STMicroelectronics – MCU board provides microphones and display for developing audio and video applications


The 32F413HDISCOVERY kit from STMicroelectronics allows users to develop applications based on an STM32F4 microcontroller, which features the ARM® Cortex®-M4 processor core.

At the heart of the 32F413HDISCOVERY kit is a STM32F413ZHT6 MCU, which has 1.5Mbytes of Flash memory and 320kbytes of SRAM and is housed in a 144-lead QFP package.

Like all the STM32F4 series MCUs, the STM32F413ZHT6 is well equipped with audio, sensor interface, graphics, security and video functions and high-speed connectivity. It has an LCD parallel interface, two 12-bit DACs, a 12-bit ADC, 12 Pulse-Density Modulation (PDM) interfaces, one serial audio interface, up to five I2S interfaces, and a USB2.0 controller with PHY.

The 32F413HDISCOVERY kit provides support for ArduinoTM Uno V3 connectivity, giving unlimited expansion capabilities from a wide choice of add-on boards.

The kit supports ARM’s Keil® development toolchain, as well as IAR and Atollic tools and the ARM mbedTM platform.
