BBC Micro:Bit V2.2
The Micro: Bit V2.2 Development Board has many features and is fully programmable. Each of its LEDs can be programmed individually. It is also equipped with a MEMS microphone, speaker and touch sensitive logo. It is equipped with a 2.4GHz micro: bit radio and BLE Bluetooth 5.0 if you want to realize wireless projects. It also has 25 red LEDs that can flash messages and two programmable buttons that can be used to control games or pause and skip songs in a playlist. The micro: bit V2.2 can also detect motion and tell you which direction you're going with the help of the built-in accelerometer.
You can encode, customize and control micro: bit to bring your digital ideas, games and applications to life. Measuring 4cm by 5cm and designed to be fun and easy to use, users can create everything from games and animations to floating stories, using micro: bit at school, at home and on the go.

Loudspeaker: A speaker is added to the back of the board, but you need to carefully check that the accessories are mounted closer to the panel than the depth of the existing JST connector. By default, the micro: bit sends audio to both the edge connector pins and the built-in speaker. If your accessory uses a speaker, you may want to disable the built-in speaker. This will need to be done in software.
Microphone: The addition of a rear mounted MEMS microphone with an audio input hole with a microphone LED on the front of the board. Make sure not to cover the microphone and microphone LED when mounting on accessories.
Touch Sensitive Logo: Capacitive touch support has been added to the micro: bit logo made of gold plated copper. Capacitive touch is used for large pins in micro: bit V2.2 as opposed to resistive touch found in micro: bit v1.5.
Antenna Changing the position of the antenna at an angle and plated with copper to make it more visible. If your accessory uses radio or Bluetooth, it's better to test your software packages with both card revisions.
I2C Bus: Adding special external I2C lines from nRF52 of micro: bit V2.2 for use with accessories as opposed to the shared I2C bus on micro: bit v1.5
Power: micro: bit V2.2 can be powered from two lozenge shaped pads and 3V / GND pins on the back of the board. NRF52 provides 300mA to drive the card. 100mA is reserved to power on-board components. Then 200mA is available for accessories.
MakeCode Extensions: If your MakeCode extension uses mBed or DAL, you may need to revise them to be compatible with both CODAL and revisions of the card. The latest revision no longer uses mBED.
Python Modules: Helps you have more space to build Python modules to work with additional memory, accessories, and micro: bit.
