Si5351 Clock Module

I ordered a couple of the Adafruit Si5351 Clock Modules that arrived this week, and quickly soldered up the header and plugged it into a breadboard.




I first tried the Adafruit library and verified its ability to generate multiple output clocks, however it is a bit crude compared the NT7S Library. To use his Library I did find I needed to use the latest Arduino IDE for his example sketch to compile. After that it was very easy to generate any frequency in the HF range.

This module will be useful in many projects. People are using them in place of the standard DDS modules. In fact M0XPD as released an awesome dual VFO sketch with LCD display and rotary encoder.
