2 Quick start

The STM32F030 Value Line Discovery kit is a low-cost and easy-to-use development kit to

quickly evaluate and start development with an STM32 F0 series microcontroller.

Before installing and using the product, please accept the Evaluation Product License

Agreement from www.st.com/stm32f0-discovery.

For more information on the STM32F030 Value Line Discovery kit and for demonstration

software, visit www.st.com/stm32f0-discovery.

2.1 Getting started

Follow the sequence below to configure the STM32F030 Value Line Discovery kit and

launch the DISCOVER application:

1. Check jumper position on the board, JP2 on, CN2 on (Discovery selected).

2. Connect the 32F0308DISCOVERY board to a PC with a USB cable ‘type A to mini-B’

through USB connector CN1 to power the board. Red LED LD1 (PWR) and LD2 (COM)

light up and green LED LD3 blinks.

3. Press user button B1 (bottom left corner of the board).

4. Observe how the green LED LD3 blinking changes according to USER button B1

clicks.

5. Each click on USER button B1 is confirmed by the blue LED LD4.

6. To study or modify the DISCOVER project related to this demo, visit

www.st.com/stm32f0-discovery and follow the tutorial.

7. Discover the STM32F0 features, download and execute programs proposed in the list

of projects.

8. Develop your own application using available examples.

UM1658 Features

3 Features

The STM32F030 Value Line Discovery kit offers the following features:

•STM32F030R8T6 microcontroller featuring 64 KB Flash, 8 KB RAM in an LQFP64

package

•On-board ST-LINK/V2 with selection mode switch to use the kit as a standalone

ST-LINK/V2 (with SWD connector for programming and debugging)

•Board power supply: through USB bus or from an external 5 V supply voltage

•External application power supply: 3 V and 5 V

•Four LEDs:

– LD1 (red) for 3.3 V power on

– LD2 (red/green) for USB communication

– LD3 (green) for PC9 output

– LD4 (blue) for PC8 output

•Two push buttons (user and reset)

•Extension header for LQFP64 I/Os for quick connection to prototyping board and easy

probing.

•An additional board is provided with the kit which can be connected to the extension

connector for even easier prototyping and probing.

•A large number of free ready-to-run application firmware examples are available on

www.st.com/stm32f0-discovery to support quick evaluation and development.
