BIGTREETECH SKR MINI E3 V3.0 32 Bit Control Board for Ender 3/Ender 3 Pro/Ender 5/Ender 5 plus/CR-10

BIGTREETECH BTT SKR Mini E3 V3.0 32-Bit Control Board – Silent Drop-in Upgrade for Ender 3

The BTT SKR Mini E3 V3.0 is a powerful 32-bit control board designed as a direct drop-in replacement for the stock motherboard on Creality Ender 3, Ender 3 Pro, Ender 5, Ender 5 Plus, and CR-10 series printers. Powered by the STM32G0 ARM Cortex-M0+ MCU, it delivers faster processing, more stable performance, and significantly quieter operation compared to the original 8-bit board.

Equipped with four onboard TMC2209 UART silent stepper drivers in StealthChop2 mode, the SKR Mini E3 V3.0 provides ultra-quiet printing with reduced vibration. It supports both Marlin and Klipper firmware, making it an ideal upgrade for users seeking smoother motion, sensorless homing, and advanced features.

Key Features:

• STM32G0B1RET6 / STM32G0B0RET6 32-bit MCU for reliable high-speed performance
• Integrated TMC2209 UART drivers (4 channels) for silent and efficient stepper control
• Dual Z-axis motor interfaces with parallel design for stable dual-Z setups
• Sensorless homing support (StallGuard) – no need for physical endstops on X/Y
• Improved large heatsink for better thermal performance (20% improvement over previous versions)
• Three CNC fan interfaces + dedicated 5V output for BLTouch, RGB, and TFT screens
• Multiple expansion options: Z-probe, filament sensor, power-loss detection, PS-ON
• Micro USB port for easy firmware updates and PC connection
• Compatible with original Ender 3 LCD12864, 2.4"/3.5" TFT touchscreens
• Board size: 103.75 × 70.25mm with perfect mounting hole alignment
