* 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 descriptions. The connectors and ports are populated to pin-headers on the NEO Core. The NanoPi NEO Core has ESD protection for its 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 popular Allwinner H3 SoC and has onboard 256M/512M DDR3 RAM. FriendlyElec offers  models with three eMMC options: 8GB/16GB/32GB and one that doesn't have eMMC at all.
* FriendlyElec migrated UbuntuCore with mainline kernel 4.14 for it.
* FriendlyElec develops a [[Mini Shield for NanoPi NEO Core/Core2]] which has the same form factor as the RPi 3. When a NanoPi NEO Core is connected to this Mini Shield the whole assembled module can be well fit into a common RPi 3's case.

:'''Note:'''
::# SYS_3.3V: 3.3V power output
::# VVDD_5V: 5V power input/output. When the external device’s power is greater than the MicroUSB's the external device is charging the board otherwise the board powers the external device. The input range is 4.7V ~ 5.6V
::# All pins are 3.3V, output current is 5mA
