How to Make Custom ESP32 Board in 3 Hours | Full Tutorial

[@RobertFeranec]

Thank you for watching. PS: Project is here: oshwlab.com/robertferanec/esp32-tutorial

[@EFazy]

Dear Robert! I've just created a 2 layer board in EasyEDA, thanks for this awesome tutorial! I have a question in my mind however... My board is an H-Bridge which will handle 10A current spikes, a few amp countinous current. (I upgrade my kid's electric tractor)... So I just did the layout, and I have some space on the board to route a few tracks on both side a top of each other (for example from the MOSFETs to motor connector) If I do this, should I put VIAs along the way to connect the two sides multiple time, or is just ok if the connection is made in the two ends (THT connector and FET had been used) Thanks, Peter

[@RobertFeranec]

@@EFazy that's super cool. I am very happy this tutorial helped. PCB tracks can withstand high currents (I have some videos about burning PCB tracks) + I discuss high current PCB design with Steve Sandler. I don't know how wide are your tracks, but you can use Saturn PCB calculator (free software) to double check if you would need paralell tracks. 10A is not so much - it may not be necessary, especially if your input - output are on the same side of PCB - in that case most current will probably flow on one side anyway. However, having GND plane on the other side may help with possible EMC / EMI reduction (which may not be relevant in your case). kzbin.info/www/bejne/jZXPf2uYfdxgrZI kzbin.info/www/bejne/qXu0mmysmKiKY6c

[@burakkrkl4689]

The most beautiful saying "PERFECT" I've ever heard in my life ( I will use that voice sample on my home assistant wallpanel if @robertferanec allows it 🙄). Excellent job. I am using these boards in my house automation system without knowing how they work internally. Now I have a good idea of how this kind of system works.

[@Taki7o7]

Why not using USB-C tho? :D Personally hate the boards not coming with USB-C already because the other connectors die even faster :(

[@kennethbeal]

Thank you so much for this! Want to say, @2:52:52 (palindrome :) ), I see you using a web page from DroneBotWorkshop. I've been learning a lot from his videos! That's so cool. Am helping my nephew write video games, and I plan to introduce him to "smaller computers" this Christmas, with displays and PictoBlox which is like MIT's Scratch, which can run on esp32 etc. Thank you again!

Another awesome contribution to the community 👍 , having started doing layout on light tables using vellum and bishop tape all I can say is this generation of engineers have no excuse for producing nothing short of excellent designs . Modern tools and your guidance and generosity of sharing many years of your experience is all they need . Having purchased your Cadence course a few years back it saved me $ 1000’s of dollars of wasted time getting to know the tool chain 🙏👍👏

[@RobertFeranec]

Totally agree. I wish I had the same possibilities when I was a teenager. PS: Thank you very much for buying our courses, you support helps with creating this free content.

[@TYGAMatt]

Inspirational! I'm in process trying to design a PCB for a motorcycle CDI. I was really stuck today but your video has given me a bunch of new ideas and a lot of enthusiasm. Thank you so much for taking the time to do this. Perfect!

[@miguelake288]

Hi Robert, Thank you for the great video! Great content as always I would like to share a little tip: When you are routing a line on the top layer, and you want to pass to the bottom layer through a VIA (e.g., at 01:35:15), you can just switch the layer on the "Layers and objects" box, and it creates the VIA automatically from your current layer to the one to which you changed to (instead of (1) stopping the routing command, (2) placing the VIA, (3) switching the layer, and (4) starting the routing command again).

[@ratbagley]

I was just thinking that. Little tricks....

[@D-Khaz]

Great video! Only wish that you went a bit more into explaining why you physically placed the components where you did on the PCB. It might be that you had already designed one of these and was copying it, but it would still be good to understand the logic when you’re initially laying things out.

[@rohandesigns]

Thanks for the great tutorial, Robert! At first I was a little discouraged by the 3 hours, but it is by far the best tutorial I have seen so far on this subject. And now I discovered others of your quality videos, 8-9 hours in total. :)

I am just getting into designing my own PCB's and this is going to be my first project as you have covered every single step. Great job. I can't think of anything more you could have done short of coming to the house and building it all with me. Thanks

Nice to see the corrected wroom-32E easyeda model in action. It took me a long time to let them correct it.

A great tutorial from start to the very end, you went through all the necessary steps without any skipping of content and with lots of aspects explained. I really enjoyed the whole video. Thank you Robert!

I have just finished the tutorial and this is just awesome. It is the moment about the truth. Thank you.

