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

Classy, Comfortable, and Built to Last!
I’ve never tried a wooden wrist rest before, but after going through a few padded ones (even some expensive name-brand versions) that eventually peeled or fell apart, I figured this was worth a shot. And I’m so glad I did! This walnut wrist rest is smooth, beautifully made, and looks amazing on my desk. I have a whitewashed office setup, but this piece looks so good that I half-joked about wanting to change my desk to match it! It adds a very clean, grown-up aesthetic to the space. One thing I really appreciated is that it comes in several sizes to suit different setups. I ordered the largest available, and while it’s just a couple inches shy of covering the full length of my keyboard, it still works perfectly. It has non-slip grips on the bottom that keep it in place, and even though it’s made of solid wood, it’s surprisingly comfortable and ergonomic to type with. It’s also super low-maintenance—just wipe it clean with a damp cloth. For the $26–$29 price range, I think it’s a fantastic value and honestly better than some of the big-name options I’ve tried. This is a quality piece I expect to hold up for a long time, and I’m really happy with it!!

Check the height of your keyboard before ordering
This is a beautifully made, elegant looking wrist rest. The finish is satin perfectly smooth to the touch. As keyboards vary in height, be sure to measure he height of the front edge of yours before ordering—I didn’t (which is entirely my fault) and found that this wrist rest is just a wee bit too tall, which positioned my wrists a tad higher than I’m used to. Another factor you may want to consider are the ergonomics of solid wood versus other materials and your personal preferences (e.g., I tend to prefer cloth covered gel, because he cloth keeps my wrists from sticking and the gel is cushioning). My closing thought: this wrist rest is that it is by far the best looking of any wrist rest I’ve ever seen.

Amazing item!
Color: Brown
Amazing quality feels very nice to the touch, decent size, on the bigger side if you’re looking for a smaller table organizer, but still great!
