I present to you a circuit which is a little outdated, but quite pleasant for some, I saw that this LM3909 is still found and I said to draw a pcb. I added a multi-channel switch, dip switch, which allows us to choose which number we want to display. Maybe you want to dial the number 6 to celebrate with PCBWay.


Notes: pay attention to the display model.

I hope you like this board, if so, maybe you can help me with a LM3909 IC :).
