Description
The Discovery kit for STM32F334 line helps you
to discover the digital power features of the
STM32F334 line microcontrollers and to develop
your applications easily. It offers everything
required for both beginners and experienced
users to get started quickly.
Based on an STM32F334C8T6, it includes an STLINK/V2-1 embedded debug tool interface, high
brightness LED dimming with buck converter,
buck/boost converter, LEDs and pushbuttons.

Features
• STM32F334C8T6 microcontroller featuring 64
KB of Flash memory, 16 KB RAM in an
LQFP48 package.
• On-board ST-LINK/V2-1 with selection mode
switch to use the kit as a standalone STLINK/V2-1 (with SWD connector for
programming and debugging).
• mbed™-enabled (mbed.org)
• USB ST-LINK with re-enumeration capability
and three different interfaces:
– virtual com port
– mass storage
– debug port
• Board power supply: through USB bus or from
an external 5 V supply voltage.
• External application power supply: 3 V and 5 V.
• High brightness LED dimming with buck
converter.
• One buck / boost converter.
• Six LEDs:
– LD1 (red) for 3.3 V power on
– LD2 (red/green) for USB communication
– Four user LEDs: LD3 (red), LD4 (orange),
LD5 (green) and LD6 (blue).
• Two pushbuttons (user and reset).
• Extension header for LQFP48 I/Os for a quick
connection to the prototyping board and easy
probing.
• Comprehensive free software including a
variety of examples, part of STM32CubeF3
package or STSW-STM32148 for legacy
Standard Library usage.
