Micro:bit V2 Board DIY development board Pocket-size Computer Kit. with speaker, microphone, accelerometer, 2.4GHz radio/ BLE 5.0

The new micro:bit V2 brings new onboard features and upgrades Compatible with all the existing lessons, code and most add-on boards.

Features:

  • 64 MHz Arm Cortex-M4 with FPU
  • 512KB Flash
  • 128KB RAM
  • 5×5 Red LED Array
  • Two Programmable Buttons, one touch sensitive logo
  • MEMS microphone and LED indicator
  • Onboard Light, Compass, Accelerometer, Temp Sensors and Speaker
  • 2.4 Ghz Micro:bit Radio/BLE 5.0 Smart Antenna
  • 25-pin Edge Connector
  • 4 dedicated GPIO, PWM, I2C, SPI, and ext. power
  • Three Digital/Analog Input/Output Rings
  • Two Power Rings — 3V and GND
  • Dedicated I2C bus for peripherals
  • MicroUSB Connector (5V)
  • JST-PH Battery Connector (Not JST-XH) (3V)
  • Power/reset Button with Status LED
  • 200 mA available for accessories
  • Program with C++, MakeCode, Python, Scratch

New Features (exclusive to the micro:bit v2)

  • On-board speaker
  • MEMS Microphone with LED indicator
  • Touch sensitive Logo
  • Built in sleep/off mode (enabling the board to be powered down whilst batteries remain connected)
  • Discreate regulator (to supply up to 200mA of current to external accessories)

Micro:bit V2 Board DIY development board Pocket-size Computer KitRefinements

  • Notched edge connector
    • This will make connecting things (such as crocodile clips and conductive thread) easier
  • Power LED indicator
    • In addition to the USB activity indicator, the power LED shows whether the micro:bit is powered on or off
  • Copper plated antenna
    • This will allow for easier identification for the radio/bluetooth component
  • Memory has increased from 16KB to 128KB RAM and 256KB to 512KB flash
    • This gives the device much more capability
  • The board can now provide 200mA to accessories
    • This has increased from 90mA in micro:bit v1
  • Extra input capability is achieved with the touch sensor to accompany the existing two buttons

How to use the new features

  • On-board speaker
    • The Speaker will work in the same way you would expect when you connect headphones or an external speaker to the micro:bit
    • By default, the sound output will be on both the speaker and Edge connector
  • MEMS Microphone with LED indicator
    • The microphone has an additional set of blocks in MakeCode and objects in MicroPython to use, that can monitor and record sound
  • Touch sensitive Logo
    • The logo touch is implemented in the same way as touching a pin on the edge connector and will have equivalent blocks in MakeCode and objects in MicroPython to use

Features that are common to all board variants will work in the same way as on the BBC micro:bit v1. For example, you will be able to use the same blocks in MakeCode to use the accelerometer on any board revision

All they key enabling software for using the device, including the new features has been developed in conjunction with Lancaster University in the CODAL runtime, a successor to micro:bit-dal which was used on micro:bit v1
