PCB Complete!

Yup, PCB development is completely done, and i'm very happy with the results :D It looks amazing

Routed it during school and here it how it looks like. I'm still unsure whether to get assembly or to hand-solder, i'll see tho!
Now adding some silkscreen is left and making the repo really nice and then boom i'll submit

Complete change

Okay, so i completely changed the idea, instead of making a small one, i'll make a not so small one.. here is what it looks like now:

i cannot decide whether i should get PCBA or not. i'm making the module as per PCBA because the RP2354A is out of stock on JLC, thus i added W25q128jvsim too. but that will have space concerns, thus i will have to think what to do..

Routed the PCB(about 35%)

Update: i am doing with option 1. i'll be ordering the buttons and LED from a cheap seller in india, so the shipping costs are only $0.54 :yay:

I also routed the pcb a little bit, here it is:



^this passkey is not reall small

Completed the Schematic(for now)

I'm still unsure what kind of form factor i wanna give this key, so i just made the minimal schematic for the passkey, i'll be using the USB on the PCB, no extra component. I want to minimise the cost per key for this one!

1. i have thought of two things, the USB on the back side of the PCB, and components on top, shrinking size
   
2. components and the usb footprint on the same side.
   In 1. the size will be really small but the button and the LED will be on the other side, if i dont want that, i'll have to solder both of them myself. option 1 is much better size-wise but choosing option 2 will get work done easily.
