Set of useful high quality libraries to make interaction with various hardware / modules / etc simple.
- LoRa library (for devices based on 
SX1276chip), does not implement LoRaWAN. - SHTC3 temperature/humidity no that high precision I2C sensor.
 - SHT3X temperature/humidity high precision I2C sensor.
 - SI7021 temperature/humidity high precision I2C sensor.
 - VEML6030 ambient light high precision Ambient Light I2C sensor.
 - Debug - tiny size helpers to print text / values through UART
 - Ring Buffer - simple set of macros to work with ring (circular) buffer. In favour of *nix 
queue.h. - NanoPB Ring Buffer streams - ring buffer based input/output streams for nanopb.
 - Printf - basic printf() redirector to hUARTx
 
- Super simple way: just copy required files into your STM32 HAL project.. that's it!
 - git submodules
