Raspberry pi DS1307 RTC Module

SKU: DFR0386

The RTC module is specifically designed for Raspberry Pi. It communicated with Raspberry Pi through I2C bus. There is a Maxim DS1307 and CR1220 button cell on the board to keep the real time for a long time after the Raspberry Pi has it's powerdown. Set a serial port, TTL convenient way online debugging.

    FAQ

    • Hello,

      I have bought 4 RTC modules from DF robot and they have safely arrived last Friday.

      I would like to use the RTC for Arduino also. May I know which pins are used in the RTC module to power it up, communicate to MCU and etcetra.

      Hope you can assist me by giving the pin assignment for the RTC module.

      By the way, can the battery be inserted in the RTC module when it is connected to the Raspberry Pi/Arduino?

      Thank you,

      Intern USMC

      You can check the dimension of the module from the wiki, I think the pins you need are VCC/GND/TX/RX. You'd better insert the battery before inserted in Pi
