NU-FitHole hole size helper

As mentioned in an earlier post I’ll try to do one small PCB project every week and then send for PCB’s of it every Monday.


This weeks PAW will be extremely simple – it’s not even a breakout board, but it might still come in handy for people making PCBs. The FitHole is a tool for testing what drill size that best fits a part that you’re making a library footprint for.

It have holes in sizes from 0.4 mm to 2.3 mm in increments of 0.1 mm, plus a hole that is 3.0 mm as well as a 6.35mm that is Seeedstudios largest standard drill size.

The 6.35-hole might also be used to put the tester on your keychain so you don’t lose it. 🙂
