MicroSD hinge type holder

To open the Acqua microSD holder apply a gentle pression to the metallic shield then shift it ahead.

Metallic shield for harsh environment

If you plan to use Acqua A5 in an electromagnetic noisy environment (for example near DC motors) it is possible to place a metallic shield made by Wurth Elektronik to better protect the board from external EMI.

This shield is composed by two parts:

  • a metallic open frame to be welded to the board
  • a removable metallic cover

Software features

  • This board is fully supported inside the Linux Kernel main stream http://www.kernel.org. Thanks to this fact it is possible to try also the very latest Kernel releases. On this site we'll release up to the latest longterm versions.
  • All the kernel drivers are fully open source and available directly on the official Linux repository.
  • On the main index is available the step-by-step documentation to install Linux from scratch.
  • Ready-to-use binary images are available on the download page
  • Ready-to-buy-and-use microSDs are also available on our Acme Systems eShop
  • Thousands of open source applications are available from the Debian and Buildroot repositories.
  • ARMHF is the architecture to select for RoadRunner and Acqua boards. ARMEL is the architecture to select for Aria and Arietta boards.
