1.Overview
1.1 Introduction
The E22-900M30S is based on the SX1262, a new generation of
LoRa
TM
RF chip manufactured by Semtech, USA. It is an ultra-small
and self-developed 868MHz
、
915MHz SMD LoRa
TM
wireless module.
Because it adopted the original SX1262 as main core, the PA and
LNA is built-in also based on the previous one, which makes the
maximum transmission power to 1W, 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
TM
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 850~930MHz 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.
