## What it is
A build guide for the LMN-3, a DIY hardware device combining a mechanical keyboard, joystick, rotary encoders, a Raspberry Pi 4, and a Hyperpixel 4 screen. It provides a bill of materials and assembly instructions for building the device.

## Use cases
- build your own LMN-3 hardware device
- find the parts needed for an LMN-3 build
- assemble a DIY keyboard with joystick and screen
- step-by-step guide for building a Teensy and Raspberry Pi based device
- source components for a custom macro pad build

## When to choose
- you want to physically build the LMN-3 device
- you need the complete bill of materials for the project
- you are following the FundamentalFrequency LMN-3 ecosystem

## When to avoid
- you want the LMN-3 firmware or CAD files rather than assembly instructions
- you need a finished, purchasable product instead of a DIY build
- you are looking for general keyboard building guides unrelated to LMN-3

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: documentation
- domain: hardware, developer-tools, tutorials
- platform: cross-platform
- tags: build-guide, diy-electronics, lmn-3, mechanical-keyboard, raspberry-pi, teensy, hardware-project
