Chapter 1 Overview
1.1 Introduce
E22-900MM22S is based on the new generation of LoRaTM radio frequency
chip SX1262 produced by Semtech in the United States as the core of the
independent research and development of ultra-small volume, and is
suitable for 868MHz, 915MHz chip LoRaTM wireless module.
Since the original imported SX1262 is used as the module core,
compared with the last generation LoRaTM transceiver, the
anti-interference performance and communication distance are further
improved. Because it uses the new LoRaTM modulation technology, the
anti-interference performance and communication distance are far beyond
the current FSK, GFSK modulation products. This module is mainly aimed
at smart home, wireless meter reading, scientific research and medical, and medium and long range wireless
communication equipment. Because the RF performance and component selection are in accordance with industrial
standards, the product can cover the ultra-wide frequency range of 850~930MHz and downward compatible with SX1278
and SX1276. Use industrial grade high precision 32MHz crystal oscillator.
Since the module is a pure RF transceiver module, MCU driver or special SPI debugging tool should be used.
