Description
The R04B 433MHz Wireless Receiver Module is a dedicated RF component engineered for receiving digital commands in simple wireless control systems. It demodulates incoming 433MHz ASK/OOK signals and translates them into discrete CMOS-level logic outputs, making it ideal for pairing with common 4-button remote transmitters.
Built for reliability, the module features a high-sensitivity receiver front-end capable of operating effectively at low power. Its straightforward interface eliminates the need for complex SPI or UART decoding, providing direct, channel-specific digital outputs that can be read by microcontrollers or drive logic circuits directly for applications like remote switching, garage door openers, or basic telemetry links.
