Day 19: Edge Board 5up Digital Input Board
09/27/2023 at 22:05 • 0 commentsAn edge board containing five opto isolated inputs. All inputs are active HIGH. Each input comes with an input pin, a 5v and a gnd connection.
If I were to do this again, I would probably make a jumper that can switch between the 5v and whatever the bus voltage was.
