    This board not really works with 5V, because the Voltage regulator not LDO, it needs at least 7V for a stable 5V output. I used an USB charger as a supply, and the result was very uncertain (the otput was only 3.8V and the IC didn’t tolarate it). After I shorted the regulator’s input and output it worked fine. The current transformer’s burden resistor is a 100 mOhm resistor and according to it’s datasheet it requires 50 Ohm for proper working (this will cause much bigger voltage, but you can use a voltage devider).

    By the way, the product works with Arduino and MCU.
