We do have a winner. C2 is a dead short.
The datasheet calls for 22µF input capacitor. The board has three input capacitors..?
Thoughts on where to go from here? I don't really have many parts lying around. Just some THT electrolytic caps.

Should I take off C3 and maybe C1 to check what they are (and turn a tarduino into a capacity meter to do so)?
