It implements four channels with current sensors controlled by two Infineon PSoC 4 (CY8C4245) microcontrollers to measure voltage, current and power.
Channel 1 and 2 are isolated channels implemented with two Melexis integrated magnetic current sensors. Channel 3 is designed for current measurement via USB.
Channel 4 can measure up to 300mA / 5V via USB using the same PSoC-B microcontroller as channel 3.
