The CNC xPRO V4 is the culmination of over 5 years of CNC xPRO development. This controller brings a perfect union of easy setup and use with performance and reliability. The V4 board features isolated digital and analog power buses to greatly reduced noise and false triggers.

What's new for V4:

Less than 5-minute install with the use of plug and play motors headers, limit switches and power supplies
4-layer design featuring completely isolated motor and logic power buses
All smd parts moved to back of board to protect again debris and short
Integrated #4-40 standoff for easy mounting and short protection
Three ways to power - Laptop PSU (2.5x5.5mm plug), a 2 wire power supply, or ATX computer power supply
Selectable spindle output voltage range: 0-5V or 0-10V for full compatibility with spindles, VFDs, Lasers and more
Coolant output is now an open drain (directly sink up to 3A or use to control external relays)
Screw terminal hookup for external Step/Dir drivers makes beefing up easy
Extremely robust power management for overvoltage/reverse voltage protection including replaceable mini blade fuses
Motor driver step and fault LEDs for easier troubleshooting
Enhanced silkscreen with more pictures and less labels
Compatible with Openbuilds XTension wiring system for even easier setup!
DIP SWITCHES = NO MORE SOLDER JUMPERS - want to change decay mode -> slide the switch, want to clone Z motion instead of Y -> slide the switch
