README
README.mdThe SmallFry 40% Board
v0.8-v0.10
- I forget everything that I did, lots of little things
- fixed some unconnected pads (oops)
- cleaned up silkscreens again
- fixed diode pads to fit SOD-123 footprint
- fixed BOM info for components
- rounded PCB edges
- replaced slotted holes with... holes
- added Vcc and Gnd pins to LED expansion
- changed LED expansion pins to 2.54 pitch
v0.7 - 2013.10.20
- cleaned up silkscreens
- moved 'ROW5' expansion to GPIO7 (still ATMEGA32U4 pin8/PB0)
- added notes
- cleaned up and removed extra libs/mods
v0.6 - 2013.10.16
- pulled extra pin for ROW5 from ATMEGA pin 8/PB0
- changed drills for holes/slots to work with OSHpark
- added GPIO4, GPIO5, GPIO6 connectors to ATMEGA pins 26/PD6, 22/PD5, 11/PB3
- ran row and GPIO to 1.27mm headers on right-side of board for interconnect (ribbon cable spacing)
v0.5 - 2013.09.20
- added back missing slot on right side of board
- added LEDs for optional keys from v0.4

Questions
How big is the Keyboard PCB?
It measures 228 × 75.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Keyboard use?
194 parts, built around the ATMEGA32U4, LC10, LC11 and LC12. 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 Keyboard KiCad files?
From the regack/40Pct repository on GitHub, at the commit this page was made from: the board is keyboard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Keyboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask regack before reusing the design.
