1、The control board supports A4988/8825/TMC2208/TMC2100 Dri. 2、The 2560 and ramps1.4 are assembled on one board, which solves the problem that the Ramps1.4 combination interface is cumbersome and easy to malfunction. 3、The user can replace the motor drive, support 4988 drive and 8825 drive, TMC2100 drive. 4、Reserve an external drive signal, which can be connected to a large drive to drive the 57 and 86 motors. 5、The use of high-quality MOSFET tube, better heat dissipation, to ensure long-term stability. 6、Using a dedicated power chip, support 12V-24V power input, to solve the problem of heat and power supply of Ramps voltage conversion chip. 7、The stable and reliable filter circuit greatly reduces the possibility of interference, and the most likely to avoid the phenomenon of crashes and runaways during the printing process. 8、Using CH340 serial chip, under the premise of ensuring stability and reliability, reduce costs, but also solve the problem of the previous 16U2 hard-to-install drive. 9、Using the open source firmware , the configuration and ramps1.4 are exactly the same, can directly replace Ramps1.4. 10、Can accept 24V input, the same system power can reduce the hot bed current to 1/4, effectively solve the hot bed MOS tube heating problem. 11、Can directly connect 2004LCD display and 12864LCD display, can support TFT28, TFT32 touch screen. 12、XYZ axle respectively use different color terminals to correspond to the motor and limit switch, convenient wiring. 13、User-friendly design, use different color terminals to distinguish the driving direction, reduce the probability of insertion and reverse, to prevent damage to the motherboard due to drive insertion.
