This product has an SX1301/SX1308 baseband processor and two SX1257/SX1255 RF frontend chips, and peripheral circuits onboard. It could listen on multiple channels and decode packets sent with different LoRa spreading factors simultaneously. LoRaGo PORT is a good alternative to the well-known IMST iC880a. The hardware is basically the same as iC880a except it is more compact in size. This concentrator module is supposed to connect to a host controller via SPI interface. A host controller could either be an MCU with an SPI interface or a PC with a USB to SPI converter located between the concentrator and PC. All the RF jobs are done within this concentrator module and the user could focus on high-level software development. HAL source files are provided by Semtech who is the manufacturer of the baseband processor.
