10 PC via USB, a driver for ST-LINK/V2-1 must be installed. It can be downloaded from the www.st.com webpage. If the STM32F469I-DISCO board is connected to the PC before installing the driver, the ® Windows device manager may report some USB devices found on STM32F469I-DISCO as “Unknown”. -
Page 13: Power Supply
4.2.2 Supplying the board through ST-LINK/V2-1 USB port To power the STM32F469I-DISCO board in this way, the USB host (a PC) gets connected with the STM32F469I-DISCO board via a USB cable to the ST-LINK/V2-1 connector. In the first step, only the ST-LINK part U3 is powered by the PC. In fact, before USB enumeration, the host PC provides only 100 mA to the board at that time. -
Page 14: Measurement Of Current Idd Drawn By The Stm32F469Ni
The ST890 power switch protects the USB port of the host against current demand exceeding 600 mA, should a short-circuit occur on the board. The STM32F469I-DISCO board can also be supplied from a USB power source not supporting enumeration, such as a USB charger. In this particular case, the solder bridge SB16 must be closed. -
Page 15: Clock Source
The 32.768 kHz crystal X3 is the clock source for the embedded RTC. Reset source The reset signal of STM32F469I-DISCO board is low active and the reset sources include: • Reset button B1, providing solder bridge SB1 is closed (default setting) •... -
Page 16: Audio Outputs
An USB OTG full speed communication is available at connector CN13. The STM32F469I-DISCO Discovery board can be powered by the 5 V DC of this USB OTG FS connection. When the STM32F469I-DISCO is USB host, it supplies the USB peripheral. -

1. Before using pin4 of CN6 as +3.3V input, the solder bridge SB8 must be removed. Otherwise the board STM32F469I-DISCO could be damaged by the over-current. 2. The external voltage applied to pin VIN must be in the range from 6 V to 9 V at 25°C ambient temperature. -
Page 19: Extension Connector Cn12
The extension connector CN12 is a 2.54 mm pitch header located at the bottom side of the STM32F469I-DISCO Discovery board. It is composed of 16 square pins of 0.64 mm arranged in double row and it is compatible with usual connectors mating with 2.54 mm headers, having 0.64 mm square posts. - Page 20 Table 6.
