Natasha,

Are you thinking what I am.

I have the same idea. Use this Board in conjunction with an Arduino (say) and make an MPPT controller.


That is exactly right! I want to use the ESP32 as the loop modifier.

Want to work on this together?

I paid $23 for mine just to get a version with all ICs marked and I now have them. TL494, LM358 and a small onboard 5V buck to power itself.

Feel free to purchase the cheaper ones that do not have ICs marked.

My current problem is that the board is smaller than I expected it to be and with my vision I need a good magnifying glass to trace it.

Are you also interested in tracing it? I have some pictures and @ltopower sent me much more detailed pictures as well
