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.
