Mach3 USB Motion Board

3/4-axis USB interface board for use with Mach3.

No USB driver installation is required; it can be used after plugging into the computer.
Supports USB hot-swapping and monitors USB connection status at any time.
Maximum step-pulse frequency is 200KHz, suitable for servo or stepping motor use.
Status indicator LED shows USB connection and working status by flashing.
16 general-purpose inputs with individual indicators, so input signal states are clearly shown.
With on-board isolated power supply; an external power supply is not required. This simplifies the power requirements of the electronic control system. External power can also be applied to reduce USB load.
Feed rate, spindle speed rate, or jog rate can be controlled by the adjustment knob.
10 high-speed optocouplers at 10MHz and 24 general optocouplers isolate all input/output signals. This design can provide high performance and a stable system.
Fully supports Mach3 software limit and backlash functions.
Real-time speed chart allows spindle speed changes to be observed.
Fully supports Mach3 versions, including Mach3 R3.043.066.
Supports Windows series.
