Description

●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: 5Km@250bps (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
