Description
The 32F3348DISCOVERY Discovery kit for the STM32F334 line is based on an
STM32F334C8T6 microcontroller. It highlights the digital power features of the
STM32F334 line microcontrollers. The Discovery kit for the STM32F334 line makes it
possible to develop applications easily, and it offers everything required for both
beginners and experienced users to get started quickly.
The Discovery kit for the STM32F334 line includes an ST-LINK/V2-1 embedded
debug tool interface, buck/boost converter, high brightness LED dimming with buck
converter, LEDs, and push-buttons.

1 Ordering information
To order the 32F3348DISCOVERY Discovery kit, refer to Table 1. For a detailed description of each board, refer
to its user manual on the product web page. Additional information is available from the datasheet and reference
manual of the target STM32.

1.1 Product marking
The stickers located on the top or bottom side of all PCBs provide product information:
• First sticker: product order code and product identification, generally placed on the main board featuring
the target device.
Example:
Product order code
Product identification
• Second sticker: board reference with revision and serial number, available on each PCB.
Example:
MBxxxx-Variant-yzz
syywwxxxxx
On the first sticker, the first line provides the product order code, and the second line the product identification.
On the second sticker, the first line has the following format: “MBxxxx-Variant-yzz”, where “MBxxxx” is the board
reference, “Variant” (optional) identifies the mounting variant when several exist, “y” is the PCB revision, and “zz”
is the assembly revision, for example B01. The second line shows the board serial number used for traceability.
Parts marked as “ES” or “E” are not yet qualified and therefore not approved for use in production. ST is not
responsible for any consequences resulting from such use. In no event will ST be liable for the customer using
any of these engineering samples in production. ST’s Quality department must be contacted prior to any decision
to use these engineering samples to run a qualification activity.
“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 evaluation tool ordering part number 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.
