BIGTREETECH Pi2 V1.0 is a powerful Klipper board based on the Rockchip RK3566 processor, supporting versatile expansions. This next-generation board offers optimized processing and storage performance, enabling 3D users to process print jobs quickly and smoothly.

BIGTREETECH Pi 2 & CB2:

Developed by BIGTREETECH, the Pi 2 and CB2 are second-generation motherboards that offer significant improvements in computing and storage performance compared to their predecessors. Designed to meet the needs of 3D printer users, these new models have optimized their design to provide a more user-friendly and accessible experience.

Key Features:

These boards not only support various expansion functions but also can be connected to 12V/24V powered 3D printers without an adapter, making them very convenient for users.

Rockchip RK3566:

With an RK3566 processor and powerful storage function, the Pi 2 board features 2GB of built-in RAM and 32GB of eMMC ROM. It also supports SD cards and 2M solid-state drive expansion to meet all your basic needs for running Klipper on Debian, software storage, documents, and surveillance videos.

Support for DSI/CSI Extension:

The camera can be connected via the DSI interface and the FPC port on the BTT PITFT screen, or to the BTT HDMI screen via the HDMI interface.

Support for 5G Network:

Dual-band WiFi and Gigabit Ethernet ensure seamless connectivity for remote printing and file transfers.

Important Notes:

Pi 2 does not have an SPI interface: If you need to use an SPI screen, you need to connect it with IO2 CAN or EBB and U2C.

Size: The CB2 has the same size as CB1/CB1 eMMC and Raspberry Pi 4B/CM4, but the Pi 2 is slightly longer than Raspberry Pi 4B. Refer to the Pi 2 size chart to choose the appropriate installation location.

Heatsink: The CB1 heatsink cannot be installed on CB2, and CB2 can work without the heatsink.

Technical Specifications:

2GB LPDDR4 RAM: Offers significantly faster data transfer speeds, resulting in smoother operation, faster file loading, and overall improved responsiveness in 3D printing tasks.
Flexible 12-24V Input: Ensures compatibility with your 3D printer's power system.
32GB eMMC Storage: Stable, shock-resistant Klipper operation with 10x the endurance of TF cards, ensuring stable, high-speed performance.
CSI/DSI Interface: Supports cameras and displays.
0.8 TOPS NPU: Enabling the future of AI-powered 3D printing.
Gigabit Ethernet + 2.4/5G: Dual-band WiFi and Gigabit Ethernet ensure seamless connectivity for remote printing and file transfers. Simply connect the included WiFi antenna for a stronger and more stable WiFi signal, effortlessly enhancing your device's connectivity.
40-pin GPIO: Compatible with the Raspberry Pi ecosystem.
Rockchip RK3566: With a lightning-fast RK3566 processor running at up to 1.8GHz, the BIGTREETECH Pi/CB2 takes Klipper printing performance to unprecedented heights. Say goodbye to sluggish response times and hello to buttery-smooth operation.

The cooperation between Klipper and BIGTREETECH makes the firmware for 3D printing enthusiasts more convenient to use and helps to further improve the printing experience. BIGTREETECH is committed to establishing a complete 3D printing ecosystem, striving to bring more possibilities to the 3D printing industry and pushing the technological advancement of 3D printers to make them faster, better and easier to use.
