DS1307 칩셋은 널리 사용되는 리얼타임클럭입니다.

1225 사이즈의 코인셀 배터리를 사용하며 41mAh를 사용할 경우 최소 9년정도 사용이 가능합니다.

I2C를 이용하여 값을 출력해주며 내장 I2C EEPROM(24C32)와 DS18B20 센서가 내장되어 있습니다.

I2C EEPROM은 MCU의 자원을 많이 소모하지 않고 쉽게 센서값을 저장할 수 있도록 해주며 DS18B20은 프로젝트에서 온도 모니터링에 사용할 수 있습니다. 


INTRODUCTION

After several months of "Out of Stock", DS1307 RTC module has experienced a huge upgrade. It comes with a Gravity IIC interface.Its size is also reduced to fit miniaturization application. Gravity I2C DS1307 RTC module is a easy-to-use Real Time Clock module. It is cheap and affordable in most applications such as time clock, data logger, etc. The new version DS1307 RTC module adopts high precision crystal oscillator which reduces time error dramatically. The test conducted shows the time error is only about 1 second in 24 hours (the average time error of Mechanical Watches is about 20s). The module is powered by single cell CR1220 (service life: 3~5 years). It is smaller and keeps EEPROM 4KB ROM to record information related to alarm clocks and events. Besides, you can set the IIC address by resistance adjustment. The Gravity DS1307 RTC module uses Gravity I2C interface and you can plug it on the DFRobot Gravity IO expansion shield directly. Cooperate with Arduino DS1307 library developed by DFRobot, it is easy to realize functions like setting time and time display. It can be widely used in DA (Data Acquisition).

Note: According to the latest Air Transport Regulations, the batteries, magnets and liquids transport will be very stringent, so the cell battery CR1220 will not come with the module any more. Please buy it from the local supermarket.