[@garyh8093]

I am absolutely awestruck from this video, amazing! I have watched some of your other Altium ones, and will be purchasing at least one of your Fedevel courses today. Can I ask one question? What about vias in pads? Is it something to be avoided? Guidelines? Thank you so much!

[@maximus6884]

Your channel has taken the community so far ahead!

[@RobertFeranec]

Thank you very much

[@klebs6]

totally agree!

[@RichardKCollins]

I knew this was possible, and you show all the steps. There must be ways to share working schematics with all required fabrication information. This is as cheap as buying off the shelf. I often see boards that have too many things and want to remove them, buy just what I need for an application. If you tied to the PCB maker then anyone could just pick what they needed and have it made. Thanks!!

[@RobertFeranec]

Thank you very much @richardcollins5549 PS: If it helps, a link to the finished project is in my pinned comment.

[@RichardKCollins]

​@@RobertFeranec Thanks. You are doing some outstanding things. But it still relies on your memory of how to find and click so many things. If we just had some way to check boxes to select what we want. I am sure a program, somewhere, could generate the required pieces to "print" something and let us order them. Me, today, I would ask for a programmable SDR to cover from milliHertz to GHz, storage to network drive. Yes, the link is helpful. I have been spending many hours every day talking with ChatGPT3 from OpenAI. It cannot yet, but at some point could, help people design the tools they need, program them for what you want to do, and have them completely ready to go to work when you receive them. Maybe I am just old, but after more than 40 years of clicking and typing arcane sequences of things, just to get computers to stay working, I am happy to be able to talk with an AI in complete and correct English sentences, using whatever words I want to express myself. It makes lots of mistakes and is not yet allowed to learn, but it saves me a LOT of time and improves my writing at the same time.

Another great video in KZbin'S history.

These practical videos are the best, so much to learn. WOuld be great to see more of them! these are really helpful! Thanks for the hard work on this

[@rajdeepdas86]

Thank you for the detailed description. I was thinking if raw ESP32 modules would require bootloader for connecting via Arduino.

[@andrewna4095]

Great video mate! Even though I have already made 30+ different PCBs, still learned a few new tricks! Amazing. Keep up the good stuff!

[@bubbl_media]

Thank you so much! This is an awesome tutorial, from the real beginning to a working pcb. No one shows so much details as you! Thank you!

[@pan_dmytrom]

Thanks for a great tutorial. I was able to make my first pcb using this skills and its actually working. Telling the truth, I am 100 LY away from hw designer 😂

[@avinadadmendez4019]

Hello Robert. I am just finishing a design using the ESP32-S2 bare IC. While using the bare IC instead of the module, you have to place a 40Mhz Oscillator, and you also have to design a transmission line for the RF input, and a Pi Network for transmission matching. Do you think you can cover that in a future video?

[@RobertFeranec]

RF for this kind of chips is on my todo list. Just hard to find someone for my interview video.

THE BEST VIDEO EVER! Thank you for sharing this free content to the community. I loved the video. Just felt bad that it's WAY expensive to order it

[@RobertFeranec]

Thank you. PS: You can always only buy PCB (just PCB is not expensive), buy components somewhere else and fit them by yourself. Also, as others pointed out, you can use Basic components, that would make it cheaper.

THANK YOU ROBERTS! YOU ARE A GREAT TEACHER! It was a breeze for me since I had already taken you introductory Altium training on Udemy 2yrs ago. Most of the steps, mouse movements etc (except the 3D view controls) are very similar to Altium environment!. And it is much simpler to use and get started quickly than Altium especially bcos of the component and foot print library!

[@yayser]

Where were you 2 months ago..I learned all by myself the hard way:) Anyway thanks for the great video!

Fantastic video ! I want to make my own ESP32 board, customized for the personal project I am working on and this step-by-step video is incredible !

[@alexk6745]

Hi Gael, I'm also doing my first custom ESP32 board. I'm making board to communicate via CAN bus as I do not wanna use wifi or any radio. I'm currently doing board with 4 connectors for PIR sensors. The esp32 supposed to send messages over the CAN Bus to ESPHome listening on CAN Bus. Then I'm gonna control my hot water solar heater again via CAN Bus. I'm planing to wire most important things over CAN Bus.

Di youtube hanya video anda yang saya cari.., anda hebat.. bisakah ajarin saya.. saya tertarik untuk membuatnya .., baru lihat video ini saya langsung auto subcribe ..

[@MatSmithLondon]

This is a great video. I would be very interested in seeing a video about DIY / custom ESP32 with ethernet and PoE on-board (using the cheap PoE power supply boards you can find on aliexpress for $5, they work well). Perhaps a video that doesn't spend too long on PCB layout (except where necessary, to achieve stability with ethernet) but a video that spends some time discussing what needs to be included in the hardware and code to achieve reliable ethernet. For example, I would really like to start making my own sensor boards with ethernet built-in, or even some DIN-rail host boards for connecting remote sensors etc. Thanks - I like your videos!

