Making a functional remote control

Introduction to RXC6 433MHz Receiver Module

The RXC6 433MHz receiver module is a compact and efficient wireless receiver used for remote control applications. Operating at the 433MHz frequency, it is designed to receive signals from RF remote transmitters, making it ideal for wireless communication in home automation, garage doors, security systems, and DIY electronics projects.

This module is known for its low power consumption, simple interface, and reliable performance over short to medium distances. It works seamlessly with popular encoder ICs such as PT2262, EV1527, and other fixed or learning code remotes, allowing for easy integration into embedded systems and microcontroller projects.

Whether you’re building a custom remote control system or adding wireless capabilities to your electronics, the RXC6 module offers a cost-effective and user-friendly solution.

First, let us introduce you to the schematic and datasheet of the remote control, which you can see in the image below

Pin Descriptions:

• Pin 1: Antenna connection – connect a telescopic antenna to increase the reception range.

• Pin 2: GND (Ground)

• Pin 3: LED indicator for chip status

• Pin 4: Connection for external micro switch

• Pin 5: LED indicator for data status

• Pins 6 to 9: Digital outputs (0 or 1)

• Pin 10: Vcc + (5V power supply)

• Pin 11: GND (Ground)

Buttons:

Reset and Learn Key
This button is used to pair or remove remote controls from the module, as explained below:

• Pairing: Press and hold the key for 2–3 seconds, then press one of the remote control buttons. The remote will be successfully paired and can now control the module.

• Removing All Remotes: Hold the key for about 7 seconds to delete all paired remotes from the module’s memory.

Jumper Pins:

• Jumper 1 (T1):
  When connected, the digital output pins work in momentary mode — the output goes HIGH (1) only while the corresponding remote button is being pressed and goes LOW (0) when released.

• Jumper 2 (T2):
  When connected, the output pins operate in toggle mode — pressing a remote button once sets the corresponding output HIGH (1), and it remains HIGH even after releasing the button. Pressing the same button again sets the output LOW (0).

• Both Jumpers Connected:
  If both jumpers are connected at the same time, all module outputs will be disabled.
