The LDO Leviathan 1.3 is a feature-rich control board designed for advanced CoreXY 3D printers, including Voron builds. Engineered for reliability and ease of integration, it combines powerful processing, multiple stepper drivers, and native support for CAN bus toolheads. With thoughtful layout and robust components, the Leviathan 1.3 offers smooth motion control and seamless expansion for demanding printer setups.

Features

  • Supports both Klipper and (via new MCU) RRF firmware
  • Uses an STM32H743ZIT6 microcontroller (upgraded from STM32F446) for improved performance
  • Dual-supply design: one Vin for 24 V main board and another for 24-48 V stepper driver supply (polarity and over-voltage protected)
  • On-board drivers: 5× TMC2209 (24 V) + 2× TMC5160 (24-48 V) with dedicated 12 V gate drive
  • Four thermistor inputs
  • Four fan outputs supporting tachometer feedback and selectable 5 V or 24 V via jumpers
  • Single probe input (with selectable 5 V or 24 V via jumper) and a filament-sensor input (5 V tolerant)
  • Neopixel output port for addressable LED strips
  • Endstop support: 3× endstop inputs (5 V tolerant)
  • Heater outputs: one hot-end channel (up to ~180 W / ~7.5 A) + one heatbed channel (up to ~240 W / ~10 A)
  • Dimmable LED-strip output (constant current, ~350 mA) built-in
  • Expansion ports: EXP1 & EXP2, plus an “Extension” port with multiple ADC, UART/SPI/CAN, GPIOs and 3.3 V/5 V/24 V supply taps
  • Interfaces: USB-C for programming/firmware, CAN bus via MicroFit connector
  • Direct Raspberry Pi mounting support: 5-pin JST-XH connector for Pi power (UART support) and mounting holes for RPi Zero 2W / RPi3/4
  • Stepper driver cooling improved (better passive cooling design)
  • Physical dimensions: 170 mm × 100 mm, with mounting-holes spacing of 160 mm × 90 mm

I think it’s working. Slows the grow back.
Size: 2.02 Fl Oz (Pack of 1)
I have noticed my hair grows back slower than normal. So I guess it’s working for the month I have been using it.

Facial oil for hair removal
Size: 2.02 Fl Oz (Pack of 1)
Very nice oil. I use on my face to help slow down the extra chin hairs that keep popping up/out. It has helped greatly to get my facial hair in check. Very little plucking after using this oil for a few months.

Did not work for my skin
I ordered this for a more natural at home remedy for my eczema but it did not work. Even after seeing a dermatologist and healing my eczema using this product did not help my skin sadly.
