What’s included:
- Printed circuit board, base and switch plate
- Diodes (74)
- Capacitors (2)
- IC sockets (2)
- ICs (SN74HC138N) (2)
- Standoffs and screws (to build the case)
- Rubber bumpers for the base
What’s not included (and you’ll need you source yourself):
- MX compatible switches (3 pin or 5 pin, up to 72 of them depending on the layout)
- A controller (Lagom supports Pro Micro, Pro Micro USB-C, or compatible footprint controllers like the Elite-C, Nice!Nano, or RP2040 based controllers with a Pro Micro footprint)
- Keycaps
- PCB mount stabilisers (for bigger keys like Space and Shift, the amount you need depends on the layout you go for, a regular space bar requires 6.25u stabs, a 7u requires 7u stabs and a split bar requires 2 x 2u stabs)
- OLED screen (we sell these here)
- 2 Rotary Encoders (we sell these here)(and rotary encoder knobs)
- RGB light strip (optional, but possible to add a WS2812b light strip under the PCB for extra glow)
- Mill-max sockets (optional, we sell them here, if you want to make your keyboard switches hot swappable, then you can solder the sockets in and then hot swap switches)
What tools and equipment will you need to build this keyboard:
- A soldering iron
- Solder
- Flux (optional but recommended)
- Flush cutter pliers
- A small amount of electrical tape
Supported layouts:
Supported layouts include:
- Regular caps lock or stepped caps lock
- ANSI (with 2.25u left shift, 2.25u enter and 1.5u pipe) or ISO (with split left shift (1.25u + 1u) and ISO enter key)
- Regular 2.25u left shift or split left shift (1.25u + 1u)
- Regular 2u Backspace or split backspace (1u + 1u)
- Bottom row options:
- 1.25u, 1.25u, 1.25u, 6.25u space, 1.25u, 1.25u
- 1.25u, 1.25u, 1.25u, Split space (2.25u + 1.25u + 2.75u)
- 1.5u, 1u, 1.5u, 7u space, 1.5u
- Two rotary encoders or optionally 2 switches in their place
