This control board is a 32-bit MCU control board, which runs faster, the maximum no-load speed reaches 40000mm/min, the algorithm is optimized better, the vibration of the machine is smaller when the machine moves at high speed, and the performance is more stable; Using the Type-C USB interface, it is more convenient to and the data transmission is more stable; Support external drive, the reserved interface for external drive is with the high- drives on the market, which is convenient for wiring; The control board supply and line number circuit are isolated by optocoupler, the whole control board is and more stable; Y-axis dual drive, stronger drive capability;Support USB automatic identification. When plugged in USB and connected to the computer, it will automatically shield the offline interface to avoid offline interference with data. At the time, it supports external buttons, which can switch offline/USB control with one key; There are long strip-shaped mounting holes on the shell, which is convenient for the installation of various devices;Reserve 24V, 12V, 5V output ports to facilitate the expansion of various functions; Support USB flash firmware, firmware upgrade is more convenient Product Parameters: Product Name:4 Axis 3.0 Product Specifications:4 Axis Product Size:122mm x 87mm Product Weight:150g Operating System:Window/Linux/ Interface Type:TypeC Supply Voltage:DC24V- 5A Style:B Colour:As shown Material:Metal Package Contents: 1 * 4 Axis 3.0 Control Board Only the above package content, other products are not included.
