Featuring a 40-pin GPIO, 4 USB 2.0 ports, dual micro HDMI, and Gigabit Ethernet, it offers expansive connectivity and supports Linux and Windows 10 IoT. Ideal for Klipper-based 3D printing setups, AI projects, and smart home applications, this cost-effective adapter is backed by open-source STL case files and strong community support. ## Description Say "Goodbye" to the old days that we have to purchase Raspberry-Pi to run Klipper.Now we're entering a new phase that BIGTREETECH launched Pi4B adapter, which can perfectly serve as Raspberry-Pi 4B with the combination of CM4/ BTT CB1 core board.Equipped with the standard Pi CM4 sockets, BIGTREETECH Pi4B adapter fits all versions of CM4 board, which is ideal and cost-effective replacement for Pi 4 Model B. When worked with BTT CB1 V2.1 core board, it basically could replace Pi 3 Model B as well.Main Features1.Standard Pi CM4 Sockets:Fits all versions of CM 4 board to replace Pi 4 model B.2.40-Pin GPI0:Offer you with wide range of connectivity to meet users' DIY needs.3. USB TYPE-C Power Supply Port:Make it easy to write system,and provide with stable power supply.4. Multiple Interfaces:Comes in onboard 1000M ethernet port, dual micro-HDMI ports, CSI camera port, 4x USB 2.0 ports, etc.5.Cost-effective to Run Klipper:The combination of Pi4B adapter and CM4/ CB1 costs you with less, and can be combined with BTT motherboards, which enables you to run Klipper6.Wide Application: The combo set of Pi4B and CM4 can be applied in various fields, such as, writing programmes, artificial intelligence, smart home, etc.It basically puts a CM4 into the footprint of a Pi4B adapter, along with the HDMI ports, USB-C power input, and 4x USB 2.0 ports, along with Gigabit Ethernet.It doesn't seem the PCIe bus is exposed in any way, but it has a CSI connector on top, and a flat DSI connector on bottom. Beaware that it only supports CSI and DSI when work with CM4 board; it only supports SPI/HDMI screen when work with BTT CB1 core board.The PI4B adapter is a cost-effective replacement for Klipper system.There are also STL files for a case on BIGTREETECH Github.Any problems regarding BIGTREETECH Pi4B adapter,please feel free to contact us. ## Features - Cost-effective option: Pairing PI4B Adapter with CB1, the function is close to the Raspberry-Pi 3B. With Bigtreetech motherboard, you can run the Linux system efficiently. The most value way using Klipper! When matching with the Raspberry-Pi CM4, the function is exactly the same as the Raspberry-Pi 4B. - Board to Board Connector: Use the same BTB connector as Raspberry-Pi, perfectly compatible with the various versions of the Raspberry-Pi CM4, and easily install the CB1/CB2. The 40-PIN GPIO interface is compatible with the Raspberry-Pi ecology to meet more DIY needs. - Abundant Expansion Interfaces: Our Pi4B adapter features with Gigabit Ethernet port, 5V fan port, 4*USB 2.0 ports, dual micro HDMI ports, CSI/DSI port, microSD slot, provide more features and convenience. - Wide Application: Use this Pi4B assemble a micro, low -cost computer, support ARM GNU/Linux distribution and Windows 10 LoT. Can be applied in the fields of computer vision, smart home, voice recognition, robot programming, artificial intelligence, etc. - Small tips: We provide the STL file for the Pi4B+CB1 shell at Bigtreetech GitHub. If needed, you can download and print.
