Product description: 4-channel current, voltage and power monitoring HAT for Raspberry Pi - I2C / SMBus - Waveshare 17539
This current, voltage, and power monitoring HAT is designed to simultaneously measure parameters on four independent channels . The module utilizes the INA219 measurement chip, which measures the bus voltage and voltage drop across the shunt resistor, and provides the results for further analysis via the I2C/SMBus interface. The built-in 12-bit ADC and precision 0.1Ω 1% sensing resistors ensure repeatable and stable readings, useful for both prototyping and production applications. Thanks to the standard 40-pin GPIO connector, it is compatible with a wide range of Raspberry Pi boards.
