The schematics of these clone are floating around and easy to find. Picture #7.

Yes, but that wasn't my point. My point was that clone vendors don't usually provide their own (COPIED) schematic unless purchasing from them. As if they had their own original I.P. to protect.

Most electronic kit sellers on e-bay are resellers who know absolutely nothing about electronics. Buyer beware. You need to know what you want to buy DIY electronics on e-bay. I have had some gem and also some which go directly to the trash can.
