arietta G25 SoM connector (Vertical mount)
- 1x USB Host port
- I2C Sensors – Temperature and Humidity sensor, Light sensor
- Mosfet output for RGB led strip
- 2x relay output
- 1x filtered dry input
- 2x servo RC motors output
- Audio interface with embedded microphone and jack for PC speakers using Wolfson WM8731 codec
- Expansion headers for external modules already available and made by the company:
- SPI bus for stepper motor interface or oLed 1.5 inch 128×128 pixel
- I2C & serial buses for RS232 interface, RS485 interface, XBee adapter, MBUS Adapter, MEMS module, LCD 16×2 display, 4D systems adapter, Daisy proto board
The initial schematic (PDF) is already available, and if you have an Arietta G25 SoM, or plan to, and are interesting in the EDU baseboard, you can leave your feedback on the company forums, or contact them by email or twitter.
