Economical development board based on the ESP32 module for the development of applications or objects connected to the LoRaWan network. Development boards are generally equipped with an OLED screen controlled for an SSD1306 circuit that is very well supported by Arduino libraries.
Choose the radio module that corresponds to your frequency used in your country. Each radio module can be configured in a particular frequency. There is an optimal frequency for each module.
