I'm working with the new Arduino Uno Q schematic and noticed there are many useful pins exposed via test pads. I tried to find more about the test pads but could not find any assembly layout map or silkscreen guide indicating where these physical pads are located on the top or bottom layers of the PCB. is there any document mapping every test pad of Arduino uno Q.
Hi @amitf. You should be able to learn about these by examining the PCB CAD design. The open source design files are available for download from the "CAD Files" link under the "DOWNLOADABLE RESOURCES" section of the product documentation page:
https://docs.arduino.cc/hardware/uno-q/
You can view the design by opening the .brd file in the Allegro X Free Viewer application. It is available for download from this page:

Thanks for the link!
I noticed the files for the main UNO Q board are in Allegro format. However, the CAD files I downloaded previously for the UNO Q Media board were actually Altium files.
Is there an Altium version available for the main UNO Q board too? I'd prefer to use that if possible so I don't have to download and set up the Allegro X Free Viewer just to check the test pads.
Unfortunately, no.
The Arduino hardware design team use Altium in house, and so most of the CAD files are in Altium format as you noticed. However, the UNO Q was designed in collaboration with Qualcomm's team, and so their preferred EDA was used instead. This is the reason for the different CAD file format.
