Acme_Acqua_A5 Back For environments with lots of electromagnetic noise (e.g. DC motors), a metallic shield made by Wurth Elektronik is available as an option. They currently have a very basic baseboard called Berta A5 basic (9 Euros) with the three connectors for the SoM board, and breadboard area (2.54 pitch) for easier access to various signals. Another base board with relevant connectors (USB, LCD, Ethernet…) is also in the work.

The company also provides software documentation showing how to build Linux 3.10, generate an Embedded Debian Grip 7.3 root file system, as well as various tutorials. The board is software compatible with Atmel SAMA5D3 Xplained board, so the instructions to use the Yocto Project or Debian 7.4 should also work.

Acqua A5 SoM is available now for 49 to 69 Euros in single quantity depending on options, and as low as 37.24 Euros in 5K+ quantities. Various accessories (Micro SD cards preloaded with OS, connectors, power adapter…) are also available, You can find more information on Acme Systems Acqua A5 product page. The company is also working on an open source home automation project based on the SoM called OPEN yooquik, but this will probably be the subject of another post once it becomes available.
