4 Channel Current/Voltage/Power Monitor Raspberry Pi HAT
4 Channel Current/Voltage/Power Monitor Raspberry Pi HAT is a 4 channel current and power monitoring HAT designed for Raspberry Pi. Via I2C or SMBus interface, it is easy to monitor the current, voltage and power consumption of each channel, as well as the voltage between both sides of the sampling resistor.
