2/22/2026 - Research and Schematic

Martials that i read 1 https://documentation.espressif.com/esp32-c3_datasheet_en.pdf
2 https://docs.espressif.com/projects/esp-hardware-design-guidelines/en/latest/esp32c3/index.html
3 https://docs.espressif.com/projects/esp-hardware-design-guidelines/en/latest/esp32c3/pcb-layout-design.html
these 3 and https://www.ti.com/lit/an/swra117d/swra117d.pdf
firstly i had to make the schematic with the first 3 pdfs
there in schmatic
first usb c power

Filter crystal
main chip its the bare mcu not the dev kit

it all took from 8.5 to 9 hr and few reddit posts Lol
next update tmr(my back hurts from this long session)

2/26/2026 - Impedance Matching and footprint assignment

So first i did the impedance matching for the LNA and my anntena
so no reflection
but still the values are crude so not 100% effective

The footprint assignment and got the items on lcsc too!

and yes i do love pi filters :P
PI filter is the best

2/27/2026 - I spent way too much making this section look good

I spent way too much time making this section look good perfecting the symmetry around the USB-C connector and the CC resistors.

Totally worth it in my opinion.

Aesthetics before signal integrity!!!

3/3/2026 5 PM - Routing complete

I did route it completely no drc errors no issue
but i feel like its tooo big
i can easily make it smaller
see how much white space

I will make it smaller

doesnt feel like done even tho it is

3/3/2026 7 PM - Polish polish time

PCB Routing Complete

Layer 1

Layer 2

Layer 3

Layer 4

Routing is complete and PCB impedance calculations are done.

Now moving on to improving the overall look of the project.

3D Render

I initially tried to reduce the PCB size, but ended up adding more components instead.

3/3/2026 11 PM - a render after learning blender

learnt how blender even works
I had 0 prior knowledge

For some reason I even lack cuda like what
this didnt took long to render
but getting it right was the thing
and why is even moving a source / camera so hardddd
and with this organized the schmatic too!!
it did took me 3hr but idts i should report it cuz itts not towaeds hardware
