The 4 Channel RF Remote Control Transmitter and Receiver Module is a versatile solution for wireless control in robotics, DIY automation, and electronics projects. Operating at 315MHz frequency with stable ASK modulation, this module supports four independent channels, allowing you to control devices such as electric locks, garage doors, fans, or lighting systems.
The included non-locking mode ensures that signals remain active only while buttons are pressed, making it suitable for real-time control applications. Students, hobbyists, and engineers frequently use it in circuit design, graduation projects, and embedded systems due to its compact size and reliable performance.
⚠️ Note: By default, the remote is set to Non-Locking mode. Other modes like Self-Locking or Interlocking require different configurations or models.
🔹 FAQs
Q1: What is the operating range of this module?
With a proper 17cm antenna, the transmission distance can reach 30–50 meters indoors and up to 200 meters outdoors (line of sight).
Q2: Can I change the operating mode?
This model comes with Non-Locking mode by default. For Self-Locking or Interlocking modes, you would need a compatible variant of the module.
Q3: Is the transmitter secure?
Yes. Each remote has a unique fixed code ID that ensures the receiver only responds to known transmitters.
Q4: Does the package include a battery?
No. The remote requires a 12V battery, which must be purchased separately due to shipping restrictions.
