The LoRa1278-C1 wireless module uses for Semtech's SX1278 device, which adopts LoRa TM spread spectrum modulation frequency hopping technology to achieve efficient receiving sensitivity and strong anti-interference performance. Its communication distance and receiving sensitivity far exceed the current FSK and GFSK modulation. Multiple transmitted signals occupy the same channel without being affected, and it has strong anti-interference performance.Sensitivity up to -139dBmMaximum output power: 20dBmLow receive current: 10.3mASleep current Less than 200nAData transfer rate:@FSK, 1.2-300kbps@Lora TM,0.018-37.5kbpsLora TM, FSK, GFSK, and OOK modulation modes1.8-3.7 V power supply127dB dynamic range RSSI256-byte FIFO with CRC frequency hopping functionBuilt-in temperature sensor and low battery indicatorNon-blocking signalOperating temperature range: -40-+85℃Product Applications:Remote ControlRemote Meter ReadingHome Security Alarm and Remote Keyless EntryIndustrial ControlHome Automation TelemetryPersonal Data LoggingToy ControlSensor NetworksTire Pressure MonitoringHealth MonitoringWireless PC PeripheralsTag ReadersFrequency range: 433MHzColor:As ShownMaterial:PCBPackage Contents:1 * Wireless RF ModuleOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
