+This directory contains examples for the _original_ stm32f4 discovery.
+The PCB should be labelled either MB997A or MB997B, and contains a user USB
+port, and an audio dac on board, along with a MEMs microphone and an
+accelerometer.

+The later stm32f4 discovery boards, for the f401, MB91115B and for the f429i,
+MB1075B will not work as is with these demos, but they should only need minor
+tweaking for pin configurations.
