Product overview
概要
The X-NUCLEO-PM33A1 electricity metering IC expansion board is based on the STPM33 electricity metering IC with a capability of measuring both AC and DC sources with accuracy of 0.1%.
It can be powered through the STM32 Nucleo development board or through an external power supply (3.3 V).
The current measurement is done using the shunt mounted on the board.
The connector is available for measuring the current using CT.
The X-NUCLEO-PM33A1 expansion board is compatible with the Arduino® UNO R3 connector pin assignment and can easily be plugged onto any STM32 Nucleo development board.
You can stack other expansion boards to evaluate different devices that work together with the electricity metering.
