The NanoCluster is an ultra-mini cluster board with seven onboard slots, interconnected by a RISC-V-based Gigabit switch, supporting USB-C PD and expandable PoE. It also provides UART and power control, making it an ideal choice for HomeLab users started with distributed computing, Kubernetes and Docker practices, and edge computing. NanoCluster is compatible with for Technology's Longan Module 3H (4 x -A53) and M4N (4 x -A55 + NPU), as well as the for Compute Module 4 (4 x -A72) and Compute Module 5 (4 x -A76). Users can freely choose core modules based on performance requirements and budget, or mix and match core modules with different architectures to build a highly customized computing cluster. NanoCluster utilizes an open System-on-Module () interface standard, supporting not only official core modules but also user-designed adapter boards for custom core modules or other solutions, greatly enhancing the platform's flexibility.
