Offline Controller 32-Bit 4 Control Board, GRBL Control, B

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 use and the data transmission is more stable; Support external drive, the reserved interface for external drive is consistent with the high-power drives on the market, which is convenient for wiring; The control board power supply and line number circuit are isolated by optocoupler, the whole control board is and more stable; Y- dual drive, stronger drive capability;Support USB automatic identification. When plugged in USB and connected to the computer, it automatically shield the offline interface to avoid offline interference with data. At the same time, it supports external buttons, which can switch offline/USB control with one key; There are long strip-shaped mount
