This little board allows you to control and power up to 16 servos at the same time with a BBC micro:bit!
The servo power connections (typically 5V) can be made through the USB connector or the 2-pin screw terminal or by using the 2-pin male header. The extension even allows you to control the speed of servo rotation to make your models move extra smoothly!
