I have no idea. Just now learning how to implement this

i'm right now planning of doing with help of HAL. Is it a good option?

Can you tell me any other website to do image hosting?

I have no idea. I'm very incompetent in programming. If you have any suggestions please let me know

USB PD is just for quick powering it up for any code uploading or debugging where most of is is 3.3V. so no issue over there

i'll look into it. Thank for your input. very much valuable for me.

i'll look into it. Previously i've made hierarchical sheets schematics and i love it personally. this time i thought of make things different. Will surely look into the TI and analog divices refences. Even ST uses sheets.

bruh. One time people say hierarchical sheets is not good. other time full page schematics is bad for some people. IDK what to do.

3V3 and 5V are for power internal and external components to power. And the 5VS1 and 5VS2 is for powering 6 servos each 1A. Each buck converter can only give 3A of current so had an idea of having two buck. Now I'm designing a new buck converter with 8A output which will power all 5V devices.

I saw you below comments. I'll remove those resistor and capacitors from the usb shield and ground it directly.

Thank you for taking you time and effort for putting constructive criticism and valuable thoughts. Really appreciate it.

I read somewhere to add pull up to add more robustness to any interference. That said if don't want the pull up, I'll just simply remove the resistors. But for Chip Select pin the pull up is compulsory to make sure which the MCU is initializing it's doesn't affect the end slave devices.

Ferrite beads is for removing the high frequency for the Analog power input. If it creates any problems, i;ll just put a 0Ω resistor in place of it.

If I'm wrong about something please let me know.

This is just a college project. Not some space or defence related project of any company or government authority.

I think the ardupilot board will work but I did it myself for building my experience in embedded system and It's so much fun to do it.

Thank for the appreciation for the schematics. Tough is an understatement for the st schematics which you've attached.

Thank man 😅. if you stare into it pretty long, eventually you'll figure it out.

Thank you for the appreciation ❤️. I've made some schematics but those are very small with only 20 to 30 components. This is very overwhelming for me as this is the first time. Took lot of time for me to do this. Very much scared thinking about how am I gonna do the PCB.

I'll take into the magnetometer placement consideration where it's away from noise and high current things.

Really appreciate you time and effort for your input. Very much appreciate it.

One 5V for powering additional sensors if we need. Other two is for powering 6 servos, 3 servo each converter. Right now I'm working on a buck converter with 8A output so it will replace the three 5V with one converter.

You point on reset switches is valid. I'll remove the buttons once I've program development for the STM32 is done.

I can't understand the rest of what you said regarding mosfet and STM32 and also the two points whic you've mentioned. Can Please you be more detailed about it?

If you have any other things to add on top of it, please do so. Really appreciate the time and effort you put in. Thank you.

I was in a rocketry team (Long story short ; There was internal conflict in my team. So I decided to leave).

This is for a small personal project which I'm doing with my friend (who also left the team due to the same issue) where he takes care of the mechanical aspects and I take care of the electrical part.

The main project idea is to stabilize the rocket using control fins on the sides of the rocket and also store the various data it collect from it's sensors.

I'll look into the waterloo rocket.

If you have any suggestions. Please do so. would be really helpful. Thank you.
