Thank you for making this video. Got everything working and it was a great start to custom keyboards!

Thank you very much! Fortunately I got two Picos laying around here and I wondered if I can use it in a Dactylus Manuform keyboard. So I'll definitely give it a try! I hope to see you soon on Twitch again. Have a nice day! :)

Really nice vid! It's thanks to your videos that I started building my own micropads

Thanks for this! Just started playing with KMK on a void30 board, and didn’t know I could hide the drive.

Hey dude. Only just discovered this now. OMG this is so much easier than the usual way.

in case I could make a wish ... a step by step guide for a 3d printed split keyboard handwired with hotswapable low profile switches :D :D :D (with enough keys for a german layout) videos like yours are much inspiring!

Thanks for this video, it may have gotten me a little closer to having a solution to my problem; a offline portable Bluetooth unit that will type my passwords into apps & sites at the touch of a button. As a keyboard this may work that way

Well I decided to go with the KB2040 and installed it with the encoder and the 3d printed case you’ve got Jan (had to file the usb socket and longer screw). First time with KMK so I’m sure I’m so I’m not that far into it. Not having vial support and no obvious way of OSL(1) or whatever the equivalent of QMK is kinda tripping me up at the moment. I have a nice little layout coming along slowly for a a portable Macropad so it’s nice to experiment with though. POG keeps overwriting my pinouts with board.GPMISO and what not so I’ve put that to the side at the moment as I’m assuming user error on the config. Keep up the fantastic work Jan, thanks 👍

I built a keyboard with the pico recently as well and love it for many of the reasons you listed. A couple of other things worth mentioning: only $4 per board - so cheap! Also, I found KMK to be easy to work with and slightly more powerful than QMK for a few things I wanted to do. I can edit my keyboard firmware on any computer with a text editor.

Wow, nice to hear about KMK! I didn't know it is so mature. Pico is crazy cheap... wow... while I would still like to have my keyboard wireless, I wonder if there is a possibility, to do it cheaper then nice!nano.

Awesome. Thank you.

Tolle Arbeit, danke. Als universeller Rückkanal könnte auch ein kleiner, simulierter USB-Stick sein. Dort kann eine Applikation Dinge reinschreiben wie Status, Farben, etc. Ich hab sowas für ein LED-Panel gebastelt.

I'm pretty sure the Adafruit guide on CircuitPython has a way to make it so that, when the drive does not show up, the program has write-access to the storage-drive. And making the storage-drive show up when plugged into your computer IS the switch you toggle.

Thank you so much! I have been looking at using KMK for a while now, but I didn't really like the idea of having the com port and drive constantly attached.

Great vid but do you need both uart pins ( full duplex) or can you just use Tx to create a half duplex connection in kmk for split keyboard?

You can do 8 bit inputs. Make sure to space digits tho so they don’t add up

though i haven't yet dived into custom keyboards (lack of time, money, and a general indecision about what to get), i very much appreciate your knowledge and chill vibes :]

Keep up!!!! I'm a big fan from Myanmar.

Can you make a video about how to wire the matrix? or do you already have one.

Projects like the GP2040-CE (which is for fighting game arcade controllers) have a built in web configurator. It kinda make me want to give a try and build a webserver within kmk. That would replace VIA with no aditional software, just by typing a url you would be able to have a gui to change the keyboard config, pretty crazy.

Hello, greetings from Peru, I would like to know what microcontroller I should use to make a full size keyboard, that it has for the RGB lights and the LED lights, also that it has one or another encoder? Thank you for your videos, even though I don't understand English well, you explain it so clearly that it is not necessary to have advanced English to understand you.

Great!!!

Hey, have you looked into the PICO W? I tried upgrading the 1UP planck with it, but failed. Supposedly, it is built with the hardware for bluetooth, but the firmware isn't supported for it yet. It seems like a quick way to basically upgrade any keyboard with the PICO to a wireless keyboard.

Finally the pico

Would it be possible to use this with a laptop keyboard? All I've been able to find about interfacing with laptop keyboards is people using a relatively expensive teensy and I am wondering why they didn't use something like the raspberry pi pico instead?

I'm using 2 of the USBC waveshare rp2040 for both halves of my dactyl manuform

Really hoping you do a small macropad demonstration. I Followed your code and LOVE the way it be changed on the fly. My attempts with doing a simple copy/paste macropad (Sequences) came to failure. I couldn't really understand where to put the code in provided by KMK and how it related to the pin numbers. Even finding examples on the internet was pretty hard (my google foo is weak)

It's great to see new content from you on YT! I have two picos with KMK that drive two different macropads made from a NeoKey Ortho Snap-Apart. LEDs and everything works great. But I sometimes do have issues having them connected while my computer boots. Also they freeze from time to time and I have to unplug and plug them in again. Did you notice anything like that with your macropad?

hi is there any way to add a thump joystick to a small custom keyboard using Pi Pico + KMK ?

