The LoRa Mini Dev is an easy prototyping board for LoRa Mini. It can be programmed directly from the onboard USB port with the Arduino IDE and comes with numerous Pins for hooking up a lot of sensors.
The LoRa Mini is a small IoT development board offering 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 helps users to turn an idea into a practical application quickly and easily and makes the Internet of Things a reality. It is easy to program, create and connect your things everywhere.
LoRa Mini is based on the HopeRF SX1276/SX1278 chipset, allowing 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 minimizing current consumption. The LoRa Mini targets professional wireless sensor network applications such as irrigation systems, smart metering, smart cities, smartphone detection, building automation, and so on.
LoRa Mini is an Arduino compatible board based on the popular ATmega328P, a low-power CMOS 8-bit micro-controller based on the AVR® enhanced RISC architecture. LoRa Mini is also open source, user can easily program it using the Arduino IDE.
