NeoKey Socket Breakout Board – DIY Mechanical Keyboard Switch

Build Your Perfect Custom Keyboard with the NeoKey Socket Breakout Board

The NeoKey Socket Breakout Board is the ultimate DIY component for mechanical keyboard enthusiasts. Featuring a Kailh hot-swap socket, this breakout board lets you plug in any MX-compatible switch without soldering — making it incredibly easy to swap, test, and customize switches to your heart's content. A small dot of hot glue or epoxy keeps your switch firmly in place once you've found your perfect fit.

Made in Mainland China.

Key Features

• Kailh Hot-Swap Socket: Compatible with all MX-style mechanical switches — no soldering required for switch installation.
• Built-in 1N4148 Signal Diode: Placed in series with each switch to eliminate ghosted key presses in key-grid matrix configurations.
• Reverse-Mount RGB Pixel: Each board includes a single reverse-mount LED pointing upward through the switch LED window, fully chainable with In/Out pins for easy daisy-chaining across multiple boards.
• Flexible 0.1" Grid Pin Layout: Two rows of 5-pin contacts on both sides for maximum wiring flexibility and mechanical stability.
• Chainable Design: Link multiple boards together and control them as a single LED strand — perfect for full custom keyboard builds.

Pin Breakdown

1. VDD (+) — Power pin; accepts 3–5VDC input.
2. GND (–) — Ground power connection.
3. In (I) & Out (O) — Data input and output for chaining multiple boards.
4. Switch Anode (A) — Positive side of the switch+diode. Connect to your microcontroller for pull-up, or to logic level power for pull-down configurations.
5. Switch Cathode (C) — Negative side of the switch+diode. Connect to ground for pull-up, or to your microcontroller for pull-down configurations.

Frequently Asked Questions

Q: Does the NeoKey Socket Breakout Board require soldering to install a switch?

A: No! The board features a Kailh hot-swap socket, so you can plug any MX-compatible mechanical switch directly in without soldering. For extra security, a small amount of hot glue or epoxy can be used to hold the switch firmly in place.

Q: Can I chain multiple NeoKey Socket Breakout Boards together?

A: Yes. Each board has dedicated In (I) and Out (O) pins that allow you to daisy-chain multiple boards together and control all the LEDs as a single strand — ideal for building full custom keyboard layouts.

Q: What is the purpose of the built-in 1N4148 diode?

A: The 1N4148 signal diode is placed in series with each switch to prevent "ghosting" — a common issue in key-matrix designs where unintended key presses are registered. This ensures accurate, reliable input detection across your entire keyboard grid.

Q: What voltage does the NeoKey Breakout Board support?

A: The board's VDD power pin accepts 3 to 5VDC, making it compatible with a wide range of microcontrollers including Arduino, Raspberry Pi, and other popular platforms used in DIY keyboard builds.
