Note: If you are using a Lithium Polymer (LiPo) battery, this voltage spec means you need between a
3S and 6S battery. The “S” designation is the number of cells, and each cell is 3.7V. Therefore, a 3S
LiPo is 11.1V, while a 6S battery is 22.2V.
7. Set enough POWER to get the motors to move.
8. Test the full system by rotating the IMU sensor board around each of its three axes.
Make sure each motor is moving when you do so. Motors should spin smoothly when
you move the sensor. A small amount of jitter is normal, due to the magnetic force
between rotors and stators known as “cogging” effect.!
