STM32 Discovery Kit STMicroelectronics STM32F746G-DISCO

Part NumberSTM32F746G-DISCO

The STM32F746G-DISCO discovery board (32F746GDISCOVERY) is a complete demonstration and development platform for STMicroelectronics ARM Cortex-M7 core-based STM32F746NGH6 microcontroller.


China PCB Prototype and Fabrication Manufacturer

Detailed Description

This microcontroller features four I2Cs, six SPIs with three multiplexed simplex I2S, SDMMC, four USARTs, four UARTs, two CANs, three 12-bit ADCs, two 12-bit DACs, two SAIs, 8- to 14-bit digital camera module interface, internal 320+16+4 KB SRAM and 1 MB Flash memory, USB HS OTG, USB FS OTG, Ethernet MAC, FMC interface, Quad-SPI interface, SWD debugging support. This discovery board offers everything required for users to get started quickly and develop applications easily.

The full range of hardware features on the board helps to evaluate almost all peripherals (USB OTG HS, USB OTG FS, Ethernet 10/100Mb, MicroSD Card, USART, SAI Audio DAC stereo with audio jack input and output, MEMS digital microphones, SDRAM, Quad-SPI Flash memory, 4.3-inch color LCD-TFT with a capacitive multi-touch panel, SPDIF RCA input, etc.) and develop your own applications. Arduino Uno V3 connectors make it possible to easily connect extension shields or a daughterboard for your specific application. The integrated ST-LINK/V2-1 provides an embedded in-circuit debugger and programmer for the STM32 MCU.

The STM32F746G-DISCO board comes with the STM32 comprehensive software HAL library together with various packaged software examples, as well as a direct access to mbed online resources.
