This a custom designed module for the DS1307 Real Time Clock. Interfacing the DS1307 with a microprocessor is simplified by using synchronous serial communication. Only three wires are required to communicate with the clock/RAM: RST, I/O (data line), and SCLK (serial clock). This test-bed code should give you some insight on how to interface the module to any microcontroller using our example software SCLK.
- Communication type: 3 Wire interface
- On board battery: 3.3V
