Description and Technical Data:
1) Overview/Key Features
The REYAX RYLR998 is an 868/915 MHz LoRa® antenna transceiver module for long-range, low-power wireless communication. It combines a Nuvoton microcontroller with a Semtech LoRa® engine and is controlled through UART AT commands. The module includes a built-in antenna and is intended for embedded IoT, telemetry, industrial monitoring, smart-building, agriculture, metering, and other applications requiring long-distance communication with low power consumption.
Key features include:
- 868/915 MHz LoRa® operation
- Built-in antenna
- Up to 22 dBm RF output power
- RF sensitivity down to −129 dBm
- Excellent interference and blocking immunity
- Smart receiving power-saving mode
- Standard sleep mode
- UART control through AT commands
- Transparent communication mode
- LoRa® mesh-network application support
- 2.3–3.6 V supply operation
- Compact, lightweight module construction
- Operating temperature range from −40 °C to +85 °C
