The STMicroelectronics development discovery kit is an 868MHz for Arduino, internet of things. The IoT node allows users to develop applications with a direct connection to cloud servers. This kit enables a wide diversity of applications by exploiting low power communication, multiway sensing and Arm Cortex -M4 core-based STM32L4 series features. The support for Arduino Uno V3 and PMOD connectivity provides unlimited expansion capabilities with a large choice of specialized add-on boards.
