The NanoPi NEO is a compact single-board computer (40x40 mm) powered by the Allwinner H3 quad-core ARM Cortex-A7 SoC, with 256/512 MB DDR3 RAM. Designed for headless IoT, networking, and embedded projects, it features Ethernet, USB, and 36-pin GPIO. It supports Linux (FriendlyCore, Armbian) via MicroSD. Affordable but prone to overheating, it’s ideal for small-scale servers or clusters with proper cooling.
