You’ll be able to roll it around and stream live FPV video to your phone as you drive it. In this video, I show you exactly how to assemble, wire up, and program the whole thing step-by-step. 👇 All the files - code, schematics, PCB gerbers, and part list are linked below so you can start this project right away.
