EBYTE E32-433T20S SEMTECH’s LoRa solution Long-distance anti-interference transparent transmission LoRa micro module

E32-433T20S-V8.0 is a radio frequency chip based on Semtech: SXI278 SMD wireless serial port module (TTL level”, transparent transmission mode, transmission power 100mW, It works in the 410~441MHz frequency band (the default is 433MHz) and adopts LoRa spread spectrum technology. 16mm It has been steadily mass-produced, and has been widely used in the three-meter industry, the transformation of the Internet of Things, smart furniture, etc. High reliability and transmission efficiency. SX1278 supports LoRaTH spread spectrum technology, LoRaTM direct sequence spread spectrum technology has a longer range The advantages of communication distance and strong anti-interference ability, as well as strong confidentiality.Pass at low speed LLCC68 in the field of credit is a landmark and is favored by people in the industry.

The series The default air rate is 2.4kbps, the transmission power is 20dBm, and the industrial-grade crystal oscillator Ensure its stability, consistency, and accuracy are less than the 10ppm commonly used in the industry.currently field. The module has data encryption and compression functions. The data transmitted by the module in the air. With There is randomness, and through strict encryption and decryption algorithms, the data acquisition is meaningless. The data compression function has the probability to reduce the transmission time, reduce the probability of interference, and improve.
