5pcs RX531 433MHz Lead-free Environment-friendly Wireless Receiver Module High Sensitivity Super Heterodyne Super Anti-jamming 2.2V-5V DC
Tax included.
Features:
The RX531 receiving module is a wireless receiving module based on the super-disturbing interference chip WL531R. It is a UHF ASK receiving and demodulating machine that supports ASK and OOK modulation. The receiver module has high sensitivity (-112dBm) and 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 other circuits, which can optimize the signal to a large extent.
- Support ASK/OOK modulation mode, the receiving sensitivity reaches -112dBm;
- Adopt environmentally friendly materials and production and processing technology, can pass ROHS environmental certification
- Good selectivity and stray radiation suppression, easy to pass CE/Fcc international certification;
- Good local oscillator radiation suppression capability, multiple receiver modules can work together (ie, single-shot and multi-receipt) without interfering with each other, and use together does not affect the receiving distance;
Operating frequency: 433.92 MHz, bandwidth about ± 150KHz;
Power supply voltage input range: 2.2V-5.0V;
Temperature range: -40-85 ° C
Size: 23.5 × 9 × 1mm
| Number | symbol | name | Description |
| 1 | ANT | Antenna pin | RF signal output, directly connected to the antenna |
| 2 | GND | Power ground pin | Power ground, can be connected to the antenna housing shield |
| 3 | DO | Data output pin | When the module receives the carrier of the corresponding frequency, the pin outputs a high level; |
| 4 | DO | Data output pin | When the module does not receive the carrier of the corresponding frequency, this pin outputs a non-standard square wave. |
| 5 | GND | Power ground pin | Power ground |
