# Voron Leviathan
Voron Leviathan is collaboration between JNP and the team at LDO to create a controller board specific for the needs of Voron 3D printers. It features: 
- STM32H743 Microcontroller at 480Mhz 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
