  • Uses 32-bit main frequency 72MHz ARM level Cortex-M3 series STM32F103RCT6 main control chip
  • it is equipped with Marlin2.0, a highly modular open-source firmware, which is convenient for users to do DIY and secondary development, avoiding the worries that they cannot master the core code
  •  Use powerful development tools, Visual Studio Code integrated development environment: support online debugging, more helpful for product development and performance optimization, using C language development, low development threshold
  •  The PCB board wiring is rigorous and beautiful, and has been specially optimized for heat dissipation
  •  A dedicated power chip is used to support 12-24V power input
  •  24V input can be accepted. The current of the hotbed can be reduced to 1/4 under the same power, which effectively solves the problem of heat generation of the MOS tube of the hotbed
  •  Support 2.8 inches, 3.5-inch color touch screen and original LCD12864 screen of Ender3 printer
  •  Upgrade configuration firmware through SD card, easy to operate;) Use firmware to set the drive current to avoid burning the drive-by manually adjusting the current, which is convenient, safe, and reliable
  •  Support BLtouch, RGB color lights, locked rotation detection, shutdown after shutdown, etc.
  • The integrated UART mode of TMC2209 makes the debugging of the motherboard and driver simple and integrated
  •  The expansion ports of some pins of TMC2209 are reserved to facilitate users to use DIAG instead of Endstop
