How to connect a STM32F4xxxRE on a custom PCB

[Paulo971]

Hello,

This is the first time I've designed a PCB with a stm32. I found a PDF on the internet that gives me an example of a Nucleo connection but I'm not sure if my schematic is correct.
I don't need all the headerts or the usb connection (I'll be using Stlink v2).
Here's a screenshot of my MCU schematic and my power supply schematic.

 

Can anyone tell me if this is correct or if I need to add or remove components and where?

 

Best regard.

Add capacitor at VCAP1 (AFAIK 2u2, but consult with datasheet).
Bring required level to boot pin.
Connect power supply to AVDD.
Do not connect 11.1V to VBAT pin on MCU !

Single VCAP pin, typically 4u7 F, two pins 2u2 F on each

Pull Down in BOOT0 to ensure your code in FLASH starts, perhaps option to go HIGH if you need to start the ROM based System Loader

Thank you very much, i'll fixe that ASAP.

As far as the stlink connection is concerned, everything's fine?

May want to connect VAPP, it's the MCU generated VDD to tell the ST-Link what signal level to use for the programming pins.

Looks OK.
BTW: STM have appnote about this:
