• Based on MEGA 2560, a single-board solution, higher stability
• Supports dual extrusion
• Supports heated bed (maximum current not to exceed 9A, temperature-controlled below 100 C )
• Power: 19-24V DC (you can use a laptop power supply or switching power supplies)
• Three temperature sensors (PT100, -200-650 ), Texas Instruments INA826 dedicated chip, high precision anti-interference ability
• Three limit switches, the default reset to position 0, the default bed size: 230 x 225 x 205
• High scalability, reserved way ANALOG IN, other unused I / O port pin were also set aside, for user expansion
• Two Safety switches (which can be accessed smoke sensors, to prevent the occurrence of accidents)
• Three fan Interfaces: Adjustable fan connectors (J14, FAN PWM, 24V), 5V fan (J34, FAN 5V), 24V fan (J20, FAN 19-24V)
