BIGTREETECH SKR V3 EZ 32-Bit Motherboard

Advanced Processing for Smooth Operation

At its heart is a 32-bit ARM Cortex-M7 STM32H743VI microcontroller running at 480 MHz, delivering significantly improved responsiveness and the ability to manage complex UI and motion controls effortlessly—resulting in fluid, stutter-free prints.

Versatile Driver and Voltage Support

This board is engineered for flexibility—thanks to its jumper-configurable motor voltage, users can raise it from 24 V to 48 V to unlock faster print speeds, though 48 V is only available when paired with TMC5160 Pro drivers. Compatibility extends across both proprietary EZ-series drivers and standard TMC models, ensuring broad hardware usability.

Firmware Compatibility and Connectivity

Plug-and-play compatibility with major open-source firmwares—Marlin, Klipper, and RepRap—gives users maximum control and customizability from day one. The board also integrates a micro SD slot for firmware updates, and supports common DIY interfaces such as WiFi modules (ESP32, ESP 07/S, ESP 12S), BLTouch, filament run-out detection, auto shutdown, RGB lighting, and more.

Safety and Thermal Performance

Built with reliability in mind, the SKR V3 EZ includes improved thermistor protection to safeguard against short circuits and thermal runaway. High-performance MOSFETs reduce heat generation, and a replaceable fuse ensures easy maintenance and added peace of mind.

Extensive I/O and Expansion Capabilities

The board offers multiple expansion options: dual CAN/USB ports (user-selectable), a non-elastic SDIO micro SD card slot (for faster data throughput), EEPROM for parameter storage, and numerous interfaces for sensors, fans, and peripherals.
