Cool. Yeah, you are clearly in it for the pain. With your simple changes I’m sure someone here would be willing to generate a PCB if you had a change of heart.
- You need to keep D1 because LD2981 does not have reverse polarity protection, right?
- I think you’ll need a second fly wire to get from the protected side of the diode (towards the outside of the PCB) back to Vin on the LD2981.
- You’ll need the support caps for LD2981 I suppose, so you’ll either need to keep C1 in place and add an input cap for the LD2981 somewhere or you’ll need to strip C1 and place both input and output caps somewhere for the LD2981.
- In order to use C1 you’ll need to cut both of the other traces leading away from the via - the one that goes to D1 and the on that goes to R1.
- Once you consider your cap needs it seems easiest to me to cut the trace that feeds the divider and use a fly wire to attach the divider to BAT+.
So that looks like 3 fly wires to me, several cut traces, and stacking 1 cap (the input cap) on top of the pins for the LD2981.
