STMicroelectronics X-NUCLEO-PM33A1 Expansion Board Based on STPM33
STMicroelectronics X-NUCLEO-PM33A1 Expansion Board is based on the STPM33 electricity metering IC, which can measure AC and DC sources with an accuracy of 0.1%. It can be powered through the STM32 Nucleo development board or an external power supply (3.3V). The current measurement is done using the shunt mounted on the board. The connector is available to measure the current using CT.
The STMicroelectronics X-NUCLEO-PM33A1 expansion board can easily be plugged into any STM32 Nucleo development board and is compatible with the Arduino® UNO R3 connector pin assignment. The user can stack other expansion boards to evaluate different devices that work with electricity metering.
