Description and Technical Data:
1) Overview/Key Features
The REYAX RYLR498 is a 426/433/490 MHz LoRa® antenna transceiver module for long-range, low-power wireless communication. It combines a Nuvoton MCU with a Semtech LoRa® engine and is controlled through UART AT commands. The module is designed for embedded IoT, industrial monitoring, telemetry, metering, agriculture, smart-building, and other applications requiring robust low-data-rate wireless communication.
Key features include:
- 426/433/490 MHz regional frequency support
- Long-range LoRa® spread-spectrum communication
- RF output power up to +22 dBm
- RF sensitivity down to −129 dBm
- Proprietary LoRa® communication protocol
- UART interface with AT-command control
- Transparent communication mode
- Smart receiving power-saving mode
- Standard sleep mode
- LoRa® mesh-network capability
- Up to 65,535 network nodes
- Built-in antenna
- Low-power operation
- Operating temperature from −40 °C to +85 °C
- Operating voltage from 2.3 V to 3.6 V
- FCC, CE, NCC, and IC certification references for the product family
The RYLR498 provides the same general functions as the RYLR998 but is intended for 426/433/490 MHz applications rather than 868/915 MHz operation. The applicable frequency must be selected according to local radio regulations.
