The Reyax RYLR896 LoRa Transceiver Module is based on LoRa technology, thus, it uses long-range communications technology with a very low power consumption. This transceiver is based on the UHF frequency band which you can change in its configuration files with a USB to Serial cable. In this project, I did not configure the modules manually and. The LoRa module is a wireless communication module developed based on Semtech’s chips. The LoRa module has a small integrated scale, low power consumption, and high sensitivity, which has greatly promoted the development of LoRa. The advantages of LoRa module are mainly reflected in the following aspects:. Pre-Programmed LoRa Modules Fully certified 868/915 MHz modules FCC, IC, RED and ANATEL certified Pre-programmed modules with simple ASCII command interface over UART for ease of use Castellated SMT pads for easy and reliable PCB mounting Proven software along with application examples Learn More: RN2483 868 MHz Module. We are going to test E32-TTL-100. It is a wireless transceiver module, operates at 410 441 MHz (or 868MHz or 915MHz) based on original RFIC SX1278 from SEMTECH, transparent transmission is available, TTL level. The module adopts LORA spread spectrum technology. Supplies: Arduino UNO.
