Introduction

SA618F22 is an embedded wireless full-duplex transmission module that combines digital and audio functions in one. Users can not only perform wireless data transmission via serial port, but also achieve wireless transmission of voice signals through I2S digital audio or analog audio interfaces. The module integrates a high-speed microcontroller, high-performance RF chip, and power amplifier, and employs wideband spread spectrum technology, featuring low power consumption, long transmission range, and flexible frequency adjustment. The module supports multi-channel concurrent transceiving and multi-level relay long-distance transmission. With its highly integrated design, users only need to connect an audio power amplifier, microphone, and speaker to the module to easily achieve long-range wireless transmission of digital voice. The SA618F22 supports full-duplex wireless data transmission with relay functionality via serial port, supports OTA or serial port firmware upgrade, and allows quick and easy configuration of internal parameters and control of transceiving functions through the serial port. In addition, the SA618F22 is strictly manufactured and tested using a lead-free process, complying with RoHS and REACH standards.
