برد آموزشی میکروبیت ورژن 2.2 (BBC Micro:bit V2.2)
The BBC micro:bit, a small device (4cm x 5cm) ARM development board designed to help kids learn programming, has been updated to a new version called V2. It can be used for fun projects like making digital games, musical instruments, robots, science experiments, wearable devices, etc.
The micro:bit V2 has a faster processor called ARM Cortex-M4 nRF52833, and integrated 2.4G Radio/BLE Bluetooth 5.0. It also has a built-in MEMS microphone, speaker, and touch-sensitive logo pins for sound and touch sensing. In addition, it offers a 5x5 red LED matrix that can control each LED separately and two user buttons that can be programmed to control games or pause/skip songs in a playlist. Additionally, the device comes with a motion sensor that combines a 3-axis sensing accelerometer and a magnetometer that can be used as a compass or magnetic field strength sensor.
