● I2C
● UART (Serial)
29. Power DistributionPower Distribution
● Supply the BLCs / Motors
● Supply the central controller / Sensors
● Support high currents
● Main switch or battery plugs
● Wires or PCB
39. Practical tipsPractical tips
● Double-check propeller positions and directions
● Double-check Flight Control orientation
● Avoid vibration where possible for stable flight
● Test outside, away from people
● Don't attach the propellers on the motors until
everything is tested!
