2.2.3 Power Amplifier
The QNET VTOL circuit board includes a PWM voltage-controlled power amplifier capable to providing 2 A peak
current and 0.5 A continuous current (based on the thermal current rating of the motor). The output voltage range
to the load is between 0 V and 10 V.
2.2.4 Status LED
The QNET VTOL is fitted with a variety of safety measures that use the Status LED for feedback, see Figure 2.3. In
particular, two digital enable lines (one high, one low) are used to ensure proper system configuration. The system
states are displayed as in Table 2.2. Here, a ∗ indicates any state.
