Gator:bit is a development board for BBC micro:bit. Almost every pin on the micro:bit is broken out to alligator clippable pads so you can get the most out of it. Gator:bit comes equipped with five addressable LEDs, a built-in buzzer (speaker) as well as a power management system that gives you access to 3.3V and 5V. Gator:bit can be powered from 2.7V - 9V giving you quite a range of powering options.

Without any external hardware Gator:bit is still an exploratory development board for micro:bit. Whether it is data visualization using the on board addressable LEDs, capacitive touch sensing on pins 0, 1, & 2, or creating musical works of art using the built-in speaker we've got it covered with the with the Gator:bit.

With some alligator clips and extra hardware you'll be able to explore inputs like sensors, potentiometers, and buttons and control outputs like lights, motors, and speakers.
