How to build your own mini-drone with the STEVAL-DRONE02 and STEVAL-
FCU001V2
Introduction
The
STEVAL-DRONE02
mini drone companion kit features motors, propellers, plastic frame, and battery that you need to
assemble your own mini-drone.
The flight controller unit is not included in this kit. To build a fully functional drone, or unmanned aircraft system (UAS), you need
to use the
STEVAL-FCU001V2
control board with the set of spare parts included in the
STEVAL-DRONE02
kit. To complete the
hardware and firmware aspects of the mini-drone kit, use the
STSW-FCU001
firmware.

UM3117 Overview Overview Features of the STEVAL-DRONE2 kit • Four motors: 3.7 V, 85x20 mm coreless DC motors • Two clockwise and two counterclockwise 65 mm propellers, plus a couple of spares • LiPo 3.7 V/600 mAh battery with a maximum discharge current of 30 C •... -
Page 4: Figure 3. Four Motors Rotating At The Same Speed
UM3117 Overview Figure 3. Four motors rotating at the same speed When two diagonal motors rotate more quickly than the other two motors, the drone rotates along its yaw axis. If the counterclockwise motors spin faster, the drone rotates in a clockwise direction (see Figure 4), and vice versa. -
Page 5: Euler Angles
UM3117 Overview Figure 5. Differentiating diagonal motor velocities adjust pitch and roll 2.2.1 Euler angles The flight control unit (FCU) uses Euler angles to determine the orientation of a drone and produce desired balance and movement. The FCU algorithm compares actual Euler alpha (α), beta (ß) and gamma (γ) angles with target angles to determine the necessary adjustments to the individual motor velocities. -
