The NanoPi NEO Core(abbreviated as "NEO Core") is an alternative 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 its Micro-usb 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 popular Allwinner H3 SoC and has onboard 256M/512M DDR3 RAM. migrated UbuntuCore with mainline 4.14 for it. develops a Mini Shield for NanoPi NEO Core/Core2 which has the same form factor as the RPi 3.
