Arduino Uno (Transmitter) with RX470C-V01:

VCC -> 5V (from Arduino) GND -> GND (from Arduino) Data Pin (Usually, this pin is the one used for transmitting) -> Use a digital pin, e.g., Pin 3

ESP32 (Receiver) with RX470C-V01:

VCC -> 3.3V (from ESP32) GND -> GND (from ESP32) Data Pin -> Use a digital pin, e.g., Pin 22
