A simple breakout board for 2×2 button pads with integrated LEDs. Each LED and button is brought out to side connectors, making wiring straightforward. The board also includes footprints for 1N4148 through-hole diodes to isolate switches for easier matrix decoding.
Key Features
- 2×2 Button Layout – Breaks out each LED and button to individual side connectors
- Diode Footprints – Onboard pads for 1N4148 diodes to isolate switches in a matrix configuration
- Back-Side Connectors – Soldered to the rear of the PCB to keep the button side clear
Ideal For
- Custom button pad interfaces and control panels
- LED-backlit keypad projects
- Button matrix prototyping
Tip: Trim the connector leads on the button side as short as possible to reduce pad deflection.
Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
