BTT BigTreeTech Pi 2 Computing Core Board

3D printer users running Klipper firmware often face performance bottlenecks and connectivity issues with standard Raspberry Pi boards, which can limit remote control and advanced features. Without a robust computing core, print management and real-time monitoring can suffer, leading to inefficient workflows.

The BTT BigTreeTech Pi 2 Computing Core Board is a customized single-board computer designed specifically for 3D printer ecosystems like Klipper on Debian. Featuring a Rockchip RK3566 processor, 2GB RAM, and 32GB eMMC storage, it supports expansion via SD card and SSD, enabling smooth handling of print jobs, file storage, and surveillance video. Compatible with 12V/24V powered printers without needing an adapter, it integrates seamlessly with popular builds such as Voron 2.4, Trident, and other CoreXY systems. Connectivity options include dual-band 5G WiFi, Gigabit Ethernet, and support for DSI/CSI camera extensions, making it ideal for remote printing and monitoring.

Why Upgrade?

• Improves computing performance for Klipper firmware on CoreXY and Voron 2.4 printers, reducing lag and enhancing responsiveness.
• Enables direct 12V/24V power connection, simplifying wiring and reducing adapter failures common in DIY builds.
• Supports high-speed dual-band WiFi and Gigabit Ethernet for reliable remote printing and file transfers.
• Offers flexible storage options including eMMC, SD card, and SSD for managing large print files and logs.
• Compatible with camera extensions for real-time print monitoring and advanced UI setups.

Best For:

• Voron 2.4 and Trident builders seeking a powerful, integrated computing core for Klipper.
• CoreXY printer users requiring stable network connectivity and expanded storage options.
• DIY 3D printer enthusiasts upgrading from Raspberry Pi 4 for enhanced performance and connectivity.
• Users implementing remote print management and camera monitoring on Debian-based systems.
• Klipper ecosystem users needing a reliable, 12V/24V powered single board computer.

Pair With the Right Filament

Optimizing your 3D printer’s computing core with the BTT Pi 2 ensures smooth print management, especially when working with complex filaments that require precise control.

• PLA Filament — ideal for everyday printing with stable performance.
• PETG Filament — benefits from reliable print monitoring and control.
• TPU Flexible Filament — requires precise extrusion control enabled by robust computing.
