1 Overview

1.1 Introduction

E22-900M33S is independently developed based on the new generation
LoRa TM radio frequency chip SX1262 produced by Semtech in the United States .
It has a maximum power of 2 W and is suitable for 433 / 470MHz patch-type
LoRa wireless modules . It uses an industrial-grade high-precision 32MHz
TM
crystal oscillator.
Since the imported SX1262 is used as the core of the module, a power
amplifier ( PA) and a low noise amplifier (LNA) are built-in on the original basis ,
so that the maximum transmit power reaches 2 W and the receiving sensitivity is
further improved. In the overall communication The stability is greatly improved
compared to products without power amplifier and low noise amplifier. Compared with the previous generation LoRa
the anti-interference performance and communication distance have been improved, further widening the gap with products with FSK
and GFSK modulation methods . This product can cover an ultra-wide applicable frequency range of 850 to 930 MHz and is backward
compatible with SX1278 and SX1276.
Since this module is a pure radio frequency transceiver module, it needs to use an MCU driver or a dedicated SPI debugging tool.
