PCB Review Request, a chud beginner's first one

Hey guys, first time doing a PCB which isn't just an led and coin battery. This is a STM based telemetry project, with pinholes for an mcu6050 connect, an OLED, pins for programming the STM32f446re, and pins so I can cable out a hall effect monitor. Was wondering if I could get a review over, I didn't have much guidance on the PCB routing part, but I did have a base project which I copied from a friend's schematic for the regulator part of the schematic.

I'd appreciate all the help I can get, and I'm open to any critique.

Chud beginner wondering what's needed to make PCB with standalone chip and not Nucleo carrier

Hey guys, I've finished my prototype of a project (thank you claude code) for a simple telemetry system, and now I am moving on to the PCB prototyping. I'm using a Nucleo board for F446RE for development, but I dont want my board to just be a nucleo carrier, and I'm gonna design it with the chip by itself and build the other things up.

With that, I'm still confused on all the thing's ill have to add to make that chip work alone, and specifically finding a datasheet which points me in the right direction .

I know I need a few things connected

  1. Oscillator crystal
  2. FRAM
  3. Power filtering for microcontroller
  4. STM32 Prog/Debug
  5. Power regulators (i hvae a 12v DC input, so some bucks to step down to +5v and +3.3v respecitvely.

Is there anything else I need? And i can't find a datasheet showing PCB setup, but i found one like 1300 pages long explaining all the registers and stuff. The photo I have is something I got from copying a similar project which im kind of basing mine off of but i need to go past it.

Chud beginner can’t figure out st link device error

Hey guys completely new to STM and I bought an F446RE development board to practice and teach myself.

Just doing basic things like trying to get the onboard LED to blink but it won’t work because I just keep getting this recurring error where it can’t initialize the st link device.

Any idea why this is? I know it’s probably something basic I’m missing but I straight up idk

Is the semiconductor field over saturated or a good prospect.

Hey guys. Senior in highschool going to study ECE at a T10 university in America this fall and I think I want to go into semiconductor field/computer architecture. I’m not sure what part yet as it’s incredibly broad, and there’s design snd VLSI, or the physics side, or manufacturing, or RF.

I see so many posts about people getting one job off of 200 applications, and how the computer engineering field is super cutthroat right now, so I’m wondering if I am making a mistake joining this field right now (I don’t want to have the job market of a CS major).

Chips in America are on the up and up though, so maybe there is hope?
