2 Ordering information
To order the 32F469IDISCOVERY Discovery kit, refer to Table 1. Additional information is
available from the datasheet and reference manual of the target microcontroller.
Order code Board reference Target STM32

2.1 Product marking
Evaluation tools marked as "ES" or "E" are not yet qualified and therefore they are not ready
to be used as reference design or in production. Any consequences deriving from such
usage will not be at ST charge. In no event, ST will be liable for any customer usage of
these engineering sample tools as reference design or in production.
"E" or "ES" marking examples of location:
• On the targeted STM32 that is soldered on the board (for illustration of STM32 marking,
refer to the section “Package information” of the STM32 datasheet available at
www.st.com).
• Next to the evaluation tool ordering part number, that is stuck or silk-screen printed on
the board.
Table 1. List of available products
This board features a specific STM32 device version, which allows the operation of any
bundled commercial stack/library available. This STM32 device shows a "U" marking option
at the end of the standard part number and is not available for sales.
In order to use the same commercial stack in his application, a developer may need to
purchase a part number specific to this stack/library. The price of those part numbers
includes the stack/library royalties.
