About this item

The BIGTREETECH BTT SKR 3 EZ is a high-performance, next-generation 32-bit control board designed for modern 3D printers. Built around the powerful STM32H743VIT6 ARM Cortex-M7 processor, running at 480 MHz, it delivers exceptional processing speed and reliability for advanced motion control and high-speed printing—especially with firmware like Klipper, Marlin, or RepRapFirmware. What sets the SKR 3 EZ apart is its support for EZ Driver sockets, enabling tool-free installation of BIGTREETECH EZ series stepper drivers. These slots also support standard drivers like TMC2209, TMC5160, and others in UART or SPI mode. With support for up to 6 drivers, it’s ideal for multi-axis and multi-extruder setups. The board features rich connectivity, including CAN Bus, USB-C, Wi-Fi support, and dedicated ports for BLTouch, filament sensors, auto fans, and RGB lighting. It also includes robust thermal protection, dedicated power management for hotends, bed, and fans, and support for 24V systems. Perfect for demanding 3D printer builds like Voron, CoreXY, or custom high-speed machines, the SKR 3 EZ offers cutting-edge performance, silent operation, and future-proof expandability in a user-friendly layout.
