I’ve assembled a list of useful single-board computers (SBCs) for use in home labs. They are essentially low-power computers useful for lightweight tasks and experimentation. I’ve used them (and still do) for certain tasks, especially when I’ve wanted to experiment with various things on the ARM64 platform. FriendlyARM Nano-Pi M4 (6 ARM64 cores, 2/4GB LPDDR3/LPDDR4 RAM) – a handy board for storage applications. It features a PCI Express interface, allowing for multiple SATA ports using the SATA hat or an NVMe drive using the NVMe hat.
