Hello! I'm having some lexical issues. What is the meaning of "broken out pins" and/or "pins were broken out"?
I'm trying to figure it out, and I think "broken out pins" are the holes on hats in which to insert a header, but I get confused when I see "pins were broken out". Do they have different meaning? When is a pin broken out?
Thank you, Aliana
In general pins 'broken out' or 'brought out' means made electrically accessible.
For example the SOC has many additional GPIO's other than the 26 found in the 40 pin header.
Those additional pins are not connected to anything so not 'broken out'
A specific example is the older SOC (don't know about RPi4?) have an FM radio built in however the antenna (aerial) pin is hidden under the SOC and is not connected to anything... So imposible to use the FM radio as the pin is not 'broken out'.
Unless specified otherwise my response is based on the latest and fully updated RPiOS Buster w/ Desktop OS.
