Solar Wireless Communication Module XN719D

The chip integrates RF transceiver, frequency generator, crystal oscillator, modem and other functional modules, and supports one-to-many networking and communication mode with ACK. Transmit output power, working channel and communication data rate can all be configured. The chip integrates multiple peripheral chip resistance and capacitance sensing devices into the chip;

The receiving sensitivity of 250K / 1M / 2M bps mode is -93 / -87 / -83dBm; the maximum transmit output power is 13dBm, The open communication distance is close to 100m; the anti-interference performance is good, the adjacent channel rejection of the receiving filter is high, and the receiver selectivity is better;

The working current of transmitting mode (2dBm) is 19mA; the working current of receiving mode is 15mA; Sleep current is 2uA;

The overall size is 23.5*15.5*3.5mm, and the pin definition is simple, which has minimal impact on the motherboard design.
