Turing Pi allows users to set up a Kubernetes cluster using Raspberry Pi compute modules. By housing up to seven compute modules, it becomes a compact solution that integrates networking, power, and storage elements.

2. Turing Pi 2:

The successor to Turing Pi, it allows mounting of up to four modules like Turing RK1, Raspberry Pi, and Nvidia Jetson. The board offers integrated power management, onboard 1 Gbps Ethernet, and a built-in Baseboard Management Controller (BMC) for improved automation and management.

3. ClusterHAT:

ClusterHAT interfaces a controller (Raspberry Pi) with up to four Raspberry Pi Zeros. It operates without external wiring, utilizing pogo pins to establish connections.

4. PicoCluster:

Designed to hold multiple Raspberry Pis, PicoCluster offers a cube-like design and aids in building scalable clusters, suitable for teaching, testing, or development.

5. BitScope Blade Rack:

BitScope Blade Rack supports up to 40 Raspberry Pi boards. With a standardized rack design, it focuses on scalability for large projects.

6. MiniNodes 5 Node Raspberry Pi 3 CoM Board:

The MiniNodes board is created to harness the Raspberry Pi 3 Compute Module, offering five nodes in a single board with integrated networking capabilities.

7. StackRack:

StackRack provides a vertical stacking solution for multiple Raspberry Pis. Its design offers easy access to each individual Pi.

8. ClusterCTRL Stack:

ClusterCTRL Stack manages up to five Raspberry Pi boards. It boasts a single power input and offers network booting capability.

9. RaspiBlade:

RaspiBlade is a 19-inch rack that can house multiple Raspberry Pis. It’s designed for those who favor a professional server rack setup.

10. PiBorg - TriBorg:

TriBorg by PiBorg is a GPIO expansion board, aiding users who want to expand their Raspberry Pi cluster capabilities.

11. MyPi Industrial Raspberry Pi Cluster:

Targeting professional applications, MyPi offers a robust cluster solution that can house up to four Raspberry Pi boards. It comes equipped with industrial connectors.

12. OpenIO Raspberry Pi Cluster:

Initially a demonstration project, OpenIO showcased the potential of ARM platforms for server ecosystems with its 384 Raspberry Pi nodes.

In summary, the Raspberry Pi clustering realm offers a diverse range of solutions, from simple setups for hobbyists to more complex and robust configurations for industrial applications.
