Q & A
《Q108》 For the BSI-3.3S12R0F, is the S-GND (pin #2) on the GND side of the remote ON/OFF connected to the -Vin (pin #4) connected internally? Can it be connected to -Vin?
The S-GND and -Vin are connected internally. Therefore connecting to the -Vin pin is possible however since large currents flow through -Vin, a voltage difference between GND may occur. Therefore using the S-GND pin is recommended
