I'm reviewing a schematic design drawing that uses the Arduino Nano Connect RP2040 mounted on a PCB. I've found on the schematic, pinout identifications (e.g. "D8/GPIO20") that are shown in different locations that what is shown on pinout references for the ANC.
(The discrepancies are on pin D8, D11 & D13.)
The EE says "...the pin location is correct. Please check the designator number not the location on the schematic. On the schematic, the pin location is not the PCB pin location, the designator is. This schematic symbol is taken from ultra librarian..."
I've searched for the ABX00052 and 53 on Ultra Librarian, which says nothing is available.
The pinout ID mismatch is quite confusing and makes it difficult to do double-checks on proper circuiting for the PCB. How can I cross-check pinouts shown on drawing VS the pinouts shown on mfr's documentation?
I am not sure what you mean by this. It is normal on a schematic to have the physical pin numbers in any actual order on the rectangle that denotes the board / chip. It is only very cheap schematic software that will not allow you to define any board / chip pin to anywhere on the rectangle.
Yes relating that schematic to the physical position on the chip requires two step thinking. You say to yourself "D8 is on pin 26 and then locate pin 26 on the physical board"
Remember the schematic and physical layout are two totally different things doing two totally different jobs.
I can't see any discrepancy between the schematic and the physical layout of the board.
