This is the signal monitoring board as seen on YouTube in my generator monitoring video. My records show these files as a revised version after the video was made, but I don't see anything having changed. It looks like it still has the errors that will require you to place R7 awkwardly to get it to the display connector and to run the analog reference from J11 to the ground for the Vsens signal (bypassing where it goes to microcontroller ground). This is very much not a commercial product and is provided for low-energy, low-voltage, hobby/educational use only. Do not try to use this with a generator or any mains voltage application without consulting a qualified individual. These files are provided so you can have a small number of these PCBs printed for your personal, noncommercial use only.
