Explanation on the Open-Source Issue of the Radiolink Mini Pix Flight Controller
Basing on the APM open source, RadioLink flight controller Mini Pix is developed with software algorithm of damping vibration and the hardware redesigned to achieve “Alt-hold at super low height” and “Stable flight at super high speed” so that Mini Pix applies to various of models including helicopter/fixed wing/multirotor/cars/boats and different fields such as transportation, agriculture, etc. As more and more overseas users have positive feedback about Mini Pix, the APM team approached us, and we provided them our hardware circuit and files in June 2017. The APM team has developed the open-source firmware based on RadioLink Mini Pix hardware for the Mini Pix users.

To flash firmware
If the RadioLink Mini Pix is used for development, it is advised to flash the APM open-source firmware version 3.6.0 or above. If used for RC fun//building models, choose RadioLink firmware version downloaded in RadioLink Mission Planner. Compared with the open-source firmware, firmware developed by RadioLink has better stability with the software filter algorithm added.
A. Flash Open-Source Firmware
Click to flash the firmware in the open-source Mission Planner downloaded via:
