Sweet! I didn’t think DR would be able to handle 100% FET. I might need to build one of these!

Standard - 100% FET

Or

219 - 50% FET

When did you switched to 0402 LEDs?

Do you find them easier to manage?

Do you use Eagle to design the PCBs? If so, is it the Free Version? If not, What software do you use?
