If you are looking for long distance and easy to use serial wireless module, you have got it. This wireless serial port communication module is a new-generation multichannel embedded wireless data transmission module. Its wireless working frequency band is 433.4-473.0MHz, multiple channels can be set, with the channel stepping of 400 KHz, and there are 100 channels in total. The maximum transmitting power of module is 100mW (20dBm), the receiving sensitivity is -117dBm at baud rate of 5,000bps in the air, and the communication distance is 1,000m (1KM) in open space.
Note: This is a transceiver (Transmitter and Receiver) module, you need 1 pair of this module for wireless communication.
