As detailed on Microbit.org, The new BBC micro:bit is a more powerful device combining all the same features of the original and adding built-in microphone, speaker, capacitive touch sensor, and power save button. The latest developments also provide an updated technical platform designed to provide capabilities for introducing future projects that will allow future AI and ML education projects in schools.
Any programs you create that use the original micro:bit features will work on your original and new version of the micro:bit, though of course you’ll need to connect headphones or a speaker to the original micro:bit to hear any sound!
