1 Introduction

1.1 Brief Introduction

E220-400M22S is an small module developed independently based
on the generation of LoRa
company. LLCC68 is suitable for 433MHz and 470MHz SMD wireless
module and uses industrial 32mhz crystal oscillator.
Compared with the previous generation of LoRa
anti-jamming performance and communication distance have been
further improved. Because of its new LoRa
anti-jamming performance and communication distance are far superior
to the current FSK and GFSK modulation products. The module is
mainly aimed at smart home, wireless meter reading, scientific research, medical, and long distance wireless
communication equipment. The product can cover 410 ~ 493mhz wide applicable frequency range.
Because the module is a pure RF transceiver module, it needs to use MCU driver or special SPI debugging tool.
