Waveshare 4-ch Current/Voltage/Power Monitor HAT for Raspberry Pi, I2C/SMBus Interface, Easy to Monitor Each Channel's Current, Voltage, and Power Consumption

Overview This is a 4-ch current and power monitor HAT designed for Raspberry Pi. Via the I2C or SMBus interface, it is easy to monitor each channel's current, voltage, and power consumption, as well as the voltage between both sides of the sampling resistor. Features Standard Pi 40PIN GPIO extension header, fits Raspberry Pi series boards 4-ch monitoring, via I2C/SMBus interface Onboard 0.1 1 sampling resistor, allows measuring bi-directional current up to 3.2A Embedded 12-bit ADC, supports multiple successive converting, 0~26V voltage measuring range Directly calculate and output measured power value through additional multiply register I2C control pins for connecting with other host boards Comes with development resources and manual (examples for Raspberry Pi/Arduino/STM32)
