Wireless Lora spreading module 433M RF E32-433T20D SX1278 RF chip wireless serial port module (UART) low power transmission

Product Descriptions

E32-433T20D is a wireless serial port module ( TTL level) based on Semtech's SX1278 radio frequency chip, transparent transmission, working in the 410-441MHz frequency band (default 433MHz)， using LoRa spread spectrum technology.

SX1278 supports LoRa spread spectrum technology. LoRa direct sequence spread spectrum technology has the advantages of longer communication distance,anti-interference ability, and strong confidentiality. SX1278 is a milestone in the field of low-speed communication, and is favored by people in the industry. The default air rate of this series is 2.4kbps , the transmit power is 20dBm, and the industrial -grade crystal oscillator is used to ensure its stability and consistency, and the accuracy is less than 10ppm, which is generally used in the industry. At present, it has been in stable mass production, and has been widely used in the three-meter industry, Internet of Things transformation, smart furniture and other fields.

The module has data encryption and compression functions. The data transmitted by the module in the air is random, and the data interception is meaningless through strict encryption and decrypton algorithms. The data compression function has the posibility toreduce the transmission time. reduce the probability of being interfered, and improve reliability and transmission efficiency.

E32-433T20D strictly abides by FCC, CE, CCC and other domestic and foreign design specifications, meets various RF-related certifications, and meets export requirements.
