## 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.

### SOM

- The LM3H SOM connects directly to the baseboard via 7 × dual M.2 M-Key vertical slots.

- The M4N SOM connects to a dedicated adapter board through a BTB connector, which then interfaces with the baseboard.

### Adapter Boards

- The CM4 / CM5 adapter board features a BTB connector on the front side, supporting CM4 and CM5 SOMs. It also includes a Boot button and a Type-C port for flashing. The back side includes an SD card slot, an M.2 NVMe SSD connector (compatible with 2242 or 2230 size), and a reserved USB pad for optional CM5 USB 3.0 support.

- The M4N adapter board features a BTB connector for Sipeed M4N SOMs, a Boot button, and a Type-C flashing port on the front side. The back side includes an M.2 NVMe SSD connector (2242 or 2230), and a reserved USB pad for optional USB 3.0 support.
