The __NanoPi Fire3__ is a 7.5cm x 4cm Microcontroller (slightly larger than a Raspberry Pi Zero) using a 1.4GHz Octa-Core Cortex-A53 with 1GB DDR3 RAM, with its CPU being a S56818 (Samsung) 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.
At line 17 added 73 lines
Note that when using Armbian, the {{armbian-config}} utility can be used to set most system configuration, including a static IP address.
!! Raspberry Pi Compatibility
The GPIO pins are configured differently to the Raspberry Pi so that Pi hats and devices that connect directly to the GPIO pins won't necessarily work (notably I²C devices). This can be worked around, see below under ''Fire3 GPIO Pinout''.

!! 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. Most I²C software on the Pi uses pins 3 and 5, which are assigned to I²C __bus #1__, whereas on the Fire3 those two pins are assigned to __bus #0__.
On the Fire 3 __I²C Bus #1's SDA and SCL pins are pins 27 and 28 respectively__ rather than pins 3 and 5 as on the Raspberry Pi, so if you get your 3.3v and ground from somewhere on the GPIO bus and SDA and SCL from pins 27 and 28 you can use Pi I²C devices without resorting to altering Python library code (as most seem hard-coded on bus 1, a generally safe assumption).
%%information
__%%(font-size:large)Grumble...%%__ \\
Why FriendlyArm (who make the Fire3) and [Orange Pi] alter the locations of their I²C bus pins and still claim [Raspberry Pi] [GPIO] compatibility is a bit of a mystery. Sadly, on the Orange Pi there are no extant pins for I²C bus #1 at all. There may be some way of initialising a new bus in software and reassigning pins to be compatible with the Pi but that's beyond me (or my interest, frankly).
