This listing is for a set (top + bottom) Case / Plates

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 is a fully programmable 58-key split, ortho-columnar keyboard with a 4x6 main matrix and 4+1 thumb-keys per hand, supporting up to two OLED screens and two rotary encoders (one each per hand).

• Layout very similar to the original Lily58 family which this is derived from
• QMK and VIAL 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 (optional SMD addons)
• Reversible PCB design, the PCB for both hands are identical
• Each hand can be used separate as a gamepad keyboard/device
• Hands are connected using serial link (TRRS or USB type C)
• Each hand uses an Pro Micro Arduino clone as the controller (Pro Micro or pin 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 ESD protection on link connection

Sandwich Case plates

Top Plate (Three alternate versions)

• OLED Top Plate - Support for mounting an 0.91" OLED screen - NOTE! This does NOT fit a nice!view screen on Lotus 58 - BLE.
• Encoder Top Plate - Support for mounting a Rotary encoder in the upper position.
• Blank Top Plate - Blank plate with no mounting hole for a screen or upper encoder.

• Coming Soon! nice!view Top Plate - Suitable for the Lotus 58 - BLE Version and a nice!view screen.

  Bottom Plate (Two alternate versions)

• Standard Bottom Plate - Standard bottom plate for a 'low profile' build.

• Tent/Tilt Bottom Plate - Bottom plate with three mounting ears (⌀3 mm hole) to support tenting and tilting your keyboard. (Req. additional hardware)

Mounting Hardware Kit

The parts needed for assembling the case.

• 5x brass spacers (M2).
• 10x countersunk hex head bolts (M2 x 4 mm)

Versions

v1.0 - The original design had breakaway parts for the switch holes, allowing the front plate to be used as a backplate.

v1.1 - Updated version with no breakaway parts, adding the blank option, and tentable bottom plates (⌀3 mm hole).

v1.2 - Adjusted fit on OLED cutout, Encoder and tenting plates are updated to a ⌀4 mm hole. No copper layer for better wireless performance.

Normal handling time is 3 - 5 working days, not including build items (Those usually take 1 - 2 weeks).

Shipping is done with insured/signed for parcels, where no such service is available the parcel is sent as insured parcel, but may not be fully traceable the entire transit. If no insured or traceable service is available, parcels will be sent as uninsured/untraceable at the buyers responsibility. All of which is clearly stated on checkout.

All packets are represented to courier services and customs at their true sale value, and all responsibility for import fees, taxes and tariffs lie with the buyer.

The SE/EU "Act on Distance Contracts and Off-Premises Contracts (SFS 2005:59)" allows returns of the items in undamaged (unsoldered!) condition within 14 days of receiving it. Return shipping on returned items are the responsibility of the buyer.
