The very Christmas-y Elecfreaks Snowflake Buzzer is a speaker that lets you program your micro:bit to sing beepy Christmas carols!

Also available in a bundle with the Elecfreaks Rainbow Christmas Tree to make the merriest of micro:bit displays!

It connects with alligator clips, no soldering required! The clips attach through holes so that the wires are out of sight behind the snowflake.
