1 Introduction
1.1 Brief Introduction
E220-400M30S is 1W module developed independently
based on new generation of LoRa
TM
RF chip LLCC68 from
Semtech. LLCC68 is suitable for 433MHz and 470MHz 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 410~493MHz.
Because the module is a pure RF transceiver module, it needs to use MCU driver or special SPI debugging tool.
