I’m designing a pcb to use my electron in a vehicle. I have everything pretty much sorted out, except the power supply.
It’s a 12v system with a secondary battery isolated to run accessories, and I’m using a RECOM DC DC converter that outputs 5v at 2 amps. The power is fed to VIN on the Electron. digikey link
It gets too cold to use a lipo here. If I can supply 5v/2A is it neccessary to use a capacitor on vin? I don’t seem to have any trouble testing without it, but I’m not sure if a small one would be advisable.
