4 - [katy](https://deskthority.net/workshop-f7/katy-keyboard-or-k80cs-key80-contoured-split-t8524.html)
6 with the added possibility to connect up to 6 external switches like pedals,
7 and somewhat like the katy, not all keys are on the same level for easier reach.

20 There is intentionnaly no hole for the TRRS connector, you are supposed to use a drill for it.
21 This way if you don't want to use the pedals you don't have a useless hole. Plus it's cleaner.
24 You can find my original file here : http://qmk.fm/frenchdev/example_printable_stickers.svg
26 I used it when training but now I use blanks and the layout is different.
27 I still uploaded it because I think it can be a good jumpstart for any temporary stickers on the
32 - [teensy 2](https://www.pjrc.com/store/teensy.html)
33 - 3 LED, 5mm tall with flat head
37 - 1 [micro usb breakout board](http://www.ebay.com/itm/-/201387922085?)
38 - 88 cherry/gateron switchs
45 If you fancy adding pedals :
46 [these are good enough and cheap](https://www.amazon.fr/gp/product/B00V7WITKI/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1). You also need a RCA connector for each of those to replace the included cable
48 If you (or your coworkers) find them too loud you can replace the switch inside them.
49 For once we don't really care about what's inside :)

96 We use pull up resistor for SCL and VDA, see https://github.com/ErgoDox-EZ/docs/blob/master/ErgoDox%20EZ%20Schematic.pdf for example
98 The connector is a standard TRRS (jack with audio + mic)
100 Diode direction is row to column
