Hi dave m.

The fundamental difference is the main microcontroller from another family.
GT motherboards are equipped with AVR 8-bit - ATmega 2560.

GTM motherboards, specifically GTM32 Pro vB, feature Cortex M3 32-bit STM32F103VET6.

These are logical systems of a completely different class.

Unfortunately, I don't have any images of the GT2560 that I could boast of. But I think you have it ;-)
