micro:bit V2 Go Bundle (BBC Microbit)
Price in Sri Lanka

The BBC micro:bit V2 Go Bundle is an all-in-one introductory starter kit built around the upgraded BBC micro:bit V2 pocket-sized computer. Designed for students, educators, and makers, it makes learning coding, hardware interaction, and electronics intuitive and accessible. Powered by a 64 MHz Arm Cortex-M4 processor with an integrated floating-point unit (FPU), the micro:bit V2 features an onboard speaker, a MEMS microphone with an LED activity indicator, a capacitive touch sensor, a 5x5 LED display, motion tracking sensors, and Bluetooth 5.0 wireless connectivity.

• Display: 5x5 Red LED Matrix (25 individually addressable LEDs)
• Audio: Onboard speaker and MEMS microphone with sound level LED indicator
• Inputs & Controls: Two tactile user buttons (A/B), capacitive touch logo, reset/power sleep button
• Sensors: 3-axis accelerometer (motion/gesture), magnetometer (compass), ambient light sensing, and die temperature sensor
• Wireless Connectivity: 2.4 GHz micro:bit Radio and Bluetooth Low Energy (BLE 5.0)
• Expansion Interface: 25-pin notched edge connector with 5 large alligator-clip rings (3V, GND, 0, 1, 2)
• Expansion Buses: Dedicated I2C bus for peripherals, SPI, PWM, and GPIO channels
• Accessory Power Output: Up to 200mA available for external accessories
• Power Connectors: Micro-USB port (5V DC) and a 2-pin JST-PH battery connector (3V DC)
• Supported Programming Environments: Microsoft MakeCode (Block-based), Python, Scratch, C++

Hardware and Interface Guide

• 5x5 LED Matrix: Displays scrolling text, custom icons, numbers, and basic pixel art animations.
• Touch-Sensitive Logo: Capacitive sensor located on the gold micro:bit logo, acting as an extra programmable input.
• Large Alligator-Clip Rings:
  • 0, 1, 2: Primary digital/analog input/output rings for quick connection using alligator clips or 4mm banana plugs.
  • 3V: 3V power output ring for powering external sensors and LEDs.
  • GND: Common ground reference ring.
• Micro-USB Port: Used for flashing program code, serial communication, and 5V power supply input.
• JST-PH Port: 2-pin polarized 3V DC battery input connector (matches standard 2x AAA battery packs).

Key Features

• Built-in Sound and Sensing: Create sound-reactive projects and produce musical tones directly on the board without needing external buzzer breakouts or breadboards.
• Full Motion & Direction Sensing: Integrated 3-axis accelerometer and magnetometer detect tilting, shaking, free-fall, orientation, and compass headings.
• Beginner-Friendly Coding Platforms: Supports browser-based visual programming via Microsoft MakeCode, as well as text-based programming using MicroPython, allowing users to transition naturally from novice to advanced levels.
• Wireless Device Communication: Uses custom 2.4 GHz radio messaging to communicate directly between micro:bit boards, or BLE 5.0 to interface with smartphones, tablets, and computers.

Common Applications

• STEM & Coding Education: Teaching fundamental algorithms, variables, and logic in classrooms and coding clubs.
• Interactive Wearables: Creating pedometers, digital compass badges, and gesture-controlled wearables.
• Robotics & Smart Vehicles: Serving as the primary brain for educational robotic chassis, obstacle avoiders, and line followers.
• IoT & Remote Sensing: Building wireless environmental monitoring nodes and interactive games.

Usage Tips

• JST Connector Type: The onboard battery socket uses a JST-PH 2.0mm pitch connector, not a JST-XH 2.54mm connector. Do not force an oversized connector into the socket.
• Accessory Current Limits: The board supplies up to 200mA to external modules via the edge connector. If driving servo motors or high-draw components, provide an external power supply to avoid triggering brownout resets.
• Safe Unplugging: Grip the plastic connector shell rather than pulling on the wires directly when disconnecting cables from the JST battery port to prevent broken leads.

Package Contents Note: The current micro:bit V2 Go Bundle includes the micro:bit V2 board, a short USB cable, and a Quick Start Guide. Please note that the external AAA battery case is not included in this bundle version.
