A 4-channel power parameter monitoring module dedicated to Raspberry Pi minicomputers. It has a standard 40-pin GPIO expansion connector and has 4 measurement channels and a built-in 0.1Ω sampling resistor with 1% accuracy, which allows current measurement up to 3.2A. The module uses a 12-bit analog-to-digital converter (ADC), which enables accurate voltage and current measurements.

In addition, the module allows direct calculation and output of the measured power value through an additional multiplier register. It uses an I2C/SMBus communication interface and has derived I2C pins for connection to other development boards. The voltage measurement range is 0 to 26 V, and the current measurement range is ±3.2A. The module requires a 3.3V or 5V power supply.

The measurement module is ideal for use in projects that require voltage and current measurement, such as power applications, robotics, control systems and other Internet of Things (IoT) applications. It is easy to use and can be easily integrated into Raspberry Pi and other devices that use the I2C/SMBus interface. Full documentation and usage examples are available on the product page.
