The SX1278 433MHz RA-01 LoRa Wireless Transmit Module is a compact long-range RF communication module based on Semtech LoRa modulation technology. It delivers reliable wireless communication with high sensitivity of up to -148dBm and +20dBm (100mW) RF output power for extended transmission distances up to 15km in ideal conditions. Supporting LoRa, FSK, GFSK, MSK, GMSK, and OOK modulation modes, the module offers excellent anti-interference performance while maintaining low power consumption. It features half-duplex SPI communication, programmable bit rates up to 300kbps, 127dB RSSI dynamic range, automatic RF signal detection, CAD mode, ultra-high-speed AFC, and packet CRC support up to 256 bytes. The shielded compact SMD package with a spring antenna makes it suitable for IoT devices, wireless sensor networks, smart agriculture, telemetry, remote monitoring, and industrial automation requiring stable long-distance wireless communication. Features: LoRa spread spectrum modulation technology Up to 15km wireless transmission range High receiver sensitivity up to -148dBm +20dBm (100mW) RF output power Supports LoRa, FSK, GFSK, MSK, GMSK & OOK Half-duplex SPI communication interface Automatic RF detection with CAD mode Shielded compact module with spring antenna Specifications: Model: RA-01 RF Chip: SX1278 Operating Frequency: 433MHz Modulation: LoRa, FSK, GFSK, MSK, GMSK, OOK Communication Distance: Up to 15km RF Output Power: +20dBm (100mW) Receiver Sensitivity: Down to -148dBm Communication Interface: Half-duplex SPI Programmable Bit Rate: Up to 300kbps RSSI Dynamic Range: 127dB CRC Packet Length: Up to 256 Bytes Package Type: Double-row Stamp Hole SMD Dimensions: 21 x 12 x 10 mm Weight: 3 g Package Includes: 1 x SX1278 433MHz Ra-01 LoRa Wireless Transmit Module 1 x Spring Antenna
