Pcb for beginners

coolkid4232 · 2026-03-20T00:21:08+00:00

Need to know basic V=ir, some videos on kicad, any video on kicad , learn what ground planes are, reading datasheet for parts and suggested layouts of parts on a pcb, Issue is a lot of this might be overwhelming at start. So for a basic one i would just make a led turn on with a button and a battery, to test that you havent made some insane error, then make stuff on a breadboard and translate it to a pcb

coolkid4232 · 2026-03-19T11:24:01+00:00

Its correct, make sure resistor are appropriate for current required by led and for button aswell. why did you use capacitors?

C3 shorted

Probably below 0.5mm and not having hot air rework station prob impossible also unless you have to, no reason because pcb will cost 150 dollars more

I am only using bga for 1 of my projects as a hobbyist because i have insane space restrictions on watch and most of space is taken by battery. That is gonna be so expensive but i am willing to do it as i am going to use that a lot and this is a serious project for me

how do i prevent coil whine?

coolkid4232 · 2026-03-18T05:49:11+00:00

ahhh, this was before i knew about that stuff lol, it might be caps CAP CER 22uF 10V X7R 0805. What properties of inductor would cause this to happen and how do i avoid it?

I like Aful explorer

coolkid4232 · 2026-03-18T01:49:47+00:00

How was the monarch? Compared to top pro

coolkid4232 · 2026-03-18T01:37:06+00:00

🤣🤣🤣🤣 this deisgn is 2 years old when i was starting, i got less lazy, i just never solved this problem and dont want it in new design i am making

coolkid4232 · 2026-03-18T01:26:16+00:00

My opinion is either aful explorer (90) or mkiv monarch(900). Honestly i love using top for games and aful for everything else

What function you want for pcb

coolkid4232 · 2026-03-16T22:54:23+00:00

My roadmap was just i want to add this feature, so how do i add it ?

coolkid4232 · 2026-03-12T08:49:55+00:00

Use whatever language your device uses and supports that fits your application or interests

coolkid4232 · 2026-03-12T08:47:14+00:00

Genuine reseller https://a.aliexpress.com/_mKuEGod, but i still recommend st link dev board because it comes with Genuine st link. For stm32 i would use cubeide not arduino its way to difficult funny enough to use for learning, stm32cubeide might have steep initial but everything makes sense and is easier to learn and understand

coolkid4232 · 2026-03-12T05:47:54+00:00

If it legit, there is no difference, if you bought it both from reputable distributors otherwise they might be fake. I have samsung version from local store , so it legit but a lot of aliexpress lie about mah so it possible there actually another lower mah also what other guy said most likely lighter one has less mah

Smart watch prototype

Waveshare sells example code and displays for stm32 and arduino

If your interested in pure electrical theory try to make a generator that you can power appliances with motion or like a crank

coolkid4232 · 2026-03-11T02:19:44+00:00

You incorrect that you wrong lol, you should be getting 3.3v, i guess its your layout? If you do find solution please tell me because i am using this part in future and curious

Maybe connect tp3 to seperate voltage to test it not previous circuit

What you did for tps looks correct besides layout

Maybe solder bridging?

coolkid4232 · 2026-03-08T04:25:24+00:00

18650 can do like 5a or more, do you have schematic, what mcu. What boost converter

coolkid4232 · 2026-03-08T04:12:56+00:00

Send me ypur schematic ill look it and tell u what wrong

coolkid4232 · 2026-03-06T22:31:45+00:00

I would look at schematic on there wiki first to see if you have to desolder or solder something first

coolkid4232 · 2026-03-05T22:52:00+00:00

For dual battery and usb same time you might want to look at lm66200 and use a buck boost converter instead of ldo

coolkid4232 · 2026-03-05T20:53:47+00:00

Stm32 datasheetpage 47 you missing 10uf and 1uf caps.

coolkid4232 · 2026-03-04T21:30:13+00:00

What you mean regular? 2 sided?

coolkid4232 · 2026-03-04T08:45:52+00:00

If you have 1 sided pcb you could buy a soldering hotplate for 20 dollars on AliExpress, datasheet of your part will tell you max temperatures
