(4) When PWM is 100%, the corresponding waveform is as follows:
5. Usage Precautions
(1) Power Supply Requirements: Use a 5V charger head for power supply, connected to the Type-C interface.
(2) Special Power Supply Note: If using a power bank for supply, a load resistor needs to be connected in parallel.
(3) Physical Protection: Handle with care, avoid impact or forceful shocks.
(4) Environmental Protection - ESD: Take precautions against electrostatic discharge (ESD) to avoid component damage.
(5) Environmental Requirements: Protect from moisture and water; avoid exposing the device to damp conditions or liquids.
