EBYTE E32-433T20S

E32-xxxT20x series (UART) module is developed based on SEMTECH classic RF chip. It’s transmitting power is 20 dBm, with a variety of transmission modes, working frequency band in 400 and 900 band, LoRa spread frequency technology, TTL level output, compatible with 3.3V IO port voltage. E32-xxxT20x adopts the new generation of LoRa expansion technology, LoRa straight sequence expansion technology has the advantages of farther communication distance, strong anti-interference ability, and strong confidentiality. The default air rate is 2.4 kbps and the transmitting power is 20 dBm, so as to improve the communication stability and extend the communication distance; industrial active temperature filling vibration is adopted to ensure its stability and consistency. At present, it has been stable in mass production, and has been widely used in the three-table industry, Internet of things transformation, smart home and other fields. E32-xxxT 20x strictly comply with FCC, CE, ROHS and other domestic and foreign design specifications, meet the radio frequency related certification, meet the export requirements.
