Chengdu Ebyte Electronic Technology Co., Ltd. E22-900M22S User manual 1. Overview 1.1 Introduction The E22-900M22S is based on the SX1262, a new generation of LoRaTM RF chip manufactured by Semtech, USA. It is an ultra-small and self-developed 915MHz SMD LoRaTM wireless module. Because it adopted the original SX1262 as main core, so the anti-interference performance and communication distance have been further improved compared to the previous generation LoRaTM transceiver.

Basic Operation 4.1 Hardware Design SN 1 Brief Connection between Module and Single Chip Microcomputer The IO0、IO1、IO2、IO3 in MCU means the IO port of MCU. DIO1、DIO2 is the normal IO port, which can be configured to multiple function. The DIO2 can 2 connect with TXEN，but not with the IO port of MCU. It’s used to control RF switch, see more details in SX1262 datasheet. Also It can be floated when not in use.
Chengdu Ebyte Electronic Technology Co., Ltd. E22-900M22S User manual parts with large electromagnetic interference. High-frequency digital traces, high-frequency analog traces, and power traces must be avoided under the module.
Chengdu Ebyte Electronic Technology Co., Ltd. E22-900M22S User manual 5.2 Module is easy to damage Please check the power supply and ensure it is within the recommended range. Voltage higher than the peak will lead to a permanent damage to the module. Please check the stability of power supply and ensure the voltage not to fluctuate too much. Please make sure anti-static measures are taken when installing and using, high frequency devices have electrostatic susceptibility.
