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
