BIGTREETECH SKR 3 Control Board Bigtreetech Motherboard 32Bit Board latest for 3d Printer Machine

• BIGTREETECH SKR 3 Control Board is a latest-generation 32-bit 3D printer motherboard built to improve speed, motion handling, and upgrade flexibility.
• Powered by STM32H723VGT6 (ARM Cortex-M7) for modern firmware and smoother performance on advanced builds.
• Supports popular firmware options: Marlin, Klipper, and RepRapFirmware (RRF) for different workflows and printer needs.
• Wide motor driver compatibility (including TMC2209, TMC5160, A4988, DRV8825) makes it easy to reuse or upgrade drivers.
• Multiple expansion headers for upgrades like probe/BLTouch, filament sensor, and CAN FD—useful for Indian makers, labs, and print farms planning future mods.
• Note for buyers: this SKR 3 motherboard does not include an SD card.
