InMojo Real Time Clock module with battery backup is very simple to implement and very useful in projects that require tracking the real time.

Real time clock modules are not factory programmed and battery is not inserted during shipping to prevent fire hazard.

Connect SDA, SCL lines to the respective DATA and CLOCK lines of the micro-controller and then power 3.3V/5V to VCC and GND connections. (Vcc is depend on logic voltage of your base circuit)

Check our download section below to get our Arduino Library with sample code to connect with Arduino or c source driver code to connect with Microchip PIC, dsPIC with CCS C Compiler.

1. Please note that CCS C Compiler is not provided and should be obtained from CCS Inc website
2. CR1220 battery is included with every order.

Arduino Library installation guide:
1. Open Arduino programming interface on your Mac or PC.
2. Check the default sketchbook location by opening the Preferences tab (File > Preferences).
3. Create a Directory called "libraries" under the sketchbook directory and copy the folder "DS1340Z".
4. Restart Arduino programming interface and check File > Examples and select DS1340Z.
5. If you need just the library import, Sketch > Import Library and select DS1340Z.

If you have any trouble setting up the provided driver or hardware feel free to contact us at
