WS8302DLS is a wireless audio module developed by Chengdu Silent Smart Technology with a transmission power of 30dBm.

The module uses LoRa modulation for voice data transmitting and receiving, which greatly improves the communication anti-interference ability and transmission distance.

The module provides four different audio coding rates, the module's air rate is determined by the audio coding rate, the user can change the coding rate according to the actual use of the situation, in order to adapt to a longer communication distance or higher call quality, to facilitate the user's secondary development and integration.

The module supports to modify the RF channel through the serial port, realized by sending configuration commands, and supports to control the transmission, when pulling down the PTT control pin, the module will start the wireless transmission. At this time, the input voice signal will be sent out wirelessly, and the receiver will receive the data and decode it to get the voice through the audio output port.

The module only needs external MIC, voice amplifier and antenna to form a complete multi-party intercom.
