Leviathan Controller Board MCU by JNP, Voron Design and LDO Motors for Klipper Printers

Voron and Klipper enthusiasts understand that generic controller boards often lack the precise features and reliability needed for high-performance CoreXY printers, leading to firmware limitations and hardware incompatibilities that can disrupt print quality and stability.

The Leviathan Controller Board MCU, developed collaboratively by JNP, Voron Design, and LDO Motors, is engineered specifically for Voron 2.4, Trident, and similar Klipper-based CoreXY printers. Featuring an STM32F446 MCU, dual 24-48V power inputs with polarity and overvoltage protection, and multiple thermistor and fan outputs, this board delivers robust control tailored to the demands of advanced 3D printing. Its integrated CAN Bus, USB-C interface, and Raspberry Pi mounting options streamline connectivity and integration within the Klipper ecosystem, making it a preferred 3D printer mainboard for Voron community builders and high-end CoreXY setups.

Why Upgrade?

• Voron 2.4 and Trident builders gain a board optimized for Klipper firmware with native support for advanced features like CAN Bus and multiple thermistor inputs.
• Improved power management with dual protected 24-48V inputs reduces risk of damage and supports high-current stepper drivers like TMC5160.
• Enhanced connectivity options including USB-C and Raspberry Pi mounting simplify integration and maintenance in CoreXY builds.
• Better stepper driver cooling and dedicated expansion ports allow for future upgrades and stable high-speed printing.
• Designed in collaboration with LDO Motors, ensuring compatibility with premium Voron kits and community standards.

Best For:

• Voron 2.4 and Trident builders seeking a reliable, Klipper-optimized mainboard.
• Switchwire users requiring robust power input and advanced connectivity.
• CoreXY enthusiasts upgrading to a dedicated controller board tailored for high-performance printing.
• Klipper firmware users wanting seamless integration with Raspberry Pi and CAN Bus peripherals.
• DIY builders looking for a compact, feature-rich controller with expansion capabilities.
