The E22-900T22S is a high quality LoRa wireless module from EBYTE using the SX1262 chip. The E22 series is one of the first wireless modules to adopt Semtech's SX1262 and SX1268 RF chips. This chip provides a variety of modulation methods, such as LoRaTM and traditional GFSK. Its special LoRaTM modulation method increases the communication distance. This module is configured via software for frequencies between 850~930 MHz. The correct antenna has to be used for the programmed frequency. Typical frequencies would be: 868MHz in Europe(EU) 865MHz to 867MHz in India 902MHZ to 928MHz in the US 915MHZ to 928MHz in the Australia 920MHZ to 923MHz in Japan, Malaysia, Singapore, Indonesia These modules are designed and manufactured with quality in mind. High quality capacitors and German Wurth wire wound inductors are used. A temperature compensated crystal oscillator is used for timing, which is critical for low error long distance LoRa communication.
