README
SimpleFC_G/README.mdSimpleFC_G
The SimpleFCv2 with integrated GPS receiver. Together with its 10 DoF IMU, it has full navigation capability.
WARNING: The PCB design has not been fabricated, Use with caution!
Change List (compare to SimpleFCv2)
- A UBlox ZOE-M8Q GPS receiver is added while external GPS receiver can still be used by changing solder jumpers.
- The onboard DC-DC converter is now MP1470, which supports 2~3s Li-Po.
Software
SimpleFC was originally designed to run modified version of AutoQuad, the source can be found in my fork of AutoQuad. In additional, port for PaparazziUAV is in progress. It will make SimpleFC support both fixwing and rotorcraft.

Questions
How big is the SimpleFC PCB?
It measures 50 × 50 mm and has 4 copper layers, 1.6 mm thick.
What parts does the SimpleFC use?
128 parts, built around the SN74LVC245APW, 74LVC1G86Z, AT24C512CN and ICM-20689. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the SimpleFC KiCad files?
From the wangyeee/OpenHardware repository on GitHub, at the commit this page was made from: the board is SimpleFC/SimpleFC.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the SimpleFC design in my own project?
Its repository publishes it under the BSD-3-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
