Relay Bypass PCB and 18V

First of all I'd like to thank PedalPCB for putting out such high-quality stuff in a uniform format. I couldn't be happier with the selection.

Before purchasing, I just want to double-check that there will be no issues with feeding the relay bypass an 18V supply (assume that all of the capacitors I source have a 35V or greater threshold). I looked up the voltage regulator and it can tolerate up to 30V Input voltage. I also have to assume the Microcontroller is putting out exactly 5VDC to flip the state of the relay, but can't be sure without the schematic.

Thanks,

Daeg
 
Yep, you should have no problems running on 18V. The L78L05 has an absolute maximum of 30V In, so the only other concern is the voltage rating of C1. (100nF on the lefthand side of the board)
