Description

The LDO Leviathan V1.3 is a comprehensive control board built on STM32F446 architecture with native Klipper firmware support. It features dual power supplies (24V main, 24-48V for TMC5160 drivers), five TMC2209 and two TMC5160 stepper drivers for advanced motion control, four independent thermistor inputs, four PWM fan outputs with tachometer support, and dedicated heater outputs for hotend (180W) and heatbed (240W) applications. Additional capabilities include probe and filament sensor inputs, addressable RGB lighting control, three endstop inputs, and an expansion port offering ADC, UART, SPI/CAN connectivity with auxiliary power rails, ideal for complex multi-axis printer configurations and advanced sensor integration.

Note: Order after 28/07/2025 are shipping newer V1.3 version.
