SparkFun gator:RTC - micro:bit Accessory Board

The gator:RTC is a supplemental data logging tool to be used in conjunction with the gator:log, part of SparkFun's gator:bit series of gator-clippable accessories designed for easy interface with the micro:bit or other microcontrollers. This tool allows a student to focus more on the experiment than watching a thermometer or stopwatch.

At its core is a RV-3028 real time clock (RTC) module from Micro Crystal, using a convenient I²C bus interface. The module enables you to track the year, month, date, weekday, hours, minutes, and seconds. It also includes an external event input with a handy time stamp function. It is extremely low power, running at about 40-60nA at 3V. The gator:RTC provides four pads for power and data and a built-in, rechargeable 3V lithium coin cell battery.


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!

The BBC micro:bit is a compact, powerful programming tool that requires no software installation. Read on to learn how to use it YOUR way!

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.
