Discovery Kit for STM32F769NI Microcontroller
The STM32F769I-DISCx Discovery Kits help explore the STM32F7 Series of microcontrollers based on the ARM Cortex-M7 32-bit core. The Discovery kit enables a wide diversity of applications to be realised, taking benefit from audio, multi- sensor support, graphics, security, video and high-speed connectivity features. The Arduino connectivity support provides unlimited expansion capabilities with a large choice of specialised add-on boards. The latest versions of the demonstration source code and associated documentation can be downloaded from the manufacturer webpage. Available with or without a TFT LCD display board.
