The Octopus Button Switch Brick is a simple, plug-and-play pushbutton module from the ElecFreaks Octopus Electronic Bricks series. It features a large button with a transparent cap — you can insert a custom label underneath for easy identification in your projects.
Designed for breadboard-free connections, it uses a 3-pin buckled wire connector that plugs directly into sensor shields, the OCTOPUS:BIT expansion board for micro:bit, and other compatible development boards including Arduino, Freaduino, STM32, and ARM-based MCUs.
Key Features
- Large Button with Transparent Cap – Easy to press, with space for a custom label underneath
- 3-Pin Connector – Buckled wire interface for secure, breadboard-free connections
- Plug and Play – No soldering required; connects directly to sensor shields and expansion boards
- Wide Compatibility – Works with Arduino, micro:bit (via OCTOPUS:BIT), STM32, AVR, and ARM boards
Pin Definition
- Pin 1 – Signal output
- Pin 2 – VCC
- Pin 3 – GND
Ideal For
- Beginner Arduino and micro:bit projects
- Interactive prototypes and user input
- STEM education and classroom activities
- Quick sensor shield integration without breadboards
Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- AVR
- AVR is a family of 8-bit microcontrollers (made by Microchip, formerly Atmel) used in many classic Arduino-style boards such as the Uno and Nano. They are widely supported but older, which can be a limit for memory- or speed-intensive tasks.
- GND
- GND is the ground or reference connection (0 V) for a circuit. When connecting two devices together, their grounds must be joined so both agree on what counts as a low or high signal.
- Shield
- An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
- STM32
- STM32 is a family of microcontroller chips commonly used in embedded electronics. Knowing a product uses an STM32 can help when looking at firmware updates, pin connections, or low-level serial control options.
- VCC
- VCC is the positive power-supply connection on a chip or module. Connecting it to the correct supply voltage is needed for the part to power on and helps avoid damaging the electronics.
