Installing Marlin on Weedo F100 Mini 3D Printer.

Hi,

I have a Weedo F100 Mini 3D Printer, which was also sold as a Festnight F100 Mini or Funtastique EVO 3D Printer, and I would like to install Marlin firmware on the controller. I looked up the supported boards list on marlinfw.org and the board was not listed. But maybe the controller board is a knock off of a supported board. I disassembled the controller and took pictures of the board. Does anyone recognize this board or has already installed Marlin on it? Also the board has a 512MB SD-Card on it, which is not user accessible, with a bin file on it. Maybe Marlin can be installed and or run from there?

That is unknown.

I see a CH376 usb chip, which marlin doesn't know how to talk to.
And a MAX6675, so is using thermocouples, not thermistors

Main cpu is under heatsink so cannot tell what it is, other than it is very small and has 64 pins,
The 8 mhz crystal makes me think its a stm32f1xx not an arduino...
