BIGTREETECH Scylla V1.0 CNC Control Board

Developed by BIGTREETECH in collaboration with Millennium Machines, Scylla delivers unprecedented precision and reliability for the most demanding CNC enthusiasts. Designed to excel in speed, stability, and accuracy, Scylla empowers you to revolutionize your projects.

Key Features:

• ARM Cortex-M7 STM32H723VGT6 MCU @ 550Mhz
• Supports RRF 3.5+ (with enough free memory for MillenniumOS!
• Passive cooling with integrated heatsink
• Separate, high-current voltage inputs for Motors and Auxiliary (MOS) circuits
• V-MOTOR – DC 24-60v, 10A max
• V-MCU – DC 24-60v, 3A max
• V-MOS – DC 24-60v, 10A max
• All high-voltage circuits fully opto-isolated and fused
• 4 x Integrated Trinamic TMC 2160 Motor Drivers (X,Y, Z, A axes)
• 4.7A RMS / 6.7A Peak
• Passive cooling with integrated heatsink
• +5V DC  ENA, STEP and DIR headers for external driver control
• Flexible Endstops / Inputs
• Endstops powered at 5v, 12v or V-MOS
• Probe and Toolsetter ports are individually selectable between 5v, 12v or V-MOS, with jumpers to select NPN or PNP
• Fully integrated Digital and Analog Spindle Control
• Enable and Direction  MOSFET-Switched outputs:
• Powered (5v, 12v or V-MOS, max 4.5A) or
• Unpowered.
• Digital (PWM) or Analog (0-5v, 0-10v) Speed signals
• Digital or Analog selectable by jumper
• Unpowered, requires voltage source – usually a reference port on VFD.
• Combine or separate grounds between Enable / Direction and Speed signals for improved compatibility with different VFDs and more straightforward wiring.
• Integrated RS485 Transceiver
• Control your VFD using Modbus over RS485, with feedback! (Pending software integration with RRF)
• RS485 source can be switched between MCU and SBC
• Integrated CAN Transceiver
• 120Ω termination resistor with jumper-select
• Extensive Auxiliary port configurations for cooling, solenoids and fans
• 1 x 250v / 10A max Relay, NO
• 3 x MOSFET-switched auxiliary circuits at V-MOS – 3A max
• 1 x Coolant, 1 x Mist MOSFET-switched circuits at V-MOS – 1A max
• 2.4GHz WiFi connectivity by ESP32-WROOM-32E-N4
• RGB Connector at 5V
• MillenniumOS supported
