60% mechanical keyboard

KK_ansi60 keyboard is inspired by GH60 open source keyboard. Case and mounting plate are made from one piece of aluminium alloy. This feature allows very solid and compact design. On the other hand only ane switch layout is supported. Keyboard support TMK firmware, so everything is open source and customizable. On default there are two base layers. Active layer is indicated with LED under FN1 or FN2 key.

Build instructions

Solder all SMDs parts on PCB.
Temporary solder USB cable on connector J1.
Load firmware.
1. Plug USB cable into computer.
2. Run command dmesg, you should see Product: ATm32U4DFU in output list. If not, double check your soldering and check if you have ATMEGA32u4 with DFU bootloader.
3. Clone repo git clone "https://github.com/MarekKap/KK_ansi60".
4. Go to firmware directory cd KK_ansi60/Firmware/.
5. Compile program make.
6. Load firmware into keyboard sudo make dfu.
7. Unplug USB cable from computer.
Desolder USB cable.
Install keycaps stabilizers on top plate.
Install some switchies on on top plate. Start with edges and long keys.
Flip the top plate and put PCB on installed switches.
Cut switch legs. Keep in mind, there is only 2mm space between PCB and bottom plate.
Solder switches on PCB.
Install, cut and solder rest of the switches.
Install, cut and solder LED1 and LED2.
Remove insulation from USB cable. Use heat shring tube or your nylon cable sleeve will start stripping over time.
Use cable tie to hold USB cable in place.
Solder free USB wires to connector J1. Keep D+ and D- wires twisted as long as possible.
Hold down USB wires using kapton tape on PCB.
Install CNC legs with screws on bottom plate and put self adhesive pads in place.
Stick a insulation sticker on bottom plate (PCB side).
Screw bootom and top piece together with M2.5 screws.
Plug USB cable into computer and enjoy your keyboard. :-)
