I Chengdu Ebyte Electronic Technology Co, Ltd. E22-400M30S User manual
1. Overview
1.1 Introduction
The E22-400M30S is based on the SX1268, a new generation of
LoRa™ RF chip manufactured by Semtech, USA. It is an ultra-small and
self-developed 433MHz, 470MHz SMD LoRa™ wireless module.
Because it adopted the original SX1268 as main core, the PA and LNA is
built-in also based on the previous one, which makes the maximum
transmission power to IW, at the same time, the receive sensitivity is also
further improved. The overall communication stability is greatly improved

compared to the products without power amplifiers and low noise amplifiers. The anti-interference performance and
communication distance have been further improved compared to the previous generation LoRa™ transceiver, and far
superior to the current FSK and GFSK modulation products. This products obtained FCC, CE and RoHS certification
already so users do not need to worry about the performance. Adopted industrial grade high precision 32MHz crystal, the
product can cover an ultra-wide frequency range of 410~493MHz and is backward compatible with SX1278 and
SX1276.
Since the module is a RF transceiver module only, users need to use the MCU driver or use a dedicated SPI debug tool.
