Description
The Reyax RYBG211_LITE is a feature-rich Bluetooth 5.1 Low Energy transceiver module designed for developers requiring reliable, long-range wireless connectivity. Its core is a Silicon Labs EFR32-based chipset with a 32-bit ARM Cortex-M33 processor, balancing processing capability with the low-power demands essential for battery-powered IoT nodes.
The module’s standout feature is its +20dBm (100mW) RF output power, significantly extending the operational range compared to standard BLE modules. This is coupled with an integrated PCB antenna and a metal shielding cover that minimizes EMI interference, ensuring stable RF performance in electrically noisy environments. Control and configuration are streamlined through a comprehensive set of vendor-specific AT commands sent via a UART interface.
