Description
What it is:
- RTCRaspi is a Real Time Clock module designed for RaspberryPi (all versions)
- based on the popular DS1307 i2C real time chip from Maxim (see datasheet here)
- It works with all DS1307 supported libraries
- DS1307 chip requires 5V, but will work with 3.3V data lines (plug an play with RaspberryPi)
- For use with ArduinoUNOs, you will need to bridge the 3.3V and 5V pins (see pinout)
- Can be used with Moteinos the same way, but you will need a 5V source to power the RTC chip
- May come in Red or Green (if you have a preference leave a comment at checkout)
What you get:
- RTCRaspi tested board
- 2x3 female double length extended header for RaspberryPi
- CR1220 coin cell
Connections:
- solder the provided header or an equivalent 2x3 header to the first 6 pins of the side double header
- make sure the coin battery is inserted into the coin cell slot
- connect as shown to your Pi
- Note: only the first (right most) 6 pins of the double header are actually needed, all other pins are not connected/used in any way
Configuration and usage:
- See this guide for configuring and using it on your Pi (DS1307 section)
-
For usage with ArduinoUNO or Moteino, connect as shown above, you will need 5V to the 5V pin, and connect the first 2 pins of the double header together
Then you can use one of the many Arduino libraries that support DS1307, and their examples (ex. adafruit's RTCLib)
