The Dragino LoRa mini dev featuring LoRa® technology is the easy prototyping board for LoRa® technology.  It has a USB port which let user to easy program module via Arduino IDE. it also has pin slot for easy to connect sensors. 

LoRa Mini dev is a small IoT development board offers a very compelling mix of long range, low power consumption and secure data transmission.It is designed to facilitate beginners and developers to quickly learn LoRa and IoT technology. It help users to turn the idea into a practical application and make the Internet of Things a reality. It is easy to program, create and connect your things everywhere.

LoRa Mini dev is based on SX1276/SX1278 allows the user to send data and reach extremely long ranges at low data-rates.It provides ultra-long range spread spectrum communication and high interference immunity whilst minimising current consumption.It targets professional wireless sensor network applications such as irrigation systems, smart metering, smart cities, smartphone detection, building automation, and so on.

LoRa Mini module featuring LoRa® technology is an Arduino compatible board based on ATmega328P, a low-power CMOS 8-bit microcontroller based on the AVR® enhanced RISC architecture.LoRa Mini is also open source, user can easily program it using the Arduino IDE.
