If you want to build a good Real Time Clock for your Raspberry here’s the tutorial you were looking for!
This is a revised and simplified version for Instructables made out of this article at my personal blog. Difference is mainly in the structure and my article is a bit more verbose.
Why another “annoying” how to on building a Real Time Clock for the RPi?
Because almost everywhere you find instructions telling you to build the circuit on a breadboard and simply wire it with a couple of loose wires.
This is a full Stacking Shield you can elegantly install on top the RPi leaving the GPIO entirely exposed for other devices. And you can build it for no more than 8$, instead of buying one for double the price.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
