Hello, perhaps someone has asked this question before but i'm certain many or some of you have used this device before.
On the board there is a ground(GND) pin, where does this ground pin connects to on the mosfet ?? drain ?? I'm assuming ?? or are both HV(gnd) and LV(gnd) connected together ?? as in jumper wire from gnd of 5V device directly to the gnd of the 3.3V device ??
I understand that 5V goes to HV which is connected to drain of the BSS138 and 3.3V goes to LV and which is tide both source and gate
but no where do they show ground wire connected to anywhere.
I would like to know which port on the BSS138 is the ground pin connected to.
