Description

Note: Without bottom board

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 Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards

4-ch monitoring, via I2C/SMBus interface

Onboard 0.1Ω 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/for Arduino/STM32)
