Hello everyone!
I’m new here, I’m a software engineer but I started to learn more about PCB design and electronics given the fact that I worked with PCB / electronics designers in my previous company.

I designed my FIRST schematics that “apparently” should work. I just want to be able to boot ESP32-S2 MCU and upload a program over the USB (I don’t need SPI, I2C or whatever).

So, please, is there a possibility someone could point me what (and why) is wrong with schematics (both the power supply and MCU design) and also what and how to fix if possible, please?

I also tried to replicate my first power supply (3V3) in Multisim and according to Multisim, it should work. I used LM1117DT and similar Schottky diode in Multisim as there is no AMS1117-3.3 component and no SS14 diode but it should be close to it.



Thank You in advance!
Best regards!

 

The only flaw I can see is that the 0.1 mfd capacitors are not close enough to the voltage regulator IC. The standard recommendation is connected within 0.1 inch. I have no clue how a simulator handles that requirement.
