17 / 28 page ![]() EVBUM2775/D www.onsemi.com 17 Control Board Headers Schematic of control board headers can be seen in the Figure 20. The headers have Arduino Due footprint. The applied control board has to contain 3V3 power supply as it is also used for supplying current measurement op amps and comparator for over−current protection. Low pass filters for current and voltage measurement signals are placed closed to the headers (see CON4). When connecting the control board to the PC, do not forget to use isolator. Figure 20.
