Introduction
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 Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards
4-ch monitoring, via I2C/SMBus interface
Onboard 0.1O 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)
Specifications
Operating voltage: 3.3V/5V
Control interface: I2C/SMBus
