LoRa Wireless Module Development Board, Ultra-Long Range Spread Spectrum, High Sensitivity, UART 3.3V for IoT and Remote Sensing

This LoRa wireless module development board is based on the SX1278 chipset, designed for ultra-long range spread spectrum communication. It supports stable data transmission up to 15 km with a constant +20 dBm / 100 mW output even under voltage fluctuations. The module offers high sensitivity of -148 dBm and half-duplex SPI communication, ensuring reliable signal reception over long distances. It features programmable modulation with selectable GFSK, MSK, GMSK, LoRa, and OOK modes, adjustable bit rate up to 300 kbps, and a 127 dB RSSI dynamic range. Smart signal processing includes automatic detection, CAD mode, high-speed AFC, and a packet engine supporting up to 256 bytes. The compact dual-row stamp-hole patch design allows easy integration. A shielded enclosure and compatibility with spring antenna (RA-01) or external antenna (RA-02) enhance flexibility. Note: Minor variations in appearance, color, or printed text may occur between batches, which do not affect performance.
