I bought a VFO kit by PA0KLT based on the SI570 from SDR-kits. It was very easy to assemble although I dislike winding the transformer. Here is an image of it completely soldered. I also bought an extra Si570 to use in future projects of my own.
Connecting the display and buttons resulted in this mess, but it seems to work fine. It is possible to generate frequencies from somewhere around a few MHz to 280 MHz but since my oscilloscope only handles signals up to 100MHz I settled for 50MHz for the images here.
And finally, the signal on my oscilloscope.
Dear om,
I am searching for SI570 CODE UNO ARDUINO on
Do you have something simple to experiment?
I have a RX 6.1 Softrock I would put a frequency of replacement of quartz. eg 28.4000 mhz to 40 meters.
If you’ve ever worked on, can you give me a simple code parenir.
Thank you in advance.

I’m sorry, but I do not have anything like that. I have planned to write code for the Arduino to control the Si570, but since I don’t have my hardware completed I have not yet got there.
