Robotbit IOBIT V2.0 Micro:bit Expansion Board

The IOBIT V2.0 Micro:bit Expansion Board is a compact KittenBot breakout board for the BBC micro:bit. Plug the micro:bit into its edge connector and every programmable pin is brought out to 2.54 mm headers with colour-coded ground, power and signal pins, so you can connect sensors, servos and modules with ordinary jumper wires. It also adds a buzzer, an audio jack, a power button and fuse protection, which makes it handy for classrooms and beginner projects.

What's in the Box

• 1 × IOBIT V2.0 expansion board (micro:bit not included)

Tip: Keep the total load on the 3 V and 5 V outputs under 1 A; a few small servos are fine, but larger motors need a separate driver and supply. Pins 19 and 20 are used for I2C, and some other pins are shared with the micro:bit LED display, so disable the display in code when you use them.
