- Buffered Opto-isolated I/O
- Isolated PWM analog output signal for spindle speed control
- Charge Pump relay

- Buffered Opto-isolated I/O
- Isolated PWM analog output signal for spindle speed control
- Charge Pump relay (2 of NO, 1 of NC, 24V, 1A)
- ESTOP hardware logic to disable servo drives and Charge Pump
- All Inputs anti-noise low pass filter
- Hardware generate secondary X' step/direction from X step/direction for driving Gantry,
X' direction may different from X direction by JMP1
- Up to 3 more Open-Drain outputs could be extended for Flood/Mist/ATC etc
- On board FUSE and Smooth Capacitors for Drive voltage
