I am afraid I don’t have the pcb designed as yet but I hope to do so shortly.
Corona related matters have hindered further work on my mppt project. Right now I am busy with a house related project which will take at least 3 to 4 weeks to complete.
I live in a village which makes it a bit difficult to source components or other electronics related stuff. Corona adds to our woes as we minimize travel to Pindi.
Nice to know that you are making an attempt in the same direction. I planned to use the Faisal PCB as a starting point. Instead of putting in the regular mcu you can make a piggy back arrangement and put in an 8266 using a Vero board like an Arduino shield. I can share pics and ideas if you wish to collaborate on the project. My whatsapp number is 03020050060. Please let me know what you think.
Secondly I got 3 PCBs from Faisal. I can certainly send you one. You can then clone it into as many as you like.
