The STM32F4DISCOVERY kit leverages the capabilities of the STM32F407 high performance microcontrollers, to allow users to easily develop applications featuring audio.

It includes an ST-LINK embedded debug tool, one ST-MEMS digital accelerometer, a digital microphone, one audio DAC with integrated class D speaker driver, LEDs, push-buttons and an USB OTG micro-AB connector.

To expand the functionality of the STM32F4DISCOVERY kit with ethernet connectivity, LCD display and more, visit the www.st.com/stm32f4dis-expansion webpage.

With the latest board enhancement, the new order code STM32F407G-DISC1 has replaced the old reference STM32F4DISCOVERY.
