Farhan,
The unit I received at FDIM works fine with Vcc from the barrel jack, but not from the battery pack.? ?
Peeking at the PCB, the power circuit has changed from the schematic you posted on Dec 27th:? there are polarity protection diodes for each input now.? But it looks like batt(-) erroneously goes to the barrel jack instead of ground.? Would you mind checking it?? ?Should I cut this trace and add a wire to ground?? Or is there a better method?

Farhan,
I heard your lecture at FDIM and purchased one of the units but need instruction in how to use it.? Github only has the upgraded code files.? Please advise.
