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

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"
