STMicroelectronics Discovery Node A2 STM32L475VG Bluetooth Smart (BLE), Near Field Communication (NFC), RF Transceiver,

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.
