Discovery kit with STM32F469NI MCU

Introduction

The STM32F469I-DISCO discovery board (32F469IDISCOVERY) is a complete 
demonstration and development platform for STMicroelectronics ARM

®

 Cortex

® 

-M4 core-

based STM32F469NIH6 microcontroller. This microcontroller features three I

2

C interfaces, 

six SPIs with two multiplexed full-duplex I

2

S interfaces, SDIO, four USARTs, four UARTs, 

two CANs, three 12-bit ADCs, two 12-bit DACs, one SAI, 8 to 14-bit digital camera digital 
module interface, internal 320+4 Kbytes of SRAM and 2-Mbyte Flash memory, USB HS 
OTG and USB FS OTG, Ethernet MAC, FMC interface, MIPI DSI interface, Quad-SPI 
interface, JTAG debugging support. This discovery board offers everything required for 
users to get started quickly and develop applications easily.

The hardware features on the board helps users to evaluate the following peripherals: USB 
OTG FS, microSD card, Audio DAC with headset jack, digital microphones, SDRAM, Quad-
SPI Flash memory, 4" TFT LCD using MIPI DSI interface with capacitive touch panel.The 
Arduino

 compatible connectors expand the functionality with a wide choice of specialized 

shields.The extension header makes it possible to easily connect a daughterboard for 
specific application. The integrated ST-LINK/V2-1 provides an embedded in-circuit 
debugger and programmer for the STM32 MCU.
