Devlog 2

So, I decided to scrap the RP2040 idea because it was a little too complex. I decided to just use a Raspberry Pi Pico instead.

Also, I didn’t really like the previous 60 percent layout, so I changed it to a 75 (ish) percent layout (shown in the screenshot)

After all that, I got to work on the actual PCB itself. I placed down everything in the schematic and started to route the matrix rows and columns.

I haven’t decided which pins to put my rows and columns on, but that’s for future me lol. I want to make sure the placement is convenient for routing the traces because I don’t wanna end up with a messy board.

I randomly wanted to build a keyboard for some reason… I had to choose which layout to go for, and I chose the 60 percent layout because it’s compact enough to fit and carry around.

Then I had to decide which microcontroller to use.
My options where:

• RPI RP2040
• ATmega32U4

I decided to go with the RP2040 because it’s newer.

Using KLE NG, I made what my keyboard is suppose to look like, then started on the schematics of my keyboard. It’s a 14 x 5 matrix, so I’ll use a total of 19 pins on my RP2040.I also did the layout on the PCB, along with the stabilizers too.

I’ll (try to) wire up the RP2040 and USB C ports tomorrow. We’ll see how that goes. I have absolutely NO idea where the USB C port is suppose to go, but that’s tomorrow’s problem lol.

Whoops I forgot to attach the schematic and now it won’t let me attach it 😭😭😭

I followed a tutorial on how to start making my own OS. All it does right now is print hello world…
