YUIOP Keyboard series

YUIOP keyboards are experimental original keyboards designed by KoRoN.

Keyboards in this project are:

• yuiop27/ - separate keyboard prototype.

  27 keys for one hand. single left hand.

• yuiop54/main - signle board keyboard prototype.

  combined right and left-hand boards of yuiop27. PCB dimension is 285.00mm x 94.60mm (GH60 compatible form factor without screw holes).

• yuiop54/main2 - researching version of yuiop54.

  multi-sheets schematic. fix layout for auto routing. introduce GND cupper fill.

  • rev.B - trial to make compatible with GH60 (include screw holes).

    use popular keycaps size. tring 128x64 dots OLED.

  • rev.C - key sizes revised version.

    consider just layout. use 1u footprint for keys of little fingers. compact form factor size, 267.00mm x 95.00mm (drop compatibility with GH60). change the origin to center of PCB. use 2u for R5 center key. use Edge.Cuts to represents screw holes. OLED is 128x32 dots.

  • rev.D - narrowwer version of rev.C

    consider just layout. the dimension is 262.0mm x 95.00mm reduce margins between F and G keys, and H and J keys.

  • rev.E - a variation of rev.C

    the dimension is 267.00mm x 95.00mm (same with rev.C, not rev.D) make keys on F's row be able to use 1.25u keycap.

• yuiop47/ - Single board keyborard with 47 keys.

  Shrink from yuiop54. PCB dimension is 214.00mm x 94.00mm

• yuiop60hh/main - HHKB clone trial

• yuiop60hh/main2 - HHKB clone trial #2

• yuiop50d/ - Small footprint, dense 50 keys keyboard.

  1u is 16mm, using small keycaps. Standard row staggered layout. Support Pro Micro and RapsberryPi Pico as MCU. PCB dimension is 182.00mm x 103.50mm

• yuiop63hhs/ - Split HHKB layout minimal keyboard.

  No LED nor OLED, Just 63 (29+34) keys. PCB dimension 319.00mm x 95.00mm

  • Left 152.50mm x 95.00mm
  • Right 162.00mm x 95.00mm

• yuiop22rs/ - 22 keys + rotary switch macropad.

  With OLED, without LED. PCB dimension 95.25mm x 95.25mm

• contorller/ - Keyboard controler using ATmega32U4 which replacing Pro Micro.

• yuiopPM/ - Pro Micro compatible but minimal for only keyboard, PCB

• yuiop60hh/main3 - HHKB layout, compatible with popular 60% cases.

  Problems on positions of screw hole or so. Not built.

• yuiop60hh/main4 - HHKB layout, compatible with popular 60% cases.

  YUIOP60HH series revision 4. Implemented with MPU ATmega32U4 (not Pro Micro)

• yuiop31rs/ - 31 keys + rotary switch macropad.

  With 31 LEDs (WB2812C-2020). Its hole is too small to be chaged extra on production.

• yuiop60s/ - split keyboard prototype

• yuiop60pi/ - PGA2040 (RP2040) base HHKB layout semi-compatible keyboard.
