As we know LoRA is popular wireless technology used as wide area network for IoT (Internet of things).

LoRA Transceiver module

Figure-1 depicts typical components in a LoRA tranceiver chip. It consists of UART, processor, GPIOs, LoRA protocol stack, LoRA Radio layer, interface buses (e.g. I2C, SPI) etc. Microcontroller Unit is interfaced using UART with LoRA transceiver for monitor and control applications. GPIOs are used to interface any user defined hardware components such as LEDs, Switches etc. LoRA RF layer is interfaced with antenna of different frequency bands such as 433 and 868 MHz. LoRA transceiver requires crystal for running the processor and real time clock.
