Software available

All the software running on Acqua A5 is freely downloadable from the Acme Systems or Atmel web site and is fully Open Source.

The board is fully compatible with the Atmel Atmel SAMA5D3 Xplained board so from the Atmel site it is possible to download and use also Yocto and BuildRoot.

On this site we'll explain how to compile from sources or how to create a bootable microSD using the ready-to-run binary images of a Debian 7.5 with Linux Kernel 3.10.

Price and availability

Actually the most requested model is the ACQUA_256E_N256 so it is almost always available at stock. For the other models may have to wait some time after the order (max 4 weeks).

MicroSD hinge type holder

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

Metallic shield for harsh environment

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

This shield is composed by two parts:

Evaluation boards

To getting started with Acqua A5 we made some cheap boards
called BERTA A5 which have a placement for the Acqua module and some peripherls already mounted.

SAMA5D3 ARM Cortex-A5 Microprocessors

"Based on the ARM® Cortex™-A5 processor, the Atmel® SAMA5D3 series of microprocessor units (MPUs) operates at up to 536MHz (850DMIPS) at under 150mW, delivering a high-performance, low-power platform for cost-sensitive industrial and consumer applications"
