Yoetaun SKR 3 EZ V1.0 32bit 480MHz Mainboard 12-48V Black

SKU CH-0WYC-VFGGV

32-bit 480 MHz mainboard running 12-48 V with anti-misplug driver sockets, three fan headers and PT1000 support for Klipper or Marlin 3D printers

  • ColorBlack
  • Faster printing with motor voltage up to 48 V using EZ5160 Pro driver
  • Anti-misplug design prevents driver and mainboard damage from incorrect installation
  • 32-bit 480 MHz ARM Cortex-M7 STM32H743VI processor boosts speed and accuracy
  • Built-in PT1000 thermistor support removes need for external temperature module
  • Compatible with TFT35, TFT28, 12864 displays and EZ2209, EZ2208, EZ5160, TMC2209, TMC2208, TMC5150 drivers

32-bit 480 MHz mainboard for Klipper printers

The Yoetaun SKR 3 EZ V1.0 is a 32-bit control board built around a 480 MHz ARM Cortex-M7 STM32H743VI processor. It accepts 12 V to 48 V motor supply and supports Marlin, Klipper and RepRap firmware. Three fan headers and anti-misplug driver sockets protect hardware during assembly.

Makers upgrading Ender-3 style machines

Suits builders who want faster print speeds through 48 V operation with EZ5160 Pro drivers and who need native PT1000 thermistor support without extra modules. Not for users staying on 12 V or 24 V only, nor for printers that require more than three fan headers or different LCD interfaces.

48 V motor voltage capability with EZ5160 Pro driver

The board’s voltage range tops out at 48 V, but that level is only usable when EZ5160 Pro stepper drivers are installed. With standard EZ2209, EZ2208, TMC2209, TMC2208 or TMC5150 drivers the practical limit remains lower, so driver choice decides whether the high-speed benefit is available.

Questions about this item

Does the SKR 3 EZ V1.0 board come with stepper drivers or do I need to buy EZ2209, EZ5160 or TMC5160 units separately?

The board is sold without drivers; you must purchase compatible EZ2209, EZ2208, EZ5160, TMC2209, TMC2208 or TMC5150 modules separately.

Which driver should I choose for 48 V operation versus standard 12–24 V printing?

Use the EZ5160 Pro driver for 48 V input; for 12 V to 24 V any supported EZ or TMC driver will work.

What does the 480 MHz STM32H743VI processor mean for Klipper performance on this board?

The 32-bit 480 MHz Cortex-M7 core provides faster step generation and higher printing accuracy when running Klipper or Marlin firmware.
