Reyax RYWB116 2.4GHz Ultra Low Power Wi-Fi & Bluetooth 5.0 Module

The RYWB116 operates from a wide voltage range of 1.75V to 3.6V DC, making it directly compatible with single-cell Li-ion batteries (3.7V nominal) and 3.3V logic systems. Ensure your power source can supply peak currents up to 400-500 mA during high-power RF transmission events for stable operation.

Communication is primarily via a UART interface using AT commands. Configure your host MCU's UART to one of the supported baud rates between 9600 and 921600 bps. The module also offers an SPI interface for higher-speed data transfer. Refer to the Reyax datasheet for the specific command set and pinout for initial configuration and network connections.

Yes, the RYWB116 supports concurrent operation of Wi-Fi and Bluetooth 5.0 protocols. Its co-existence management allows it to function as a Wi-Fi client or access point while simultaneously advertising or connected as a BLE peripheral. This is ideal for scenarios like using BLE for device setup and Wi-Fi for main data uplink.

The module is rated for up to 200 meters line-of-sight, leveraging its +21 dBm transmit power and high receiver sensitivity. To maximize range, ensure a stable 3.3V power supply during transmission and avoid physical obstructions. The integrated antenna is optimized for this performance; using an external antenna via a connector is not standard on this variant.

Absolutely. Its key feature is ultra-low power consumption with multiple software-controlled sleep modes. You can put the module into deep sleep when idle, waking it via host MCU control or internal timers. Typical average current consumption can be reduced to microamps, making it excellent for long-life battery applications like remote sensors.
