CJMCU-5351 Si5351A I2C Clock Generator Breakout Board For Arduino Projects

Hey makers and hackers!

Need a clean, programmable clock signal for your next Arduino project?

This CJMCU-5351 breakout board is built around the Si5351A chip—an I2C-controlled clock generator that can output multiple frequencies simultaneously.

Great for synths, RF experiments, or any time you need precise timing without cluttering your breadboard with discrete parts.

It's unbranded but brand new, ready to solder or jumper into your setup.

If you're messing with signals, this little board opens up a world of possibilities.
