README
hardware/README.mdscuznet hardware
Provided here solely for informational purposes is a prototype hardware design that was built for testing the scuznet firmware. This is the second revision of the hardware, which has the following known issues.
- A USB connection is provided but there is (as yet) no hardware support for it. I must have lost my mind when selecting this part, it is a PITA to solder. Version 2.1 of the board should replace this with something easier to work with.
- The power connector footprint is still too big and wiggles around while soldering.
This version has not received significant testing yet.

Questions
How big is the Scuznet PCB?
It measures 100 × 80 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Scuznet use?
103 parts, built around the ATXMEGA64A3U-AU, 74LVTH245SJ, ENC28J60-I/SP and 74LVC14AD. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Scuznet KiCad files?
From the saybur/scuznet repository on GitHub, at the commit this page was made from: the board is hardware/scuznet.kicad_pcb and its schematic hardware/panels/back/scuznet_back.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Scuznet design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
