Serial.println not working on Electron

I'd add some filtering to the supply.
Especially during/after cranking you might get harmful spikes that exceed the 14V by far.
This link talks about cars but in priciple this goes for motor bikes too.

The regulator design is from the open-source OpenXC project by Ford research. I used that for the 1st version since it’s an automotive-grade design. The big cap is to survive low voltages during cranking. The power supply is one area I’m changing in successive PCB revisions. I’m looking for a good balance between component size, cost and ability to survive automotive transients like these: [image]
