Can anyone here sincerely verify my schematic and let me know whether it'll work or not?

Hi,

I'm mounting STM32L476RGT6U on PCB. For that, I have made this schematic. I need some expert suggestions from anyone who has in-depth knowledge of this. I'll use an ST-LINK V2 to debug and upload the program to the MCU on PCB.

Have you mounted STM32L476 on PCB? Can you please provide your schematic for STM32L476 so that I can compare and modify mine as per my requirement?

If I need can I order from you?

We used these ST boards before making our own board

STM32L476G-EVAL (expensive)
STM32L496G-DISCO
You can load STM32L476 code onto either of these

Attached example schematic (pdf and DipTrace files)

L476_baseV00PR_DipTrace.zip
Proprietary circuits removed
STLinkV2 with UART (14pin)
Option: USB-C VCP
Option: DAC for real time diagnostics and
Option: Replace DCDC circuit with lower cost option if lower source voltage VH.
Option: LEDs and switches powered from 3V3, change resistors appropriately, careful of required voltage for selected LEDs, as indicators 0.1mA is often plenty.
RGB LED - Careful: Orientation mark is Pin4 Anode, not pin1. Ensure properly instruct solderer or factory, or delete it.
