Motorbike battery as a power source for particle electron

[ScruffR]

Automotive voltages are a bit more temperamental than the figures (e.g. 12C DC) give away
Although on a motorcycle you might not see the same extremes as in a car, but have a look at this thread

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]
