The SA618F22-C1 is an upgraded wireless digital and audio all-in-one full-duplex transmission module from NiceRF, supporting 8-channel concurrent high-quality calls. Users can not only achieve wireless data transmission via the serial port but also transmit voice signals through I2S digital audio or analog audio interfaces.

The PA01F39 module is a high-performance FEM module operating in the 400-480MHz frequency range, integrating various RF functionalities. It features a built-in power amplifier (PA) supporting input power up to 30dBm and delivering output power exceeding 39dBm. Additionally, it includes a low-noise amplifier (LNA) circuit and an antenna switch. With its stamp hole package design, the module is compact and easy to embed, significantly reducing the complexity of developing high-power wireless modul

The LoRa1121F33-1G9, like the LoRa1121, utilizes SEMTECH's LR1121 chip, a low-power, long-range LoRa transceiver. It supports LoRa, (G)FSK modulation, the Sigfox protocol, and LR-FHSS technology with strong anti-interference capabilities. Additionally, it is compatible with the LoRaWAN communication protocol, enabling its use as a LoRaWAN node.

LoRa1121F33-1G9 module is built on SEMTECH's LR1121 chip, an ultra-low power, long-range LoRa transceiver supporting Sub-GHz and satellite-connected S-band communication. The LoRa1121F33-1G9 supports LoRa, (G)FSK modulation
