How do I build a mechanical keyboard?

Building a custom mechanical keyboard with Modo takes 3-5 hours. Here's the complete process:

Step 1: Generate Your Design (5 minutes)

Tell Modo what you want:

"A 60% mechanical keyboard with hot-swap sockets, USB-C, and per-key RGB"

Modo generates:

• Parts list with switches, controller, LEDs
• 3D printable case files
• Wiring diagram
• QMK firmware
• Assembly instructions

Step 2: Order Parts (~$60-100)

Core Components:

• Microcontroller (Pro Micro or RP2040): $8-15
• Hot-swap sockets (Kailh or Mill-Max): $15-25
• Diodes (1N4148): $3-5
• USB-C breakout: $3-5
• Stabilizers: $10-15

Optional:

• RGB LEDs (WS2812B): $10-15
• OLED display: $5-10

You'll Also Need:

• Switches (your choice): $20-40
• Keycaps: $15-50

Parts arrive in 2-5 days from DigiKey.

Step 3: 3D Print Case (6-10 hours)

• Download STL files
• Print case bottom (4-6 hours)
• Print case top/plate (3-5 hours)
• Use PLA or PETG filament

Step 4: Build the Keyboard (2-3 hours)

1. Install hot-swap sockets on PCB or plate
2. Solder diodes (if not using integrated PCB)
3. Wire the matrix following the diagram
4. Connect USB to microcontroller
5. Test with multimeter before powering

Step 5: Flash Firmware (15 minutes)

• Compile QMK firmware
• Flash using QMK Toolbox
• Test every key

Step 6: Final Assembly (30 minutes)

• Insert switches into hot-swap sockets
• Add keycaps
• Attach case halves
• Done!

Tips for First-Time Builders:

✅ Start with a hot-swap design (no soldering switches) ✅ Test the matrix before closing the case ✅ Use a switch opener for bad switches ✅ Consider a smaller layout (60%) for first build

Cost Summary:

Compare to pre-built custom: $200-400
