The NanoPi Fire3 is a 7.5cm x 4cm Single Board Computer (SBC) which hosts a 1.4GHz Octa-Core Cortex-A53 with 1GB DDR3 RAM, with its CPU being a Samsung S56818 SoC. The Fire3 has a CMOS interface to support cameras, 40-Pin GPIO, MicroHDMI, RGB LCD Connector, and Gbps Ethernet.
It can run FriendlyCore, Debian, Android and Armbian.
Given it is only slightly larger than a Raspberry Pi Zero but hosts a 1.4GHz 8-core CPU, it's one of the more powerful small "Raspberry Pi compatible" SBCs available. As for true compatibility, see below.
The Fire3 has been tested by the NZPRG using the Armbian and Ubuntu operating systems. We recommend Armbian.

Fire3 GPIO Pinout#
While it claims to be, the Fire3's GPIO is actually not compatible with the Raspberry Pi, notably the I2C bus is different.
