Turing Pi 2.5: A Mini-ITX Cluster Board for Raspberry Pi CM4 and Nvidia Jetson with AI Accelerators

The Turing Pi 2.5 is a modular, energy-efficient mini-ITX cluster board designed for building compact, noiseless server clusters. It supports up to 128GB of RAM and allows users to mix and match system-on-modules like Turing RK1, Raspberry Pi CM4, and Nvidia Jetson for general computing and AI tasks. A built-in Ethernet switch features a 1 GbE L2 switch with VLAN support, multiple SATA and M.2 ports, USB 3.0, PCIe slots, HDMI, and a GPIO compatible with Raspberry Pi.

The Turing Pi 2.5 is ideal for home labs, self-hosting, cloud-native applications (such as Kubernetes), and machine-learning projects. Users can extend its capabilities with third-party hardware modules like Wi-Fi, Bluetooth, 4G/5G, and various sensors, making it highly adaptable for data center-style setups in a smaller, quieter form.  It’s a great choice for developers and hobbyists needing flexible and scalable computing power because it is identical to Turning Pi 2.

Previously, we have written about similar cluster boards like the Turning Pi’s 7-slot Raspberry Pi CM3, the Deskpi SUPER6C Raspberry Pi CM4 Mini-ITX Board 6, the Risc-V Cluster from Milk-V supports Jupiter NX and Megrez NX module, and much more. Feel free to check those out if you are interested in the topic.
