Ebyte E32-433T20D-V8 UART/SX1278 410-441Mhz Wireless LoRa Module

Ebyte E32-433T20D-V8 UART/SX1278 410-441Mhz Wireless lora module

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, strong anti-interference ability, and strong onfidentiality. 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 stabilityand consistency, and the accuracy is less than 10ppm, which is generally used in the industry. At present, it has been in stablemassproduction, and has been widely used in the three-meter industry, Internet of Things transformation, smart furniture and other fields.
