I’m exploring including the 2 knob job circuit in a pedal’s circuit and I’m wondering if it has a ground layer? It seems there is to connect SW1A with G but if I don’t need the second ground pad, could I just connect SW1A with the ground pad at the top left and not need a ground layer? Thanks for your help!!
All board grounds are connected to each other that particular ground is if you’re using it for a volume knob see the build doc wiring for a volume knob (voltage divider) where you would need to ground lug 1 via a small jumper making it more convenient allowing you to leave a longer wire out
SW1A is the common anode bi colour LED ground connections, you don’t need to separately ground that
Thanks for your help! It doesn’t look like the top left 2 grounds are connected to anything, does this mean they’re connect via a ground layer inside the pcb? (Sorry if this is obvious, I’m new to pcb design). Thanks so much!
Yes they’ll be connected in one of the layers
You can continuity check all ground pads are connected with your meters continuity test function
I don’t know your experience but here’s a PDF just in case you’re not familiar with continuity testing
