[Introduction]：E32 series are UART wireless modules based on SX1276/SX1278 RF IC of SEMTECH with transparent transmission and LoRa spread spectrum technology. The modules 3.3V TTL output. SX1276/SX1278 support LoRa TM technology, The LoRa TM DSSS (direct sequence spread spectrum) technology features long range and strong anti-interference as well as strong data confidentiality. SX1276/SX1278 are considered as a milestone in terms of low speed data communication.
