NRF905 Wireless Module

NRF905 Wireless Module

Features:
Tri-band transceiver operating frequency for the international ISM band 433/868/915MHz GMSK modulation, anti-interference ability, especially for industrial control applications using the DSS + PLL frequency synthesizer technology, excellent frequency stability, high sensitivity, to achieve - 100dBm low operating voltage (2.7V), low power consumption, standby only 1uA maximum transmit power of +10 dBm with multiple channels (up to more than 170) meet the requirements for low-power devices, in particular, to meet the needs of multi-channel work of special occasions, the work rate up to 76.8 Kbps
External components of at least (10), the basic need to debug. Low transmit power and high receive sensitivity of the design, the use of the license required to apply for open use at distances up to 1000 m ** and the specific use of the environment and component parameters.
