The STEVAL-IPE015V1 demonstration board is a 
class 0.5, single-phase microprocessor-based 
meter with tamper detection for power line

A stepper motor display shows the values of the 
energy measured by the standalone meter.

The tamper detection feature implements two 
current transformers which monitor the live and 
neutral wire currents. 

The STEVAL-IPE015V1 demonstration has a 
10-pin connector to be interfaced to a 
microcontroller or to a PC through a parallel or 
serial programmer for reading data.
