1 Introduction
1.1 Brief Introduction
E220-900M30S is 1W module developed independently based
on new generation of LoRa
TM
RF chip LLCC68 from Semtech.
LLCC68 is suitable for 868MHz/915MHz SMD wireless module and
uses industrial 32mhz crystal oscillator.
The original imported LLCC68 is used as the core of the
module, a power amplifier (PA) and a low noise amplifier (LNA) are
built on the original basis, so that the maximum transmission power
reaches 1W and the receiving sensitivity is further improved. In the
overall communication Compared with products without power
amplifier and low noise amplifier, the stability is greatly improved.
Compared with the previous generation of LoRa
TM
transceivers, the
anti-interference performance and communication distance have
been improved, further opening the gap with FSK and GFSK
modulation products. The product can cover an ultra-wide frequency range of 850~930MHz.
Because the module is a pure RF transceiver module, it needs to use MCU driver or special SPI debugging tool.
