Receiver 433MHz EV1527 4-channels

Product detailed description

The RX480E-4 is a four-channel 433 MHz receiver with an EV1527 decoder that learns your remote control code and activates one of four logic outputs based on the pressed button. Pairing is performed simply via a button directly on the module, without programming, and paired remotes and the selected mode remain stored even after power disconnection. The outputs can be connected directly to the inputs of an Arduino, ESP32, or other microcontroller, or used to switch larger loads via a transistor or relay module. It is suitable for the remote control of lighting, drives, gates, models, or your own DIY projects.

Specifications:

• Model: QIACHIP RX480E-4
• Frequency: 433.92 MHz
• Encoding: EV1527 (learning code)
• Power supply: 3–5 V DC
• Quiescent Current: ≤ 5 mA
• Receiver Sensitivity: −108 dBm
• Range: approx. 15 m and more (depending on the remote, antenna, and environment)
• Outputs: 4× logic level, active HIGH, max. 10 mA per output
• Operating Modes (selected by the number of presses of the programming button, applies to the entire module):
  • 1× – Momentary (Inching): output is active only while the button on the remote is held
  • 2× – Toggle (Self-Lock): each button press turns the output on, the next press turns it off
  • 3× – Interlocked: output remains on until another button is pressed
  • 4×: 2 toggle channels + 2 momentary channels
  • 5×: 2 interlocked channels + 2 momentary channels
  • 6×: 2 interlocked channels + 2 toggle channels
  • 8×: erase all paired remotes
• Pins (2.54 mm pitch):
  • GND: power ground
  • +V: 3–5 V power supply
  • D0–D3: channel outputs
  • VT: valid signal received indicator (concurrent with red LED)
• Button Assignment (typically for 4-button remotes):
  • D0 – Button D
  • D1 – Button C
  • D2 – Button B
  • D3 – Button A
• Operating temperature: −40 °C to +85 °C
• Dimensions: approx. 28 × 12.3 × 7 mm
• Weight: approx. 3 g
• Suitable remotes:
  • Remote Control KT01-4 433MHz EV1527 4-Channel
  • 433MHz wireless remote EV1527 4-channels
  • Remote Control KB-027C 433MHz EV1527 2-Channel
  • Remote Control KB-027C 433MHz EV1527 1-Channel

Remote pairing:

1. Clear old codes: press the programming button 8×; the red LED will flash 7× and then turn off.
2. Mode selection: press the programming button 1× to 6× according to the desired mode. The LED will flash and remain lit – the receiver is waiting for a signal from the remote.
3. Pairing: press any button on the remote. The LED will flash to confirm the code has been saved.
4. Other remotes can be paired using the same procedure, but the selected mode is common for the entire module.

Package contents:

• 1× RX480E-4 433 MHz receiver with spiral antenna

Note:

• Outputs D0–D3 provide only a logic signal (max. 10 mA) – connect loads such as relays, motors, or LED strips via a transistor or relay module.
• The "Interlocked" mode only makes sense with a remote that has at least 2 buttons.
• If connecting an external LED to the VT pin, use a series resistor.
• This product is not a standalone functional unit and may require professional installation.
• Product images are for illustrative purposes only and may sometimes differ from the actual appearance of the item. However, this does not change their basic properties.
