SparkFun gator:bit

The SparkFun gator:bit is a comprehensive carrier board for your micro:bit, offering a fully-developed platform for prototyping and development. This board breaks out nearly every pin on the micro:bit to pads that are compatible with alligator clips, maximizing the utility of your micro:bit. With the SparkFun gator:bit, you can visualize data using the five onboard addressable LEDs, sense capacitive touch on pins 0, 1, & 2, or even create musical compositions with the integrated speaker.

The SparkFun gator:bit provides safe access to as many GPIO as possible from the micro:bit. Pins 0, 1, 2, 8, 16, 5 (Button A), and 11 (Button B) are broken out and protected against overvoltage and overcurrent/short circuit. Pins 0, 1, and 2 are ADC pins and also function as capacitive touch pins. Pins 8, 16, 5, and 11 are digital pins, capable of read and write functions. Additionally, pins 13 (SPI), 14(SPI), 15(SPI), 19 (I²C), and 20 (I²C) can be used to read and write a variety of digital signals. More detailed information about each pin and other attributes can be found in the SparkFun gator:bit Guide.

The SparkFun gator:bit can be powered from 2.7V - 9V, offering a wide range of powering options. Power can be supplied either from the JST battery terminal or the alligator clip pads labeled “VIN”. Any voltage input between 2.7V and 9V will be regulated to 3.3V to power the micro:bit, the speaker, and any of the alligator clip pins.

Even without any external hardware, the gator:bit serves as a comprehensive development board for the micro:bit. It provides easy access for educators, beginners, and professional makers.

The micro:bit is a compact computer that lets you explore digital technology creatively. With the micro:bit and our shield-like bit boards, you can code, customize and control your micro:bit from almost anywhere! The micro:bit can be used for a multitude of unique creations, from robots to musical instruments and more. Despite being half the size of a credit card, this versatile board has enormous potential!

Note: The SparkFun gator:bit does NOT include a micro:bit board. The micro:bit will need to be purchased separately.
