The Calliope Mini can be programmed through Microsoft MakeCode just like the 'bit, including radio communications and displaying on the 25 LED matrix! It can also run micropython code on the micro:bit - we would recommend using the default micro:bit micropython build and then using the accessories on-board as if they were wired to a 'bit on a breadboard or with alligator clips.\u003c\/p\u003e\u003cp\u003eCheck out their website for a plethora of classroom-friendly projects and experiments.
