This listing is for a single (1 pcs) Lotus 58 Glow - PCB version 1.23

Please note that this makes a single hand/side of the keyboard, a complete keyboard requires 2 sets of PCB's and (additional) components.

Build your own ergonomic keyboard!

Lotus 58 Glow is a fully programmable 58-key split, ortho-columnar keyboard with a 4x6 main matrix and 4+1 thumb-keys per hand. Optional support for one OLED screen per hand/side showing information such as active layer, CapsLock/NumLock etc. as well as one Rotary Encoder per hand, with optional placement.

  • Layout very similar to the original Lily58 family which this is derived from
  • QMK compatible, fully programmable keyboard
  • Kaihl Hot-swap sockets for Cherry MX compatible switches (3&5-pin)
  • All components through-hole and easily soldered for beginners
  • Reversible PCB design, the PCB for both hands are identical
  • Hands are connected using serial over TRRS-cable
  • Each hand uses a Pro Micro Arduino clone as the controller (Pro Micro/Elite C and equivalent)
  • Designed with a sandwich-style plate/case as part of the design
  • Basic build instructions are printed on the PCB for an easy build
  • Support for battery cut-off switch for wireless builds (nice!nano or equivalent)

Optional Features

(These requires additional components)

  • Optional OLED Screen (one per hand)
  • Optional Rotary Encoder (one per hand)
  • Optional RGB Underglow (6 SK6812 mini RGB LED's per hand)
  • Optional per-key adressable RGB (29 SK6812 mini-E RGB LED per hand)

Please view image above for a visual representation on OLED/Encoder placement.

Sandwich Case plates

Top Plate (Three alternate versions)

  • OLED Top Plate - Support for mounting an 0.91" OLED screen
  • Encoder Top Plate - Support for mounting a Rotary encoder

Bottom Plate (Two alternate versions)

  • Standard Bottom Plate - Standard bottom plate for a 'low profile' build.
  • Tent/Tilt Bottom Plate - Bottom plate with mounting ears to support tenting and tilting your keyboard. (Req. additional hardware)

Additional Component Kits

Basic Component Kit

Through hole type diodes are the most beginner friendly.

  • 1N4148 diodes (29 + 1 pcs / PCB)
  • 3.5 mm 4-pole TRRS Socket (1 pcs / PCB)

Basic Component Kit SMD

SMD diodes are recommended for more advanced builders only but give a sleeker PCB.

  • Kailh (Cherry MX) Hot-Swap Sockets (29 pcs / PCB)
  • 1N4148 diodes (29 + 1 pcs / PCB)
  • 3.5 mm 4-pole TRRS Socket (1 pcs / PCB)

Components NOT available in this shop!

I basically will take apart anything to find out how it works!
And sometimes I even get around to putting it back together again. More or less the same as before. Sometimes. Maybe... Well, I did it once at least!
The above applies to motorcycles, cars, computers of all sorts, and pretty much whatever mechanical or electric contraption I can get my hands on. Likes to play with multirotors, and recently for whatever reason I decided to build myself a SOF kayak.
So yeah, go ahead and figure out the common thread there if you can!
