LSN50v2 - Dragino LoRaWAN Sensor Node included 2x12bit ADC, 1x12bit DAC I2C,LPUSART1,USB 18xDigital I/Os

LSN50v2 is a Long Range LoRaWAN Sensor Node. It is designed for outdoor use and powered by Li/SOCl2 battery for long term use, power consumption and secure data transmission.It is designed to facilitate developers to rapidly deploy industrial level LoRaWAN and IoT solutions. LSN50 v2 helps 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.

LSN50v2 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.

LSN50v2 uses STM32l0x chip from ST, STML0x is the ultra-low-power STM32L072xx
microcontrollers incorporate the connectivity power of the universal serial bus (USB 2.0 crystal-less) with the high-performance ARM® Cortex®-M0+ 32-bit RISC core operating at a 32 MHz frequency, a memory protection unit (MPU), high-speed embedded memories (192 Kbytes of Flash program memory, 6 Kbytes of data EEPROM and 20 Kbytes of RAM) plus an extensive range of enhanced I/Os and peripherals.

LSN50v2 is an open source product, it is based on the STM32Cube HAL drivers and lots of libraries can be found in ST site for rapid development.

Default FW in AS923, but it support US915, AU915 and all 900MHz Frequency by loading different FW, it could also support 868MHz if loading 868MHz FW, but there will be slight 0.5-1dB loss here.
