Features:
One tri-band transceiver operating frequency is internationally accepted ISM band 433/868/915MHz GMSK modulation, anti-interference ability , especially suitable for industrial control applications using DSS + PLL frequency synthesizer technology, high frequency stability excellent sensitivity , to - 100dBm low operating voltage (2.7V), low power consumption, standby only 1uA, low-power devices to meet the requirements of the maximum transmit power of +10 dBm with multiple channels ( up to 170 or more ) , especially to meet the needs of multi-channel work special occasions up to 76.8Kbps work rate
Minimum of external components (only 10 ) , the basic need to debug. As a result of low transmitting power and high receiver sensitivity design, without a permit , the use of open ground distances of up to 1000 m ** specific use of the environment and component parameters.
