32F3348DISCOVERY

Discovery kit for STM32F334 line

Data brief

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 ST-

LINK/V2-1 (with SWD connector for

programming and debugging).

• 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.
