Features:
 All pins are brought out to 0.1" headers that are color coded black for
ground, red for power, and yellow for signal. You can breadboard easily
by matching up with these premium header jumpers
 On-board buzzer: you can use the music module in MakeCode to play
music, and now you'll get audible beeps! If you want to use headphones, a
3.5mm audio connector on the board is available as well.
 Two LEGO-compatible pin holes for easy assembly and integration.
 5 x alligator clip gold pads, the same as the ones on the micro:bit
 USB connector with on/off push button switch so you can turn projects on
and off - the micro:bit doesn't have a switch which means unplugging
instead, this is easier!
 Includes 1A self-recovery fuse to help keep your projects protected
