The ADE7953 evaluation kit includes two boards that should be used together to evaluate the silicon. The smaller board, named ADE IO INTERFACE BOARD Z (the interface board), consists of an NXP LPC2368FBD100 microcontroller that handles all communications from the PC to the ADE7953. The larger board, named EVAL-ADE7953EBZ (the evaluation board), includes the ADE7953 energy metering IC, associated filtering, and isolation to allow high voltage inputs to be used. The two boards should be connected together using the 25-pin connector included in the evaluation kit. The connector is labeled P2 on the interface board and P7 on the evaluation board.
