RATTMMOTOR 4 Axis GRBL CNC Engraver Machine Controller Board USB Port, Support 775 Motor or 300W/500W 48V Spindle Motor, External Drives/ Limit Switch/ Probe/Offline Controller Can be Connected
✅This control board is a 32-bit MCU control board, running faster, the highest no-load speed up to 40,000mm/min, better algorithm optimization, less vibration when the machine moves at high speed, more stable performance.
✅Use Type-C USB interface, more convenient to use, more stable transmission data; support USB brush firmware, firmware upgrade is more convenient.
✅Support USB automatic identification, when plugged into the USB connected to the computer, automatically shield the offline interface, to avoid offline interference with data, while supporting external buttons, you can switch offline/USB control with one key.
✅Y-axis dual drive, drive more powerful; reserved 24V, 12V, 5V power output port, convenient to expand a variety of functions; support for external drive, external drive reserved interface is consistent with the market high-power drive, convenient wiring.
✅ Control board power supply and line number circuit using opto-coupler isolation, the whole control board is safer and more stable; shell with long mounting holes, convenient for a variety of different devices.
