Hi, The PCB I have is marked S/N: 4269.03.0626 but the picture over the board layout, for the hitex Shieldbuddy PCB
as I have found do not comply. Can you help me and present a picture over the board layout as will comply to the PCB with S/N: 4269.03.

Hi, I can also confirm that the images of the front PCB and the back PCB in the User Manual for the ShieldBuddy doesn't match board revision 4269.03.06210_B1 (see attached images from the User Manual and my actual board with that revision number).
The User Manual (Revision C) is here:
I've gathered information from the following forum threads:
...but, the build instructions for converting ShieldBuddy from 5V power supply and I/O for the MCU to 3V3 needs clarification - marked below as: a) 1 to 9, and: b) 10 to 13:
a) where are the following components located? ("ITIK, but..." is here short for: "I think I know, but can't be sure because information about board revision 4269.03.06210_B1 is missing in the User Manual for the ShieldBuddy"):
1. D507 (ITIK, but...) - populate part number MBRA340T3G - but where is it located?
2. R520 (ITIK, but...) - old value is 100K, i.e. remove and populate new value 54K9 - but where is it located?
3. R519 (ITIK, but...) - not populated, new value is 0R (short circuit) - but where is it located?
4. JP501 (ITIK, but...) - ok, remove since we don't want to short circuit 5V and 3V3 - but where is it located?
5. R320 (I'm clueless...) - old value is 0R (short circuit), remove component - but where is it located?
6. R319 (I'm clueless...) - not populated, new value is 0R (short circuit) - but where is it located?
7. R323 (I'm clueless...) - old value is 0R (short circuit), remove component - but where is it located?
8. R324 (I'm clueless...) - not populated, new value is 0R (short circuit) - but where is it located?
9. U502 (ITIK, but...) - my component is marked "POPV" - is that U502? which manufacturer and part number is that? and it shall be replaced with MCP121T-315E/TT instead, right? but where is it located?
b) lack of information about case code in inch or mm (CC), power rating (W), E serie (E) and tolerance (%) for the following resistors: - what are the correct values for CC, W, E and %?
10. R520 (ITIK, but...)
11. R519 (ITIK, but...) - short circuit (doesn't have to be a SMD component, but would be nice to populate - only CC wanted)
12. R319 (ITIK, but...) - short circuit (doesn't have to be a SMD component, but would be nice to populate - only CC wanted)
13. R324 (ITIK, but...) - short circuit (doesn't have to be a SMD component, but would be nice to populate - only CC wanted)
Kind regards,
