The printed-circuit board features a gigabit Ethernet port, power barrel, and five slots to house the Raspberry Pi Compute Module 3s. The board delivers power and connectivity to the Pi.
The board will also be useful to miniNodes, which provides server hosting based exclusively on low-powered Arm servers using a range of single-board computers, including Raspberry Pi, 96Boards, HiKeys, Pine64s, and Odroids.
It built the carrier board with GumStix and the help of Arm's innovator program, with the aim of making it easier for developers using Docker, Kubernetes, OpenFaaS, and Minio to build cable-free cluster computing projects.
MiniNodes says it will use the carrier board to engineer a five-node 'hosted cluster' product on a private LAN for testing Docker, Swarm, and Kubernetes applications.
The board was originally designed to reduce manual work in deploying lots of Raspberry Pi devices, but the company thought there'd be a market for it among home-automation hackers.
