Basic:bit is a basic breakout board of micro:bit. It carries a buzzer and three groups of GVS pins(P0/P1/P2) on board. Each group of GVS pins separately leads out the IO port, 3V port and GND port on micro:bit. Small size with simple structure, it is quite enough for you to complete 98% micro:bit projects.
Features
Small size with smart design, it is a perfect match for your micro:bit.
Easily connected to micro:bit and lead out its power and IO ports with screws only.
Lead out P0/P1/P2/3V/GND port on micro:bit board.
Allow you to complete 98% micro:bit projects with three IO ports.
The switch on board controls the ON/OFF status of buzzer.
Quick Start
Material Needed:
1 x micro:bit
1 x basic:bit
1 x Octopus LED Module
1 x USB Cable
1 x GVS wire（Or Jumper Wire)
Assembly
Fix your basic:bit onto micro:bit with screws and nuts.
Connect Octopus LED module to P1 port on your basic:bit.
Then slide the switch to the speaker end.
Example Code

After saving the above code into micro:bit, the buzzer starts to play the music again and again. At the same time, Octopus LED module twinkles with 1 second space.
Parameter
Voltage: 3.3V （Powered by micro:bit）
IO Ports: 3
Dimension: 51.7mm x 29.1 mm

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.
