SparkFun gator:science Kit for micro:bit

As part of SparkFun's gator:bit series of alligator-clippable accessories, the SparkFun gator:science Kit includes all of the current sensor-related gator:boards to get started playing with the SparkFun gator:bit ecosystem. It includes seven micro:bit accessory boards to expand the functionality & your ability to experiment right out of the box along with the latest revision of the gator:bit; an all-in-one “carrier” board for your micro:bit that provides you with a fully functional development and prototyping platform. This kit is recommended for all users, from beginners to engineers and does not require any soldering at all!

Inside this kit you will find a gator:microphone audio board, gator:UV ultraviolet sensor, gator:soil moisture sensor, gator:environment CCS811 and BME280 sensor, gator:particle biometric sensor, gator:RTC (real time clock), and gator:log data logger. Additionally, we've also included a SparkFun gator:bit V2.0, alligator cables, and a 1GB microSD card and USB adapter! This all-in-one kit makes it easy to add sensors to micro:bits in the classroom or educational setting, just add micro:bits.


The micro:bit is a pocket-sized computer that lets you get creative with digital technology. Between the micro:bit and our shield-like bit boards you can do almost anything while coding, customizing and controlling your micro:bit from almost anywhere! You can use your micro:bit for all sorts of unique creations, from robots to musical instruments and more. At half the size of a credit card, this versatile board has vast potential!


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

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

2 Programming

Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

2 Electrical Prototyping

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.
