Made the Bom and finalized everything

Completed the BOM , most of the parts are in one single website ( got them for very cheap and free shipping ) only the PCB's are from JLPCB , cant find anything cheaper from them

And here is a cool image for banner :)

Updates

While making the BOM , i couldnt find the micro SD Card Reader locally and the international import was costing a lot in shipping , so i have decided to use a general connector with a cheap sd card board for arduino

Updates to Schematics

Updated PCB!

Finalised the CAD Design

So this will be the final look of the Shadow Pico!

I have added the holes for usb

On front side there are holes for the SD Card , External Connector and a Slide Switch for Power.

To attach the bottom case to the top case I have used ridges!

FInally Completed the PCB

This is the PCB , its under 100mm by 100mm , i have routed everything with ground pours at front and back for the GND , added 3 mounting holes ( there wasnt any space for the 4th one ) , and i think it will be sturdy enough even with 4

Completed the schematics

Honestly the schematics were a mess , the hardest part was getting the charging right , i have made groups for different parts of the pcb so that it is easier to understand!

Decided the parts i will use

These are parts i will use , i am using raspberry pi pico , a micro sd card reader , sound , leds , TP4056 for charging and waveshare 2 inch display with 8 keys and a reset and charging button
