Macro Keyboard with Encoder

If you found my things useful, you can buy me a cup of coffee: http://paypal.me/marcuss24

There are two versions of Knob, the first one is in one piece and the second one is splited in 3 parts. They have to be glued together. Multipart knob is prepared for encoder LED backlight. The middle part should be printed from transparent filament, I suggest to use transparent PMMA.

Required parts:

• 8pcs Kailh 1350 - Low Profile Switch
• 1pc Arduino Pro Micro
• 1pc USB C Female connector on PCB
• 1pc micro USB male connector
• 1pc Rotary Encoder KY-040
• 5pcs 3mm heat set inserts (for back cover)
• 5pcs M3 x 8 mm flathead screws (for back cover)
• 2pcs 2,5 x 6mm screws (for encoder)
• wires

Keycaps can be 3D printed, Stephan Park made them and he uploaded them on GrabCAD site: https://grabcad.com/library/kailh-lp-choc-pc-keycap-1

Optional parts - for LED RGB backlight:

• 12pcs W2812 2020 LEDs (1 for each key and 4 for the encoder)
• 1pc resistor 470Ω (between Arduino LED control pin and LED data/signal pin)

It was designed for tight fit, so your printer has to be calibrated, otherwise switches won't fit.
