Hi all, I just launched my open source modular flight control system called Polystack. You can find more info at https://chickadee.tech including links to the Kicad files. Polystack allows you to take a basic flight control setup: power board, flight control board and receiver board and expand it however you like. Current extras are MicroMinimOSD cradle, MicroSD card connected via SPI and a dual serial breakout board for use with a GPS for example.
Its not a Pixhawk family member yet, but I’d like to brainstorm how to make a mod for Pixhawk. I’m also talking with the iNav folks about what they need for autonomous flight such as magnetometer, barometer and GPS connections. Any suggestions? Does this sound interesting?
