3 Quick start
AT-START-F403 is a low-cost and easy-to-use development kit that is designed for quick
evaluating and using the high-performance AT32F403 microcontrollers to develop applications.
3.1 Get started
Configure the AT-START-F403 board in the following order to start the application:
1. Check the Jumper position on the board:
JP1 is connected to GND or OFF (BOOT0 is 0, and BOOT0 has an pull-down resistor in the
AT32F403ZGT6);
JP4 optional or OFF (BOOT1 is in any state);
JP8 one-piece jumper is connected to the USB on the right.
2. Connect the AT-START-F403 board to the PC through a USB cable (Type A to micro-B), and
the board will be powered via AT-Link-EZ USB connector CN6. LED1 (red) is always on, and
other three LEDs (LED2 to LED4) start to blink in turn.
3. After pressing the user button (B2), the blinking frequency of three LEDs are changed.

4.1 Programming and debugging
4.1.1 Embedded AT-Link-EZ
The evaluation board embeds Artery AT-Link-EZ programming and debugging tool for users to
program/debug the AT32F403ZGT6 on the AT-START-F403 board. AT-Link-EZ supports SWD
interface mode and a set of virtual COM port (VCP) to be connected to the
USART1_TX/USART1_RX (PA9/PA10) of AT32F403ZGT6. In this case, PA9 and PA10 of
AT32F403ZGT6 will be affected by AT-Link-EZ as follows:
PA9 is weakly pulled up to high level by the VCP RX pin of AT-Link-EZ;
PA10 is strongly pulled up to high level by the VCP TX pin of AT-Link-EZ
The user can set R16 and R24 OFF, then the use of PA9 and PA10 of AT32F403ZGT6 is not
subject to the above restrictions.
Please refer to AT-Link User Manual for complete details on the operations, firmware upgrade and
precautions of AT-Link-EZ.
The AT-Link-EZ PCB on the evaluation board can be separated from AT-START-F403 by bending
over along the joint. In this case, AT-START-F403 can still be connected the CN7 of AT-Link-EZ
through CN2 (not mounted before shipping), or can be connected with another AT-Link to continue
the programming and debugging on the AT32F403ZGT6.
4.1.2 20-pin ARM® standardJTAG connector
AT-START-F403 also reserves JTAG or SWD general-purpose connectors as
programming/debugging tool. If the user want to use this interface to program and debug the
AT32F403ZGT6, please seperate the AT-Link-EZ from the board or set R41, R44 and R46 OFF,
and connect the CN3 (not mounted before shipping) to the programming and debugging tool.
4.2 Power supply selection
The 5 V power supply of AT-START-F403 can be provided throug a USB cable (either through the
USB connector CN6 on the AT-Link-EZ or USB connector CN1 on the AT-START-F403), or
through an external 5 V power supply (E5V), or by an external 7~12 V power supply (VIN) via 5V
voltage regulator (U1) on the board. In this case, the 5 V power supply provides the 3.3 V power
required by the microcontrollers and peripherals by means of the 3.3 V voltage regulator (U2) on
the board.
The 5 V pin of J4 or J7 can also be used as an input power source. The AT-START-F403 board
must be powered by a 5 V power supply unit.
The 3.3 V pin of J4 or the VDD pin of J1 and J2 can also be directly used as 3.3 V input power
supply. AT-START-F403 board must be powered by a 3.3 V power supply unit.
Note: Unless 5 V is provided through the USB connector (CN6) on the AT-Link-EZ, the AT-Link-EZ will
not be powered by other power supply methods.
When another application board is connected to J4, the VIN, 5 V and 3.3 V pins can be used as
output power; the 5 V pin of J7 used as 5 V output power; the VDD pin of J1 and J2 used as 3.3 V
output power.
