STMicroelectronics Discovery MCU Development Kit STM32F769I-DISCO

Discovery Kit for STM32F769NI Microcontroller

From STMicroelectronics, STM32F769I-DISCX Discovery kits feature a STM32F769NIH6 microcontroller based on the ARM Cortex-M7 32-bit core. STM32F769 Discovery kits provide you with the quickest way to evaluate the STM32F7 series. These discovery kits feature Arduino connectivity that enables you to use an extensive range of specialised add-on boards whilst offering an unlimited range of expansion capabilities.

STM32F769I-DISCX Discovery kits feature a number of integrated accessories (such as a B-LCDAD-RPI1 printed circuit DSI adapter board). These accessories give you greater flexibility and allow the kit to be used for a wider range of applications. An integrated B-LCDAD-HDMI1 DSI to HMDI adapter allows you to easily connect and display outputs via HDMI onto enabled displays.

STM32F769I-DISCX Discovery kits are supplied with comprehensive free firmware that is part of the STM32CubeF7 package. The kits are well suited to embedded applications and are supported by integrated development environments. Open source software can also be used.

Applications:

These discovery kits can be used in a wide range of projects as they feature multi-sensor support, audio, video, graphics and high-speed connectivity with a large set of communication peripherals. They are highly responsive which makes them ideal to support IoT applications such as smart thermostats, fitness devices, smart device interfaces (such as washing machines), waveform generators and paper cutters. STM32F769I-DISCX kits can also be controlled remotely using a VNC client.

STM32F769I-DISCX Discovery kits have 2 audio PLLs, 3 half-duplex I2S interfaces, a serial audio interface that supports time-division multiplex mode and a digital filter for a sigma-delta modulator (DFSDM). This gives you video player functionality. STM32F769I-DISCX kits can be used as part of an alarm system, controlling cameras within a building and monitoring different zones autonomously. Micro SD cards and USB keys can be used to expand the memory.

Other applications include home automation, industrial and medical applications.
