Voron Leviathan

The Voron Leviathan V1.2 is collaboration between JNP and the team at LDO to create a controller board specific for the needs of Voron 3D printers. It features:

  • STM32F446 Microcontroller at 180Mhz clock speed.
  • Reverse polarity protection for main power supply and HV Stepper supply input
  • Superior stepper driver cooling (passive)
  • Dedicated mounting space for a Raspberry Pi 3,4,5 or Zero 2W
  • Dedicated power supply and uart port for Raspberry Pi
  • 5x Integrated TMC2209 stepper drivers.
  • 2x Integrated 48V rated TMC5160 stepper drivers.
  • 4x Fan ports with flyback protection, 5V/24V selectable voltage, and tachometer inputs.
  • 4x Thermistor ports with 2k2 ohm pullup resistors.
  • 1x Dedicated LED strip with flicker free dimming down to 1%.
  • 1x Neopixel port.
  • 1x Hotend power output up to 180W.
  • 1x Hotbed power output up to 240W
  • 1x Dedicated Z probe port with selectable voltage and integrated diode.
  • 3x Endstop ports and a filament sensor port
