Hello, I am Bart Dring. I am the designer of this controller and one of the original creators of FluidNC firmware. The profits from this controller directly help support the firmware development. Thank you for considering this product.
This is a CNC I/O module design to be used with 6 Pack CNC Controllers . This can be used with spindle controllers that require a 0-10V analog voltage for speed control. It also has (2) opto isolated digital outputs that can be used for signals like direction. It has a potentiometer to adjust the output voltage, so it can be used with 3.3V and 5V signals. With a 3.3V signal the full speed output can be adjusted with the potentiometer from 4.75V to 11V. It has (3) LEDs to indicate the status of the outputs. The brightness of the LED on the spindle output pin will be proportional to the 0-10V output. It has a pluggable terminal block that can be installed horizontally or vertically.
