The STMicroelectronics Electricity Metering IC Expansion Board is based on the STPM33 metering IC, capable of measuring both AC and DC power sources with 0.1% accuracy. It can be powered via an STM32 Nucleo development board or an external 3.3 V supply. Current measurement is performed using an onboard shunt, with an additional connector available for CT-based current sensing. The expansion board is compatible with the Arduino UNO R3 connector pin assignment.
RoHS compliant
Onboard EEPROM for saving the metering data
On-board digital isolators on UART and SPI connections to enable users to evaluate STPM33 device by isolating from MCU
LEDs connected to STPM33 for checking pulses directly from the device
Connectors for external CT connections
Capable of measuring both AC and DC sources
Compatible with STM32 Nucleo boards
