4 Channel Wireless RF Remote Control Module 315MHz | Transmitter and Receiver Non-Locking

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.
