Does the item on https://www.amazon.com/DROK-Multimeter-Charge-Discharge-Electricity-Overvoltage/dp/B01M5CWR2P/ref=pd_ybh_a_1?_encoding=UTF8&psc=1&refRID=YSGR7ETP74D9XT7NYAJQ actually come with the measurement board? The 30A model states that it does, but does the 100A model come with the PCB that holds the shunt? Also, does this connect wireless via direct connect to the measurement board, or will it be over another protocol such as WiFi?

Thank you
