Introduction

The E22-400MM22S is an ultra-compact LoRa SMD module based on the SX1268 chip, designed for the 433MHz and 470MHz bands. The module employs LoRa modulation technology, offering significant improvements in anti-interference performance and communication range compared to traditional modulation schemes. It covers a wide frequency range of 410~493MHz, maintains backward compatibility with SX1278 and SX1276 series chips, and features a high-precision 32MHz crystal oscillator. This module is a pure RF transceiver module that requires a microcontroller to operate or a dedicated debugging tool.