Can you have an update for this macro pad with a rotary encoder like your previous build in pro micro. Very much appreciated

How many key input does it support? How many input does it support all together at once? Can I use chord typing? If not then teach us how to make chord typing keyboard...excited to see you do it

Hello Jan ! And thanks for all your nice content :) Could you point me to what tool is it you're showing at 1:40 for wiring to the switches? Thanks a lot ! :)

This is a pretty short and sweet primer on rp2040 for customs. Can you tell me though, I have a new EK68 and I find the VIA style software limiting. What I think should be possible is to desolder the completely unknown MCU on this board, trace out each of the pins with a continuity mode meter and slap a rp2040 in there and put in the details for the keyboard matrix. Then hook up the RGB and somehow plug these addressable RGBs into KMK as well? The board has triple mode, but I only care for USB connectivity. It has a rotary encoder with a push button top. Arguable is that can be picked up with KMK too. What kind of work would be involved in swapping out a mystery STM32 style MCU for a rp2040? It is a fine SMT pitch, so I guess soldering in wires to the rp2040 would require some fine soldering skills and equipment. Do you know if there is a STM32 SMT breakout board which you can solder in place of the original STM32 with breakout terminals ready to hook up to a rp2040 board?

nice video ... I wonder if u can run it at 1000hz polling rate...

I have a burning question for you regarding these things. it's for a future project. Am I able to have 2 x raspberry pi pico's on a board. - with 5 keys, but have each key Y-lead off to both pico's? I want 'F1', left-arrow, up-arrow, down-arrow & right arrow sent to TWO PC's at the exact same time? is that possible? what would be the best thing to do if it is possible? like, the wiring.... thanks

Just a thought. USB keyboard / HDMI or VGA to replace a VT100 terminal all in a keyboard package.

I finally made my split keyboard , using kmk and pico. I followed the instruction there but after I connect the trrs the button just doesnt work at all but if i connect just one side it work properly. Do you have any suggestion what just happened ?

Can i make a macro keyboard that has its own MCU with the pico. My job won't allow software on my work computer. I've purchased a macro keyboard that stores the keystokes but has very little storage

Hey! do you think a Pi Pico W or an ESP32 module can be used for a wireless macropad or an ESP32 module? Someone I know made a macropad for the PI Pico and its supported in QMK now so I am now writing the firmware for it

great video! What is the tool at 1:41 (to wrap the wires around the pins)?

Hi 🙋🏻‍♂️, thanks for your video. How is this tool called at 1:43, which you use to wire up the wire around the pins, I never saw this smart tool 😮

I recently watched your DIY keyboard project and was really impressed. I'm working on a similar project for gaming mice at and would love to explore a collaboration. If you’re interested, let’s discuss how we might work together

Is it correct to say that because there are enough pins available on the Pi Pico so that you could wire all six of the keys without having to use any diodes? Would it just be one row and six columns(7 pins)?

Will there be a difference if we use Pico W instead of Pico? Will the number of available pins get reduced?

5:50 there is a tool similar to via for kmk called Peg.

What is the 'simple solution' you mention about updating keymap from the PC? Can you post a link, ty.

Aww, sehe gerade Du bist ja auch aus Deutschland 😅 Danke für's Video, möchte ich unbedingt ausprobieren 😌 Funktioniert der Pico W eig. nun auch gut mit BT? Kannst Du mir verraten, wie sich dieses Werkzeug bei 1:43 nennt mit dem Du das Kabel um den Pin wickelst, sowas fehlt mir definitiv noch? Hält das auch ohne Löten? LG aus Hamburg

Can I use QMK(the one written in C) on Raspberry Pico Pi ?

I always thought it could be cool if you could switch the keyboard layout by just using a switch on the keyboard itself, do you forsee any issue with such a feature?

1:40 I'm sorry I know this video is old but what is this tool I need it Never mind I found one, thanks for showing me this exists

There is PEG for gui, bit annoying to use tho as it overwrites manual edited code.

Does anyone know of a discord where I could get some help. I've been trying to get my new ferris sweep keyboard to work for ages now and it just won't. I did everything in this video. There was even a premade keymap on the github that I was just able to grab. Yet when I press any buttons they just don't output anything. I have no idea how this is supposed to work. Please Help I want to use my keyboard and I'm losing it

Do these custom boards report to a pc/mac like standard generic keyboards?, I'd like to create my own custom keyboard with coded macros in the hardware for certain games (I have imagine storing them in an SD card or something), the problem I have with gaming keyboards and mice is that they require software to program macros and stuff that is usually detected and blocked by anticheat software. For any purists, don't want to bot, I want to avoid unnecessary use of energy and the tedium of repeating a task over and over, also I once developed tendinitis caused by creating potions in Ragnarok Online, not a fun experience and that conversation with the doctor was pretty uncomfortable lol. Thanks for any response.

What was the tool used in 1:41 I want one of those

How would a simple keymap update look like for your setup?

Include a html to read and display the config

Was anyone able to map Copy/Paste to their macropad?

Does anyone know what the tool at 1:42 is?

Does it have latency because python is slow?

i'm fink people need mirror keyboard to working like bodybuilder asymmetry of brain. i fink about two keyboard in one

Definitely Picos over Arduino Pro Micros at this point. Then again these bluepill boards have a lot of pins. The teensies with enough flash to run VIA aren't really complicated to use but if you program it once before setting the partitioning to work with VIA, that chip is never going to support it because the teensy firmware has, for some reason, locked you out of changing it forever.
