Frequently Asked Questions

Q: What is the difference between the low-voltage and high-voltage versions of this PWM electronic switch module?

A: The low-voltage version operates at 3.0V–5V and supports up to 2A output current, making it ideal for smaller RC accessories. The high-voltage version operates at 3.0V–30V and supports up to 20A, suitable for more power-demanding applications such as agricultural drone water pumps and larger motor systems.

Q: What type of RC receiver or remote control is compatible with this switch module?

A: This module works with standard two-stage RC remote controls that output a PWM signal. It uses a JR Male control connector (for the 30A version) and integrates directly with most common RC receivers used in drone, model aircraft, and RC vehicle setups.

Q: Can I use this electronic switch module to control a water pump on an agricultural drone?

A: Yes. This module is specifically designed for applications including drone-mounted water pumps and crop protection sprayer systems. Choose the 20A or 30A variant based on your pump's current requirements, and ensure wiring is rated to match the output current to ensure safe operation.

Q: What does the LED indicator on the module mean?

A: A slow-flashing LED indicates the switch is in standby (no output), while a steady (solid) LED light means the switch is actively outputting power. This provides a quick visual confirmation of your module's operating state.
