The NanoCluster is a compact computing platform designed for multi-SOM configurations, offering a balance between size and functionality. It supports up to seven system-on-modules, including the LM3H, CM4, CM5, and M4N, making it adaptable for various applications requiring distributed computing.

With dimensions of 85x56mm, the board is significantly smaller than a standard mini-ITX board, occupying only one-sixth of its size. Despite its small form factor, it integrates an embedded RISC-V Gigabit Ethernet switch, providing network capabilities with OpenSDK support. Its networking capabilities include ACL, SVL, VLAN, and QoS, which support efficient data management in various applications.
