The ATSAM4CMS32-DB demonstration board uses Atmel ATSAM4CMS32 to demonstrate the high accuracy single-phase energy metering functions. The ATSAM4CMS32 is an integrated single-phase Energy Metering SoC with 100MHz, dual-core Cortex-M4 ARM processor cores. The board is ETSI format compliant and is designed to interface with CT, Rogowski and Shunt current sensors. The board can interface with ZigBee and PLC communication modules from Atmel.

The demonstration kit includes a metering demo application and Atmel Metrology library for quick out of box evaluation. The users are required to connect their own current sensors to complete the metering demo setup.
