Feature:

●Working voltage: 2.4V-3.7V
●Industrial-grade active crystal oscillator, suitable for industrial sites with complex environments
●Working frequency band: 410-525MHz
●Transmitting power: 19±1dBm(max)
●Ultra-high receiving sensitivity: -136±1dBm(@250bps)
●Ultra-long effective communication distance: [email protected] (urban highway environment, non-wilderness environment)
●Using spread spectrum technology communication, the same urban and industrial application environment, the performance is better than the radio frequency products that use traditional modulation methods (FSK, 2-FSK, 4-FSK, GFSK, PSK, ASK, OOK, etc. ). The advantages are particularly obvious in a noise environment (near strong interference sources such as in the electric meter, near the motor, and natural shielding environments such as elevator shafts, mines, and basements)
●High confidentiality, using LoRa modulation method, traditional wireless equipment cannot obtain and analyze it
●High concealment, normal communication is still possible when the average power in the band is lower than the noise floor
●Adopt LoRa modulation method, compatible with and support FSK, GFSK, OOK traditional modulation method at the same time
●Support hardware frequency hopping (FHSS), combined with LoRa spread spectrum technology, can achieve superior communication concealment and security
●Low power consumption: receiving current ≤13mA; sleep current ≤2uA; CAD function is provided, which separates calculation and signal reception, and further optimizes the power consumption of the wake-up window (calculated current is about half of the receiving current)
●SPI communication interface, can be directly connected to various single-chip computers, software programming is very convenient
