The SRX882 is a 433 MHz RF receiver module for receiving simple wireless data in the 433.92 MHz ISM band. It is typically used with a matching 433 MHz transmitter and provides a digital baseband output for a microcontroller to decode OOK/ASK-style signals.
| Pin | Signal | Description |
|---|---|---|
GND |
ground | Ground return for the receiver power and data interface. |
DATA |
data | Digital OOK/ASK demodulated data output to a microcontroller input. |
CS |
enable | Receiver enable/chip-select control; tie high to VCC for normal receiving. |
VCC |
power | Positive supply input for the 433 MHz receiver module, typically 3.3–5 V. |
GND.1 |
ground | Ground connection near the antenna feed, tied to module ground. |
ANT |
analog | 433 MHz antenna connection for receiving RF signals. |
ANT.1 |
analog | Alternate 433 MHz antenna solder point connected to the antenna feed. |
