This is straight forward fairly basic expansion board for micro:bit, yet it is so useful! It carries a buzzer and three groups of GVS pins(P0/P1/P2) on board. Each group of GVS pins separately leads out the IO port, 3V port and GND port on micro:bit. Small size with simple structure, it is quite enough for you to complete 98% micro:bit projects.
Note: This is the basic:bit board only, please get the micro:bit here.
