Wireless Lora spreading module 433M RF E32-900T20D SX1276 RF chip wireless serial port module (UART) low power transmission
E32-900T20D is a wireless serial port module (UART) based on SEMTECH's SX1276 RF chip.
Product Descriptions
E32-900T20D is a wireless serial port module (UART) based on SEMTECH's SX1276 RF chip. It has multiple transmission modes.working in the 862MHz~931MHz, LoRa spread spectrum technology,TTL output.
SX1276 features LoRaTM,which will bring longer communication distance, and has the advantages of concentrated power density,meanwhile it has a very strong confidentiality. the modules of 20dBm transmitting power adopt industrial grade crystal oscillators to ensure the stability and consistency. E32-900T20D are widely applied in utility meters, loT renovation, smart home, etc. The modules feature data encryption and compression.The data transmitted in air features randomness.air Data Rate(Default 2.4kps).
E32-900T20D strictly follows design standards of FCC, CE, CCC and meets various RF certification requirements for exporting.
