No because it's a direct contact driver, with the spring. There's stress on the PCB because of the battery/spring so the thinner one might not be as strong, plus if you had to make up for a gap between the driver and contact to the tube, it's extra unnecessary work.

Are you using mostly 0805 parts? I’m trying to create a BOM on digikey or mouser using: :nerd_face: https://oshpark.com/shared_projects/F80rN1sk

Yes - that's a pretty good list, but yes - I use 0805's. Best to reference DEL's thread: https://budgetlightforum.com/t/-/44006

I fixed your link - BLF likes to append the /quote onto links...

Some important notes:

• we got better FET;s now
• 7135 must be the raptor claw version
• R1 and R2 are not needed for NarsilM or Anduril with a 3.7V battery source (not 2 or more in series) - R1/R2 are a voltage divider used to read voltage externally. As long as you are using 3.6V battery setup, Anduril defaults to internal voltage reading. You can leave R1 and R2 pads empty.
• MCU must be a ATTiny85 for NarsilM or Anduril
