Description

The STPM33 energy metering evaluation board is

a class 0.2, single-phase meter which includes

tamper monitoring, CT and shunt current sensors

Measured active/reactive power can be output

from two programmable LEDs on the board.

The board can be interfaced with a PC running

evaluation software through an isolated RS232

port, or through the STEVAL-IPE023V1 USB

isolated interface tool for configuration and data

reading.

The board also has SPI/UART pins available to

interface a microcontroller for application

development.
