Micro SD Card port.

The Majority of the Connectors are JST-XH 2.54mm. The TFT is Dupont connectors and most the rest are screw down block connectors.

Recommended software: CURA, Simplify3D, Pronterface, Repetier-host, Makerware.

Note: This is a DUAL Z, single extruder, single hotend, heated bed board. They added a onboard EEPROM rather than using a simulated EEPROM as in the Mini E3 V1.2. There is also "Automatic Shutdown" added to this board. Upgraded Bed MOSFET. Upgraded power chip to 2.5A. There is added jumpers for Sensorless homing setup. plus more!
