Frequently Asked Questions

What is the difference between ASK and FSK modules?

ASK (Amplitude Shift Keying) varies the amplitude of the signal to transmit data and is simpler and more cost-effective. FSK (Frequency Shift Keying) changes the frequency and offers better noise immunity and longer range, making it ideal for industrial environments.

Are EEant modules FCC and CE certified?

Yes, all EEant RF modules are fully compliant with FCC and CE regulations, ensuring legal operation in North America, Europe, and most global markets.

Can I get custom frequency or power options?

Yes, EEant offers OEM and ODM services. We can customize frequency, output power, modulation, pinout, and packaging based on your application needs.

What applications are these modules used in?

Our modules are widely used in garage door openers, remote keyless entry, industrial automation, home security systems, motorized gates, lighting controls, and telemetry systems.

Do you provide technical support?

Yes, EEant provides full technical documentation, reference designs, and engineering support for integration and troubleshooting.
