That doesn't seem unusual to me, given that to get to this page you either have to be searching for the specific terms already (and know what they are) or come from the homepage -> RP2040 (Raspberry Pi Pico) projects -> Custom serial bootloader for the RP2040 -> Preliminary reading RP2040 boot sequence

I came to that page directly from the front page of HN. I think it's reasonable to assume a significant portion of their traffic today directly to this page didn't already know what RP2040 is. Missed opportunity to educate readers.

It might be nice, but most web pages aren't written with Hacker News in mind. We share them anyway.

You should expect to sometimes encounter documents where you aren't the target audience and you have to look up terms.

Do you want every single subpage in the world to reexplain its context again?

Do you expect every SF Chronicle article to explain to you what SF is?
