README
readme.mdr68 std
This a 68% board, like a tada or sabre.
This supports two layouts:
Compat: This format requires a 1.75u right shift, but retains 1.25u FN keys (json data)
Narrow: This keeps more meta keys to the right of the space bar, but requires 1u FN keys (json data)
Hardware Revisions/Errata
- 1.0: Initial version (bad right arrow, not recommended) gerbers
- 1.1: Fix right arrow, change (ground short on C14) gerbers
- 1.2: Repour ground (ordered from easyeda, verified working) gerbers

Questions
How big is the R68 PCB?
It measures 304.8 × 95.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the R68 use?
164 parts, built around the ATMEGA32U4-AU, K0, K1 and K2. 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 R68 KiCad files?
From the rpedde/r68 repository on GitHub, at the commit this page was made from: the board is schematic/r68.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the R68 design in my own project?
Its repository publishes it under the GPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
