I got my sticky hands on some very nice vintage LED-displays, and some days ago i got a pack of nice prototype-PCB’s from eBay, so of course i had to make two small test-boards for these displays 😀
This one is for 4 pcs. of TIL311, intelligent Hexadecimal display (shows 0-9, A-F)
The next board is for a DL1416 display. It can display all numbers and some Alphanumeric digits. It has a 7-bit Data-bus.
The plans for them? Well i have enough of both types to warrant the time needed to layout a design for a very limited-edition wristwatch
