6.2 RX500 receiving module, WL1.
Description:
Used to receive commands from the remoute control, operating frequency 433.92 MHz.
The RX500 receiving module WL1 is a UHF ASK receiving demodulator, which supports ASK demodulation. The receiving module has high sensitivity (-110dBm),
low power consumption performance (<6mA),
At the same time, it has a high dynamic range (greater than 60dB). The module uses a highly integrated chip, built-in front-end low noise amplifier, mixer, filter,
frequency synthesizer. And so on, the signal can be optimized to the greatest extent.
Used to receive a signal from the radio remote control, to control the operating modes of the device.
