Aliased from Fire3
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.
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.