[@kitastro]

Learnt lot of things on this tutorial. Brilliant man he is.

[@jankowasli1203]

This is a great tutorial because it shows how a professional engineer is thinking during the actual work and I would like to thank you for that. I have a question about the process. How much time you had to spent on a research phase before recording the video?

[@trhosking]

Great video. Wouldn’t you save space for routing by connecting ground pins where possible and sharing vias rather than creating a via for every pin? Same for 3V3.

[@AndrewKiethBoggs]

Hi! General best practice is to place ground and power vias per connection and avoid sharing I believe. I have heard different reasoning behind this from different engineers but I am still learning myself. Overall, if you have the space, doesn't hurt to shoot for best case of better, low inductance connections to internal planes. I think for simple designs, probably doesn't matter.

[@denizhernandez2451]

Hello Robert I like your Video! But as a feedback for your next video: Maybe instead of just saying what you are doing it would be very helpful if you would explain why you are doing what your doing. For example at 2:23:00 you are saying that for the power pin you would use 2 VIAs, but it would be great to know why. Or also while placing the polygons, it would be nice to understand why you are doing that. just my two cents on a great video!

[@kevinjypiter6445]

Hey Robert, love your practical videos and also that Altium course you made! It's been such a huge help to us who don't do PCB work in a large company Is there a chance you'll ever make one of these designs with just the ESP32 SoC and build your own PCB antenna?

[@RobertFeranec]

Thank you Kevin. BTW: I try to talk to nordicsemi.no about making an RF video / design, they are interested, but responses to my emails are very slow.

[@MikeNugget]

Awesome tutorial! Also it will be very interesting to watch video how to deal with the firmware update in production when hardware has been already shipped to the customers.

[@dagarnenilssen]

Perfect video! Learn a lot (together with your series #1- #7 one year ago). Have a question: "Power Input Selection" there you use a connector "J4" - to avoid a manual connector - can this be replaced with a "Dual Common Cathode Schottky Barrier Diodes (e.g. onsemi BAT54CLT1G)", the same solution that was used in your "TINY" the project?

[@RobertFeranec]

Thank you. The 1117 regulator is not the best and if you take the lower USB voltage tolerance and decrease it by loses on the diode the voltage will be around the limits what 1117 needs. That is the reason why I rather used jumper. In the TINY project I used a better regulator, so we could use the diode.

[@Leif_YT]

Great video. Personally I've switched to the Pro Version, which is a nice step up. They've integrated a lot of feedback from the Standard version into the Pro version I think.

[@RoySATX]

I learned more from this video than the previous half dozen. Thanks!

[@jaroslavpsenicka]

Thank you Robert, it's very nice and detailed explanation and I really appreciate it. Few comments though: - I'd love to hear why you've chosen a particular component (e.g. the usb-serial chip) and what was the alternatives, if any - it would be great to explain what's the purpose of important components within the reference designs (e.g. the ESD protection diodes) and why we need them - you made few changes compared to the reference designs, I am not sure I always understood why and for what purpose - what's the reason for chosen form factor - making the board a little bit wider may allow repositioning the ESP chip between the headers and simplify the overall routing a little bit - using context menu for copy and paste drives me crazy :) - I love the trick with naming vias "GND" - I am not sure I understood why the bottom layer transistors are in fact not needed and why we need to place them in case of issues with the COM port (what issues?)

[@RobertFeranec]

Thank you. About info: It's a compromise - each small additional info will make the tutorial longer and longer. To keep it simple, I decided do not comment too much. You can find more detailed tutorial here: kzbin.info/aero/PLXvLToQzgzdea0sQXmpY8k4tfiXpkYIwO PS: If board would be wider, there is not much space for standard breadboard. Also, I intentionally avoid using shortcuts and keystrokes so everyone can see and repeat what I am doing.

[@atankent]

the best video i see so far. I am beginner. Thanks for showing all the steps. Just a question why the copper area /ground plane just cover the supply and GND only? Can we make it cover all the plane spaces?

I'd say you are nuts!🙂

[@ritzengineering]

You can have different design rule, esp at Track With and can decide for which type like GND or Vcc

[@vladoportos]

I'm a bit confused, I just finished a video where you had talk about not using power plane and ground plane to avoid noise... and now you have them here... could you shortly explain why, or if that even matter in this case... no idea how else would you route so much traces without, though :D
