LO Guv'nor: Si5351-based 3x clock generators for the workbench
This is a very simple way to transform the widely used Si5351 modules into a useful lab/workbench tool. The entire purpose is to get access to these three clock generators--which can provide clocks in the low kiloHertz up to hundreds of MegaHertz--with minimal interruption to your workflow.
A rotary encoder, an OLED display, and a few momentary switches are all glued together through this basic PCB and bundled with a Nano and the code that provides a quick, and hackable, user interface to the clock generator.
This can be used to prototype Si5351 chip/module use, of course, but is mainly meant to provide mid-range clock signals for driving prototypes and tests. Less capable that a true signal generator--it only outputs square waves--but it offers coverage of a wide band of frequency ranges that go beyond what typical (read: inexpensive) function generators can handle.
A full walk-through video, covering the simple hardware, and diving deep into the software created, is be available:
This version of the boards includes some fixes and additional features, which will be covered in future online documentation and video.
