Introduction
NanoCluster is an ultra-miniature cluster board developed by Sipeed, featuring 7 SOM slots interconnected via a RISC-V-based Gigabit switch. It supports USB-C PD power supply and optional PoE expansion. Additionally, NanoCluster provides independent UART and power control, making it an ideal entry-level platform for HomeLab users exploring distributed computing, Kubernetes, Docker, and edge computing.
NanoCluster is compatible with Sipeed's Longan Module 3H (4 × Cortex-A53), M4N (4 × Cortex-A55 + NPU), as well as the Raspberry Pi Compute Module 4 (4 × Cortex-A72) and Compute Module 5 (4× Cortex-A76). Users can freely choose compute modules based on performance needs and budget, or mix and match different architectures to build a highly customized and heterogeneous computing cluster.
The NanoCluster adopts an open SOM interface standard, supporting both official core modules and custom adapter boards for third-party SOM solutions. This design greatly enhances the platform's flexibility.
