1. The firmware is the prevalent Marlin, which is known for its stability, usability, and high-performance. 2. Adopt ATmega2560 as the main control chip, coupled with the high-performance USB serial converter FT232RQ. 3. The power pack: operating voltage is 12V-24V; double power supply design feeds for heatbed and logical part separately. The current is 12A for heatbed and 5A for other parts. The cooling fan can support 12V. 4. The main circuit adopts SMD fuse tube, the diode added to the power port can provide reverse protection to the whole circuit, in addition, the 5V USB is USB port protected with 500mA Recoverable fuse. 5??? 3 12v fan output and one PWM output for LED or other lighting equipment. 6. 3 55Amp MOSFET (with LED indicator, the actual output is restricted by the PCB board and the connector), all 3 MOSFET are equipped with heat sink to ensure sufficient heat dissipation and stable operation.Specification: Power Supply Voltage 12V Dimensions Size 11*8 cm Weight 90 g Package Weight One Package Weight 0.16kgs / 0.35lb One Package Size 19cm * 15cm * 5cm / 7.48inch * 5.91inch * 1.97inch Qty per Carton 120 Carton Weight 20.00kgs / 44.09lb Carton Size 60cm * 58cm * 50cm / 23.62inch * 22.83inch * 19.69inch Loading Container 20GP: 153 cartons * 120 pcs = 18360 pcs40HQ: 355 cartons * 120 pcs = 42600 pcs
