BBC Micro:Bit V2.2
The Micro:Bit V2.2 Development Board is equipped with many features and is fully programmable. Each of its LEDs can be programmed individually. It also comes with a MEMS microphone, speaker, and touch-sensitive logo. For wireless projects, it's equipped with 2.4GHz micro:bit radio and BLE Bluetooth 5.0. It also has 25 red flashing LEDs 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 with the help of its built-in accelerometer, it can tell you in which direction you are going. With Micro:Bit, you can code, customize, and control your digital ideas, games, and applications. Measuring 4 cm by 5 cm, and designed to be fun and easy to use, users can create anything from games and animations to scrolling stories, both in the classroom, at home, or on the go.
Speaker: A speaker has been added to the back of the card, but you should carefully check that the accessories are mounted closer to the panel than the depth of the available JST connector. By default, the micro:bit sends the sound to both 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: A MEMS microphone with a sound input hole and a microphone LED has been added to the back of the card, mounted on the front. Make sure that when mounting the accessories, the microphone and microphone LED are not turned off.
Power: Micro:bit V2.2 can be powered from two coin-shaped pads on the back of the card and the 3V/GND pins. The nRF52 provides 300mA to run the card. 100mA is allocated to provide power to the built-in components, and 200mA is then available for accessories.
MakeCode Extensions: If your MakeCode extension uses mBed or DAL, you may need to revise them to be compatible with both revisions of the card and CODAL. The latest revision no longer uses mBed.
Python Modules: The added memory can help you create Python modules to work with your accessories and micro:bit.
