RC-RXASK-433-LP
433.92MHz ultra Low-power OOK Receiver Module is a compact, ultra-low-power OOK (On-Off Keying) RF receiver module operating at 433.92 MHz, designed for battery-powered remote control and wireless sensor applications. The module implements a duty-cycled receive architecture that drastically reduces average current consumption while maintaining high RF sensitivity and stable operation.
Duty-Cycle Receive Operation To minimize power consumption, the receiver operates in a duty-cycled mode, alternating between sleep and RX active windows. Default configuration:
Sleep time: 1000 ms
RX window: 20 ms
Resulting average current is 75µA, ideal for long-life battery. Custom duty-cycle configurations are available on request.
