Devlog: PCB Optimization for Mirkonlmtoelra

Overview

This is my first devlog for the Geeky project. I’ve been diving into datasheets and schematics, learning a lot along the way. My main goal is to create a PCB that is 100mm x 100mm or less while keeping it efficient.

Goals

• Fit components into a compact design without compromising quality.
• Develop a clean layout that functions well.
• Ensure solid signal and power distribution.

What I’ve Learned

I’ve been researching the topic and gathering information. Here’s what I plan to do:

1. Component Review:

   • I’ll start by analyzing the datasheets for each component.

2. Schematic Design:

   • Based on what I find, I’ll create the schematic diagram.

3. PCB Layout:

   • Design the PCB layout, making sure to stay within size limits.

4. Prototype:

   • Once the layout is complete, I’ll order the PCB.

5. DIY Assembly:

   • I plan to solder everything myself, which should be a great learning experience.

I created a simple schematic for an entire microcontroller. I plan to enlarge it on bigger footprints since I am not focusing on creating something elaborate; this is just for simple tasks.

Components Used:

• RP2040
• USB-C
• AMS1117 3.3V
• 12MHz Crystal
• W25Q128JVS
• Pins with voltage outputs

2/1/2026 10:40 PM - Routing and Connecting Wires on PCB

I know that pcb is big but is less than 100x100mmm and this will help me understand + better projects

We're on the final stage: routing and connecting the wires in the PCB schematic and finishing it up. I'll check for errors right away.

I want to be clear: I am not interested in impedance and signal lengths. This is a simple project, and worrying about those details is overkill.

I admit I have a few vias, but for my use, this doesn't bother me, and reviewers should consider this. This stage took a long time because I wanted everything to be well-connected, and it is. I won't change anything; the project stays as it is, and I am wrapping it up.

Below, I am sending the 3D view of the schematic and the DRC showing that there are no errors.
(fun fact i forgot to sleep)
