SA618F30 : 1W Long Range Full Duplex Wireless Audio Module With ESD Protection

  • SA618F30 is a 1W & long range & embedded & full duplex transmission module, combining wireless digital and wireless audio.
  • Users can not only wirelessly transmit data through serial ports, but also achieve wireless transmission of voice through I2S or analog audio interfaces.
  • The module is equipped with a high-speed micro-controller, high-performance RF chip, and high quality voice Codec, and adopts broadband spread spectrum technology. The characteristics are low power consumption, long distance, and flexible frequency adjustment.
  • SA618F30 support maximum 8 channels transmission and reception functions at the same time, as well as maximum 3 level routers for mesh network.
  • This module adopts a highly integrated design, and users only need to connect audio amplifiers, microphones, and speakers externally to easily achieve remote wireless transmission.
  • SA618F30 achieve full duplex through serial port for data transmission.
  • SA618F30 supports (OTA) air upgrade or serial upgrade. The parameters of the wireless module can be set easily by PC software or serial command.
  • SA618F30 is strictly produced and tested using lead-free technology, meeting RoHS and Reach standards.
