Hardware Design with the RP2040: Custom PCB Based on the Raspberry Pi Pico | Digi-Key Electronics

Could someone tell me What is the point of the pico firmware while the code is already running perfectly?

Just imagine me firing a gas oven at home to solder a bunch of modchips :D

One day I hear the oven door slam closed, my damn housemate went to "check" what I was doing... smashed everything off the boards, my entire day wasted :(

This video is so very important for anyone just starting out on developing custom RP projects. Thank you thank you !

Thanks for a really excellent video that shows the kinds of practical considerations and troubleshooting involved when going from a design concept to component selection, schematic, board layout, pcb fabbing, parts sourcing, populating the board, soldering, board re-work, and functional testing. You cover a ton of ground in under an hour. I've done lots of similar prototyping work, but not as neatly and nicely as you, and it's always great to see how other people approach the same problems. I also learned I've been pronouncing KiCad wrong. Great work.

Coming from China, I own RP2040 Raspberry PI chip

Helpful video, thanks!

Can you please tell me what kind of flux you use? It is so much cleaner than mine! lol

Thaaaaannnnnks yuuuuuuu i always get a vid on what I want from shawn😚

Awesome video!

Hey Question W25Q16 any of them will be compatible?

super nice!! I have learned a lot from your video ,thank you very much!

Not sure why you decided to rework the chip instead of just soaking away solder bridges with a clean iron tip as you did after,
but your flux evaporated by the time you pre-heated PCB with hot air gun.
Instead look for good gel flux. It won't boil, evaporate immediately and should only liquify at a considerable temp.

Really helpful video!
I have a doubt after making custom pcb using rp2040 where we use that new ldo we don't need gpio pin 23
So can we use it freely ?
Same for gpio pin 24
Or will Pico sdk interfere

To reset the board we can have switch on the RUN pin but in your schematic your have given +3.3v with 10K resistor. Does this needed because in datasheet in was not mention.

Great Video!

One question, what do you have to do if you want to make PCBs and built versions available for sale, FCC, CE,

etc.? For Hobby and general prototyping use? It looks like no one talks about this.

Arggh! "C"!?!

Woah, kicad really looks old and white without an OS to provide a proper GTK theme.

first of all great video. inspired from this i also made my PCB. during testing i encounters problem . instead of W25q16 i used W25q08 which is half the size.
my problem is i can recognise it in drive on boot mode and successfully able to put uf2 file. but when i connect it to thonny in programming mode it's not recognised.

i tryied plugin plugout, restart thony, restart computer.
Std pi Pico is working without problem.

need your help

sir can i use other flash chip? W25Q128 or W25Q32 chip? Please reply

Loving the RP2040 so far. Somebody needs to just sell a debugger for Pico. Its cool you can use another Pico as a debugger but as you say it takes up space and in my experience Pico probe actually working is super glitchy and depends highly on how good the wire connections are between the 2.

Excellent lecture, thank you very much, see you next time

Excellent video, many thanks.
I have found that for hand-soldering one could benefit by having larger pads for the 5-pin v-reg part.

Crazy.... DIP socket pins were close enough for me. This is definitely something for younger eyes.

We have designed custom rp2040 board. But we are facing issue of continue mount even we didn't press bootsel button. What could be the possible issue , anyone help on this.

When you rework and use the iron for wicking the small round tip is not desirable. You can use a bit of solder wick and a flat blade type iron. Using a temp controlled iron is recommended. The flat blade will act like a wick and pull the solder to it. Also when using a blade tip you place it near the edges of the pins and then pull away. What you are doing is moving the solder to the next pin and that could create a bridge where you did not have one. I used to work as a tech and have done lots of rework. I have used solder wicking braid to aid in exess solder removal. You just have to use it on the edge of the pins and not on top or too close to the chip. 3 second rule applies as well.

Can we use ftdi ft232rl to program rp2040

nice

Not sure I share your apprehension about 0402s. I've never had any issue soldering them, though I do use a microscope.

The biggest problem I've had, is that the tiniest twitch on my tweezers, or static, will send them flying across the room ... never to be seen again. At least they're cheap. Other considerations: They have no markings, so it's easy to get them mixed up. And they're too small to put traces between the pads.

Thank you Shawn ;-) It's VERY REFRESHING to see someone who's willing to go beyond blinking F$%#!ing LEDs. Much appreciated.

hello, I would like to ask, if you burn bootloader on rp2040? I would like to make own pcb and pay for assembly rp2040 manufacturer, but probably it will be not easy to run rp2040 just by copy firmware

thanks, very helpfull!

الف شاكرا لك سعيده بقراءة الواضحه امنت وجعلها الله حقيقه وظهر الحق ومات الباطل ان شاء الله

Thanks great video

Go pico yeah yeah go pico yeah

Excellent video! Really, really helpful to understand how this all works and to see that it's not THAT scary to make your own PCB.

Thank you Shawn!

Nice Video Shawn.
I think you have to go to make some DIY projects videos like your reflow Oven :)

How's KiCad compared to the old Altium?
Being open source usually means it's buggy.
I just learned that you can't run and Auto-update Kicad from within KiCad!
That's not a good sign!

Good content as usual. I learned KiCad from your excellent tutorials. Thank you Shawn. Cheers.
