Description
The STM32F4DISCOVERY Discovery kit leverages the capabilities of the
STM32F407 high-performance microcontrollers, to allow users to develop audio
applications easily. It includes an ST-LINK/V2-A embedded debug tool, one MEMS
digital accelerometer, one digital microphone, one audio DAC with integrated class D
speaker driver, LEDs, push buttons, and a USB OTG Micro-AB connector.
Specialized add-on boards can be connected by means of the extension header
connectors.

Ordering information
1 Ordering information
To order the STM32F4DISCOVERY Discovery kit, refer to Table 1. For a detailed description, refer to its user
manual on the product web page. Additional information is available from the datasheet and reference manual of
the target microcontroller.
Table 1. List of available products
Order code Board reference User manual Target STM32
STM32F407G-DISC1(1) MB997 UM1472 STM32F407VGT6
1. STM32F407G-DISC1 with ST-LINK/V2-A replaces the obsolete STM32F4DISCOVERY order code with ST-LINK/V2.
1.1 Product marking
The product and each board composing the product are identified with one or several stickers. The stickers,
located on the top or bottom side of each PCB, provide product information:
• Main board featuring the target device: product order code, product identification, serial number, and board reference
with revision.
Single-sticker example:
Product order code
Product identification
DT73589V1
syywwxxxxx
MBxxxx-Variant-yzz
Dual-sticker example:
Product order code MBxxxx-Variant-yzz
and
Product identification syywwxxxxx
• Other boards if any: board reference with revision and serial number.
Examples:
MBxxxx-Variant-yzz
DT76507V1
DT76508V1
or or or
syywwxxxxx syywwxxxxx
MBxxxx-Variant-yzz
On the main board sticker, the first line provides the product order code, and the second line the product
identification.
On all board stickers, the line formatted as “MBxxxx-Variant-yzz” shows the board reference “MBxxxx”, the
mounting variant “Variant” when several exist (optional), the PCB revision “y”, and the assembly revision “zz”, for
example B01. The other line shows the board serial number used for traceability.
Products and parts labeled as “ES” or “E” are not yet qualified or feature devices that are not yet qualified.
STMicroelectronics disclaims any responsibility for consequences arising from their use. Under no circumstances
will STMicroelectronics be liable for the customer's use of these engineering samples. Before deciding to use
these engineering samples for qualification activities, contact STMicroelectronics' quality department.
“ES” or “E” marking examples of location:
• On the targeted STM32 that is soldered on the board (for an illustration of STM32 marking, refer to the
STM32 datasheet Package information paragraph at the www.st.com website).
• Next to the ordering part number of the evaluation tool that is stuck, or silk-screen printed on the board.
Some boards feature 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.
To use the same commercial stack in their applications, the developers might need to purchase a part number
specific to this stack/library. The price of those part numbers includes the stack/library royalties.
