Description DET340 is a ultra long transceiver module designed for operation in the unlicensed ISM(Industrial Scientific Medical) bands based on RFIC SX127X from SEMTECH. It adopts LoRa spread modulation/demodulation to makes DET340 module easy to realize the robust and reliable ultra long range wireless link. The module can be configured to work in different channels. With the high efficient looped interleaving EDAC(Error Detection and correction) coding. DET340 keeps in advance in error correction and coding efficiency over normal FEC(Forward Error Correction) coding. Because of its high reliability in correction, DET340 can filter error and fake information automatically and realize truly transparent wireless link, which makes it very suitable in the rigid communication environment. DET340 integrates dual 256 bytes buffer. When the buffer is empty, user can interface nearly 256 bytes data at a time and even limitless data transfer can be achieved as long as Air data rate is configured to be faster than UART data rate (MCU to RF module). DET340 provides standard UART/TTL interface. User can choose six data rates and three parity checks which make DET340 possibly tailor-made for different applications.
