what board is this

Hi All,

Does anyone know what board is this (attached photo). I want to update the firmware and not sure what board I have to select in Arduino. The processor on it is ATmega64A.

The intent is to use it with Marlin and Pronterface. Current info I have got is it works on replicator 37. the manufacturer didnt mention what firmware they have use (This is from China, so not much information or support is available)

Thanks in advance.

It looks like it is a Gen 6 clone of some sort, considering they used the atmega644.

Do you know if there is a marlin firmware for this.

its says atmega64A not 644.

Have you tried a M115: Get Firmware Version and Capabilities ?

See if tells you anything.

If you cant find the board specs uploading new firmware is never going to work... you will need to trace every IO pin and work out what pin is connected to what device.
