Who is it for?
Engineers, students and R&D teams who want to build their own cold-storage monitoring node on STM32. All parts are pre-selected for the 920–923 MHz LoRa band (also usable in other AS923 / 915 MHz regions).
Includes free test code for every module (LoRa, sensors, display…) so you can verify the hardware on arrival. For full functionality, add the firmware or the source code.
