1 # Frenchdev : My take on a splitted keyboard for dev and french language
3 - [ergodox](https://ergodox-ez.com/)
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.

11 - [editable layout on keyboard layout editor](http://www.keyboard-layout-editor.com/#/gists/4480e3ab8026eb7c710a7e22203ef4aa) (keys placement is NOT precise on this)

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.

25 You can find my original file here : http://qmk.fm/frenchdev/example_printable_stickers.svg
27 I used it when training but now I use blanks and the layout is different.
28 I still uploaded it because I think it can be a good jumpstart for any temporary stickers on the
33 - [teensy 2](https://www.pjrc.com/store/teensy.html)
34 - 3 LED, 5mm tall with flat head
38 - 1 [micro usb breakout board](http://www.ebay.com/itm/-/201387922085?)
39 - 88 cherry/gateron switchs
46 if you fancy adding pedals :
47 [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
49 If you (or your coworkers) find them too loud you can replace the switch inside them.
50 For once we don't really care about what's inside :)
54 The PHYSICAL rows and columns are connected as such :
56 on right hand (slave) :
60 GND -| 1 VSS \_/ NC 28 |
62 R5 -| 3 B0 A6 26 |- C14
63 R4 -| 4 B1 A5 25 |- C13
64 R3 -| 5 B2 A4 24 |- C12
65 R2 -| 6 B3 A3 23 |- C11
66 R1 -| 7 B4 A2 22 |- C10
67 R0 -| 8 B5 A1 21 |- C9
70 VCC -| 11 VDD INTB 18 |
72 SDA -| 13 SDA RST 16 |- VCC
73 | 14 NC ADDR 15 |- GND
76 and on left hand (main) :
97 We use pull up resistor for SCL and VDA, see https://github.com/ErgoDox-EZ/docs/blob/master/ErgoDox%20EZ%20Schematic.pdf for example
99 the connector is a standard TRRS (jack with audio + mic)
101 Diode direction is row to column
