SparkFun gator:RTC - micro:bit Accessory Board

The SparkFun gator:RTC is an integral part of the gator:bit series of gator-clippable accessories, designed for seamless interaction with the micro:bit or other microcontrollers. This data logging tool allows students to focus on the experiment at hand without the need to constantly monitor a thermometer or stopwatch. The gator:RTC is powered by the RV-3028 real time clock (RTC) module from Micro Crystal, which operates via a convenient I²C bus interface. This module tracks the year, month, date, weekday, hours, minutes, and seconds. It also incorporates an external event input with a time stamp function. The gator:RTC is extremely energy-efficient, operating at about 40-60nA at 3V. It features four pads for power and data and includes a built-in, rechargeable 3V lithium coin cell battery.

The micro:bit is a compact, pocket-sized computer that unlocks a world of creative possibilities with digital technology. Together with our shield-like bit boards, the micro:bit allows you to code, customize and control your device from almost anywhere. This versatile board, half the size of a credit card, can be used to create anything from robots to musical instruments, and much more.

The gator:RTC is equipped with several features that make it a valuable addition to any project. It houses the RV-3028 RTC module that features an I²C bus interface and tracks a variety of time units. It also includes an external event input with a time stamp function and operates at a low power of 40-60nA at 3V. The gator:RTC also includes four pads for power and data and a rechargeable 3V lithium coin cell battery.
