We go through a lot of prototype PCBs, and end up with lots of extras that we’ll never use. Every Sunday we give away a few PCBs from one of our past or future projects, or a related prototype. Our PCBs are made through Seeed Studio’s Fusion board service.
On this super-late PCB Sunday we’re giving away two boards for the USB Universal LCD backpack. The backpack controls LCDs with up to 16 interface pins at 3.3volts or 5.0volts, including common HD44780 character LCDs and larger graphical LCDs. This project was developed collaboratively in the forum. See it come to life here, and check out the design history and work-product on the wiki.
Get an assembled USB Universal LCD backpack for $15.

Some stuff:
- Yes, we’ll mail it anywhere in the world!

- Limit one PCB per address per month please.
- Like everything else on this site, PCBs are offered without warranty.
