Featuring a 40-pin GPIO, Gigabit Ethernet, 4 USB 2.0 ports, dual micro HDMI, and USB-C power input, it enables seamless Klipper firmware operation for advanced 3D printer control and diverse applications in AI, robotics, and smart home systems. ## 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. Review: Work well - worked will without any issues. Review: Great pi alternative - I have 2 of these now since it is almost impossible to find an actual pi. I had real trouble with the first one I bought in getting it to work correctly. BTT support was slow to answer but they did finally make it right buy replacing the CB1, After that it has worked great so I bought another and it worked the perfectly the first time I tried it. I believe that they have worked out the bugs and now they are a good product. I will probably be buying another. ## 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.

I had real trouble with the first one I bought in getting it to work correctly. BTT support was slow to answer but they did finally make it right buy replacing the CB1, After that it has worked great so I bought another and it worked the perfectly the first time I tried it. I believe that they have worked out the bugs and now they are a good product. I will probably be buying another. ### ⭐⭐⭐⭐ Almost identical to a Raspberry Pi 4 model B footprint *by J***G on October 2, 2022* This board is great in that it is almost identical to a Pi 4 model B in its layout—the ports are all in the exact same places, though the DSI and CSI display/camera connectors are slightly different due to the Compute Module's positioning. Also missing is any USB 3.0 (that is replaced by two extra USB 2.0 ports), and there is no PoE HAT compatibility. The Ethernet port is labeled as 1Gbps, but will only be 10/100 if you buy BigTreeTech's CB1 board instead of a CM4. There are a few dipswitches for setting write protect, flashing eMMC, etc., but they are very tiny and hard to reach, you need a tiny tool to get in there if you want to use this board to flash a device. There's also a 5V/GND header to plug in a non-PWM fan at the edge of the board. Overall it's put together well and works great with both a CB1 and CM4 that I've tested. ## Frequently Bought Together - BIGTREETECH Pi4B Adapter V1.0 for Raspberry-Pi CM4, BTT CB1 V2.2/CB1 eMMC/CB2 Core Board Compatible SKR Mini E3 V3.0/SKR V1.4 Turbo/Octopus V1.1/Pro to Running Klipper for Voron/CoreXY/i3 3D Printer - BIGTREETECH SKR Mini E3 V2.0 New Upgrade Control Board 32-Bit with TMC2209 UART Driver 3D Printer Parts Cheetah for Creality Ender 3 - BIGTREETECH CB1 Heatsink for CB1 V2.2 Core Board CB1 eMMC V1.1 Control Board Compute Core Board 3D Printer Parts --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.dk/products/470399404-bigtreetech-pi4b-adapter-v1-0-for-raspberry-pi-cm4-btt](https://www.desertcart.dk/products/470399404-bigtreetech-pi4b-adapter-v1-0-for-raspberry-pi-cm4-btt) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-04-23*
