Phase lock loop controller

I am looking to develop a phase lock loop controller with auto tuning capabilities for a little project that I am doing.

I was thinking that the Freedom 300 would be more that well suited for such a project.

I have a few of the chips but haven’t gotten around to doing anything useful with them just yet.

There is the [HiFive1] ( but that seems like a bit of an overkill for my project.

Are there any smaller Freeom 300 boards with a little memory, some serial connection and some gpio pins to handle the IO?

Michael Welling used FE310 chips to create the open source “LoFive” board, which you can assemble yourself, and has also had a manufacturing run on groupgets.

Thank you, I ordered 2 boards.
