Grove - DS1307 RTC (Real Time Clock) for Arduino . Grove - DS1307 RTC is based on the clock chip DS1307 and supports I2C communication! It uses a Lithium cell battery (CR1225). We choose to use the RTC based on DS1307 as it is low cost and also very energy efficient. It can run for years on a very small coin cell. (Seeed SKU 101020013)
