• New BBC micro:bit V2 adopts faster ARM Cortex-M4 nRF52833 processor, integrates 2.4G Radio/BLE Bluetooth 5.0, now includes built-in MEMS microphone, speaker, and touch sensitive logo pin, enabling people to get creative more easily through sound and touch sensing.
• Micro:bit V2 has a motion sensor which combines 3-axis sensing accelerometer, together with magnetometer that can be used as compass or magnetic field strength sensor.
• Memory has increased by 700% from 16KB to128KB RAM and 256KB to 512KB flash which gives the device much more capability.
• The CPU has been upgraded from a Cortex m0 at 16MHz to a Cortex m4 with a floating-point at 64MHz.
• The golden edge connectors have small indentations that allow much easier prototyping with crocodile clips that won’t keep falling off.
• The board can now provide 200mA to accessories, up from 90mA in the previous board version.
• Extra input capability is achieved with the touch sensor to accompany the existing two buttons.
• Version 2 now has a power LED and can be switched off instead of having to remove batteries.
• Able to support both AI and machine learning.
