Hi Robert,
Thanks for sharing your work!
i’m student,and i’m learning everything from you,i dont know how you calculate some value like bypass capacitor,filter,ferrite etc…
if you have prepare a file can i get it
thanks,and sorry for my bad english.

Hi Prasan, you are never 100% sure if everything will work (especially boards with OS are very tricky as for many things software support is required and it’s not only about correct electronic circuit – e.g. you can connect a peripheral wrong way and it will not work, even electronic circuit is correct or your PCB layout / placement can be wrong). Even if you can simulate some small circuits, it’s not possible to simulate whole design (or if it was, it would cost much more than build the board). I will be making a video about how I was checking this schematic, but basically start from referece boards and if you do some changes, be sure you check it. In this kind of designs, experience plays a big role – you have seen problems in past and you try to eliminate them in future.

Very appreciating for making this complex designs for open source use. I have some questions-
After completed schematic how do you check whether the design will work or not after production.
I’ve not worked with Altium yet but can Altium design simulate controller IC also with peripherals?
