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.
