			=Supplier=

			THe STM discovery boards look all quite alike. To make sure you get the right board here a direct [[http://nl.farnell.com/stmicroelectronics/stm32f4discovery/stm32f407-usb-otg-discovery-kit/dp/2009276 link at Farnell]]
			Whatever supplier yo choose make sure it is a STM32F407 ,mind the 07 in the end, board.
