The NanoPi NEO Core(abbreviated as "NEO Core") is an NanoPi NEO that works like a CPU board with male pin-headers. It has the same form factor as the NanoPi NEO and same pin s. The connectors and ports are populated to pin-headers on the NEO Core. The NanoPi NEO Core has ESD protection for MicroUSB port and TF card slot. In addition the NEO Core can have an optional onboard eMMC flash which is preferred by industrial customers. The NEO Core uses a Allwinner H3 SoC and has onboard 256M/512M DDR3 RAM.
