RYLR999 REYAX LoRa and BLE 30dBm 20dBm Range Transceiver Module EVK

Description

Product Overview

The REYAX RYLR999 Evaluation Kit (EVK) is engineered to provide developers with a versatile platform that merges high‑output LoRa® technology and Bluetooth Low Energy (BLE) capabilities into a single, compact module. Operating at 868 MHz or 915 MHz for LoRa and 2.4 GHz for BLE, the board delivers up to 30 dBm of RF power for LoRa and 20 dBm for BLE, ensuring reliable long‑range communication even in challenging environments. The module is built around the Semtech LoRa engine, renowned for its low‑power, high‑sensitivity performance, while the BLE subsystem leverages a transparent mode that can convert LoRa packets into BLE frames, enabling seamless interoperability between sub‑GHz and 2.4 GHz networks.

Physically, the EVK measures 13.54 × 0.91 × 0.83 inches and weighs just 1.76 ounces, making it suitable for integration into a wide range of embedded systems, from handheld devices to industrial sensor gateways. The board includes a UART interface for straightforward serial communication, a set of programmable AT commands for rapid prototyping, and a dedicated OTA (Over‑The‑Air) update mechanism that allows firmware upgrades via the BLE link without the need for physical access. Power consumption is optimized for battery‑operated deployments, with configurable sleep modes that can reduce draw to microamp levels when the radio is idle.

Beyond the core radio functions, the RYLR999 EVK provides a rich set of peripherals: a 3.3 V regulator, status LEDs, a reset button, and a set of GPIO pins that can be repurposed for sensor inputs, actuator control, or additional communication interfaces. The board’s layout follows industry‑standard design guidelines, ensuring signal integrity and minimizing electromagnetic interference. All components are sourced from reputable manufacturers, and the board undergoes rigorous testing to meet the specifications listed in the product data sheet, including compliance with regional RF emission standards.

Usage

The RYLR999 EVK is ideal for a broad spectrum of Internet of Things (IoT) applications. In smart agriculture, the high‑power LoRa link can transmit sensor data across several kilometers of farmland, while the BLE channel enables local data collection on a farmer’s mobile device. In industrial automation, the module can serve as a bridge between legacy equipment that communicates over BLE and modern LoRa‑based mesh networks, facilitating real‑time monitoring and predictive maintenance without extensive rewiring.

Urban developers can leverage the dual‑radio capability for smart city projects, such as environmental monitoring stations that send air‑quality metrics via LoRa to a central server, yet allow on‑site technicians to retrieve detailed diagnostics through a BLE‑enabled tablet. The AT command set simplifies integration into existing firmware, allowing developers to issue commands like AT+SEND or AT+JOIN without writing low‑level driver code. OTA updates further reduce field service costs by enabling remote firmware upgrades, ensuring devices stay up‑to‑date with the latest security patches and feature enhancements.

FAQ

What frequency bands does the RYLR999 support?

The module operates on the 868 MHz or 915 MHz bands for LoRa communication, depending on regional regulations, and on the 2.4 GHz ISM band for BLE. Users can select the appropriate band during configuration via AT commands.

Can I update the firmware without opening the device?

Yes. The EVK includes an OTA (Over‑The‑Air) update feature that works through the BLE interface. By sending the new firmware file from a smartphone or PC using the provided REYAX app, the module can be reprogrammed without any physical connection.

How does the BLE transparent mode work?

In transparent mode, the BLE radio forwards LoRa packets as BLE frames, allowing a BLE‑enabled device (such as a smartphone) to receive data originally transmitted over the sub‑GHz LoRa link. This simplifies data collection in mixed‑technology networks.

What power consumption can I expect in sleep mode?

When placed in deep sleep, the module’s current draw drops to below 5 µA, making it suitable for battery‑powered deployments that require years of operation without maintenance.

Is the EVK compatible with popular microcontroller platforms?

Absolutely. The UART interface follows standard 3.3 V logic levels, and REYAX provides example libraries for Arduino, STM32, ESP32, and other common development boards, enabling quick integration into existing projects.
