STM32F407 Discovery Kit

The STM32F407 Discovery 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 the integrated class D speaker driver, LEDs, push-buttons, and a USB OTG micro-AB connector.
To expand the functionality of the STM32F4 DISCOVERY 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 STM32F4 DISCOVERY.
