The RYLR684/RYLR689 from Reyax Technology is a cost-effective LoRa and (G)FSK (Gaussian frequency-shift keying) transceiver module that is suitable for long-range wireless applications. The cost-effective LoRa modules are based on a Semtech LLCC68 chip and have a programmable transmission power level from -20dBm to 22dBm. This allows the designers to optimize the range and power of the transmitter for each use case thus reducing the energy consumption of battery-powered devices. The LoRa modules are suitable for a wide range of use cases including asset tracking, smart agriculture, smart buildings, industrial automation and various other IoT applications.

The products have been launched to replace the traditional Frequency Shift Keying (FSK) and Amplitude Shift Keying (ASK) technology that had higher energy consumption. The RYLR684/RYLR689 are suitable for demanding applications with low current consumption. To enhance the sensitivity and achieve better performance, both the modules come with metal covering that protects them against EMI interference, and offer considerably better performance even when surrounded by noise from other devices.

In addition to LoRa, both modules also support the (G)FSK modulation and all major ISM (Industrial Scientific Medical Band) frequency bands. Furthermore, the RYLR684 and RYLR689 separately support the frequency band of 426/433/490MHz and 868/915MHz, which make them usable in various application therefore can be widely used in a variety of applications around the globe. The SMT/DIP option and antenna option design model also help meet designers’ requirements with different usage scenarios. The transmitter module can help meet can be used in a variety of low-powered IoT applications including asset tracking, smart farming, smart buildings, etc.
