In order to meet the customer for expanding Gemini, we made a 4-axis expansion board. The original Gemini 4-axis board can be expanded to 8-axis to meet the needs of more 3D printers. This expansion board would have limited functionality in a stand alone configuration as a 3D printer motherboard because it does not include heating and temperature measurement functions.
