Lagom keyboard kit (partially assembled)

70.00 inc. VAT

Lagom is an easy-to-build full featured 65% keyboard using only through hole components. Now available in black or white

It uses a separate QMK-compatible microcontroller (like the Pro Micro or Elite C) to enable flexibility in connectivity and to further simplify the soldering experience (no more soldering tricky USB ports).

This is a partially assembled kit (we used this to test our new RP2040 Pro Micro controllers and they work great!) so diodes, capacitors, ICs, OLED and a pre flashed RP2040 Pro Micro are already soldered on. You will still need to attach stabilisers, solder switches and encoders and assemble the case.


  • Flexible layout options (ANSI, ISO, 6.25u or 7u or split space, split backspace)
  • 2 rotary encoders (for things like volume, next/previous track and brush size)
  • OLED screen (for things like WPM counts and adorable cats)
  • Integrated sandwich style FR4 case (with the PCB floating between a switch plate and the base)

This kit contains most of the things that you will need to build your own mechanical keyboard and program it yourself using QMK or Vial. See what’s included and what’s not included in the description below.

What’s included:

  • Printed circuit board, base and switch plate
  • Diodes (74) – already soldered onto the board
  • Capacitors (2) – already soldered onto the board
  • IC sockets (2) – already soldered onto the board
  • ICs (SN74HC138N) (2) – already attached onto the board
  • Standoffs and screws (to build the case)
  • Rubber bumpers for the base
  • A RP2040 Pro Micro flashed with Vial firmware – already soldered onto the board
  • OLED screen – already soldered onto the board

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)
  • 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)
  • 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)

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
