STM32429I-EVAL evaluation board for STM32F429 MCUs
Introduction
The STM32429I-EVAL evaluation board is a complete demonstration and development
platform for STMicroelectronics Arm®Cortex®-M4 core-based STM32F429NIH6
microcontrollers. It features three I2C, six SPI with two muxed full-duplex I2S, SDIO, four
USART, four UART, two CAN, three 12-bit ADC, two 12-bit DAC, one SAI, 8- to 14-bit digital
camera module interface, internal 256+4 Kbyte SRAM and 2-Mbyte Flash memory, USB HS
OTG and USB FS OTG, Ethernet MAC, FMC interface, JTAG debugging support. This
evaluation board can be used as a reference design for user application development but it
is not considered as a final application.
The full range of hardware features on the board helps the user to evaluate all peripherals
(such as USB OTG HS, USB OTG FS, Ethernet, motor control, CAN, microSD™ card,
USART, Audio DAC and ADC, digital microphone, IrDA, CAN, RF-EEPROM, SRAM, NOR
Flash memory, SDRAM, 4.3" TFT LCD with a resistive touch panel, and others) and develop
his own applications. Extension headers make it possible to easily connect a daughterboard
for specific applications development.
The integrated ST-LINK/V2 provides an embedded in-circuit debugger and programmer for
the STM32 MCU.

3.3 Demonstration software
Demonstration software is preloaded in the Flash memory of the board for easy
demonstration of the device peripherals in stand-alone mode. For more information and to
download the latest version, refer to the STM32429I-EVAL demonstration software on
www.st.com.
3.4 Delivery recommendations
Some verifications are needed before using the board for the first time to make sure that
nothing was damaged during shipment and that no components are unplugged or lost.
When the board is extracted from its plastic bag, please check that no component remains
in the bag.
The main components to verify are:
1. The 25 MHz crystal (X2) and 25 MHz crystal (X4), which may have been removed by a
shock from their sockets.
2. The microSD™ card, which may have been ejected from the connector CN17 (right
side of the board).
3. The dual-interface EEPROM board, which may have been unplugged from the
connector CN3 (top left corner of the board).
4. The camera module on the camera daughterboard (MB1066), which may have been
unplugged.
Warning: There is a risk of explosion if the battery is replaced by an
incorrect one. Make sure to dispose of used batteries
according to the instructions.

Hardware layout and configuration UM1667
10/59 UM1667 Rev 3
4 Hardware layout and configuration
The STM32429I-EVAL evaluation board is designed around the STM32F429NIH6 (216-pin
TFBGA package).
The hardware block diagram Figure 2 illustrates the connection between the
STM32F429NIH6 and peripherals (SDRAM, SRAM, NOR Flash memory, camera module,
color LCD, USB OTG connectors, motor control connector, USART, IrDA, Ethernet, audio,
CAN, RF-EEPROM, microSD™ card and embedded ST-LINK). Figure 3 helps the user to
locate these features on the actual evaluation board.
