Input 3/5v - Ansu - 06-05-2023
Hello
Is it possible to modify board to work with lower digital input voltages 3 or 5v
RE: Input 3/5v - admin - 06-05-2023
digital input you can use 0v or >4v
0V = logical "1"
>4v = logical "0" , so use dc 5v for logical "0" is no problem.
RE: Input 3/5v - Ansu - 06-06-2023
I thought digital input minimum is 8v for 0
Atleast some boards have that information and AliExpress store replied 12v for input
Edit.
I was talking about dry contact inputs, why need to be 2 different digital input types ?
Edit2.
Now I see in picture where is it's for switches only "dry contact". So it works in low side ?

usually use dry contact with INPUT port, just SHORT with GND or NOT SHORT with GND.
