Cloud - JAM L4

This is the Cloud application board of JAM family and then is capable of connecting the motion & environmental sensors to the cloud throught Wi-Fi network using SSID, Password and web authentication stored in the dynamic NFC.

JAM is a family of boards that embeds the most used STM32 Nucleo functional packs. Develop with STM32ODE environment, test with STM32-Nucleo and start immediately with Cloud-JAM L4. No firmware or software development needed, simple use the .bin file created for the Nucleo. STM32-Nucleo FW plug & play on Cloud-JAM L4
