Hey Noah! This has been immensely helpful. This is so good to help me make a custom TKL keyboard. I am eagerly waiting for Part 3 so that I can send an order to JLCPCB to get this done and start using my "own" keyboard. Thanks again!

For those following along: at 15:45 when Noah brings in the new capacitors to the PCB editor, he flips them to the back of the board. He doesn't mention it explicitly, so it is easy to miss. P.S. Thank you Noah for sharing this awesome tutorial. It has been very educational!!

Part 3 when?

What kind of knowledge is required beforehand to understand this and be able to design one from scratch? Will a basics on circuit boards be enough?

quick question, do we not need some kind of pull-up/pull-down infrastructure for the switches to define a stable off state?

Thank you for a detailed video. Would be perfect for my own pcb creation.

i love you

THANK YOUU! I was super confuse with the process to order the plates from JLCPCB

6:10 J stands for Jumper. I think that the letter just stuck around connection interfaces even as we moved on to using more advanced couplers.

for the pcb's do i need a 5v or 3v pro micro controller

How do i get to the "Choose A symbol" part at 0:53 ?

Is there any difference on the routing of the buses with HS switches ? I was following the part2 of the other video, have to finish some way or another

Just a minor issue, the 100nF decoupling caps should be placed as close as possible to the processors supply pins... While it will probably work as is, I would follow the datasheet recommendations... C4, 6 and 7 can be moved much closer with very little effort...

Hi, I was wondering how can you put a potentiometer in there? What to do with the wires? Do i still put a diode in? What do I need to do?

Why are you implementing both a jst and usb-c connector?

Can the USB pieces be easily split off into a daughterboard?

Love your videos! Super direct and informative! I'd definitely love to see some content around wireless chips or onboard CH552T (for fak firmware). A split design would also be really nice to see. Perhaps IO expanders too? Hahha these are just some ideas. I'm loving the current videos as it is already!

Now, how to write firmware for that STM32? Can anyone put me in to right direction?

Does any one have a template for the LQFP-100 package?

Awesome video! The best on youtube imo. I am curious to why you could not fit the ISO-Enter key in the layout (54:24)? Today we see some PCB's that are ANSI/ISO Universal. I was curious to why you didn't add that same universal feature to this PCB?

Great video! Great idea to use the esp32 designs to skip reinventing the wheel. I've been really enjoying your content. Have kicad installed and plan to make a full sized iso layout board. It would be amazing to see adding features like encoders for knobs (should be fairly easy), leds via i2c or something, how to flash and customise firmware, and how to use something like the esp32 to also enable 2.4ghz connectivity via a dongle.

So good video. Do you make video about hall effect keyboard pcb design?

Thank you, your video helps me a lot. I am currently making my first split keyboard from scratch. And since I’m not good at English, the learning curve is very steep for me. Until I found your tutorial. If I finish this project I may record a tutorial video in my language and will credit you.

I'm very new to all things electrical, but I'd like to build my own board. How do you learn what things require resistors and capacitors where and how they connect together? Is it on the spec sheets for all the components?

Hello sir , In kicad 8 their is no symbol for MX switch ,can i replace this switch as normal push switch ,or pls give me the symbol for switch and their footprint with there size . pls replay as soon as possible ..Thank you

Could you do a video adding RGB to one of these boards? do you add in the LED or do you just swap out the diode for an LED?

What a legend, this video is exactly (to the letter) what I was looking for! Can you flash the bootloader to the STM chip over the USB? I've only used blackpills in the past where I needed to use the stm usb to serial flashing tool connected to the serial pins. If these pins aren't exposed how do you get the bootloader on the chips, does JLCPCB factory flash them for you or something?

Total beginner about to take on my first custom PCB and this is the BEST video i've seen yet so thank you!

Part 3 when?

hi, when I'm importing the *JSON file from an ergonomic keyboard, I get this message: "You must enable rotation mode if there are any rotated keys!" how do I enable this? I'm using the 8.0.1 version of KiCad

I have been watching a few of your videos over the last week and I love how the videos are made. Please make more as I assume you already intended to. :D

You're very thorough and concise in your explanations, and it's a gift to have been clearly shown a way to design using this template. Thank you for making PCB design so much more accessible! One minor thing I can't get to work is what you do at 20:03 - switch out the USB footprint for the marbastlib version. I followed the same exact steps and updated from schematic, and the footprint updated successfully. However, when I go to the 3D view, the USB still doesn't show. I'm curious if there's an additional setting you may have that's different, or perhaps you may know of a reason why the 3D model for the USB header doesn't show even though I updated to the marbastlib footprint?

This is gold! Watched it 2 times and learned a lot. Would really enjoy a part 3. Maybe even with jlcpcb parts assembly? Thank you!

Would you recommend going completely crystal-less for USB operation? Or is it better to include an LSE crystal in the design?

Very informative, love the video, watched all of it. But why use Kicad on windows xD? Such a beautiful piece of free software on a windows 11 puke os

How did you rotate the Mcu like that? I’ve been trying to figure it out for so long and I can’t figure it out.

is it possible that you can make a tutroial on how to make a magnetic mechanical keyboard, i've couldnt find a video about it

Any ETA on TKL PCB design part 3?

I vote recreating a Nice!Nano for the next build :)

Is there a follow up video?

Are u ever gonna revive the ti84 ke?

I was planning on making a keyboard using an already assembled Pico board. Does most of this tutorial allow that? Would I have to do anything special? I assume it would just be skipping to when you actually add the keys to the schematic.

Hey what should i change if i want my board to be 8k mhz

Hi Noah. I've been following your TKL series the past few days, and now I only need to route the matrix. I already have slight knowledge how to do this with the rows and collums, so I'm just asking now if it's possible for me to finish the project by routing the rows of the diode catodes to 6 different IO pins, and my 18 Columns of switch inputs, to 24 IO pins on the RP2040, and then finish by flashing the QMK firmware onto the chip? Also, would you recommend using Western Duplex Matrix, or should I just keep to using one node pr. row and column individually. Great tutorial, and many thanks for the good videos!

thanks that clears things up

I am currently using STM32F072C8T6. Any difference with your STM32 model that you are using?

Awsome

Thank you for sharing your template. For V2 of my keyboard design, I was planning on painstakingly copying a schematic for a ProMicro and probably messing up along the way. Your videos have basically taught me KiCad.

Really good, as usual, love the KLE Placer and the parts list. Thanks!

ah finally. great tutorial Noah. Thanks for sharing !
