I have made sure that the SDHC card is formatted correctly. I have tried both cards across 3 different RT1062 camera modules with the same result.

Relevant Info: I actually tried a separate SD card from my 3d printer at first. Initially it did not work. After inserting/taking out multiple times it started working randomly. I was running a tflite model/person detection script and the camera froze. The SD card got corrupted and was unrecoverable. This is when I switched to the card linked above. Now I am unable to get any SD card to be recognized. With an SD card inserted or not I get the same memory via the drive associated with the camera (only showing internal mem).

Next Steps: Based on forum content and suggestions from Ibrahim I will try an EVO Plus Class 10 Micro SDHC next. I will also try to partition the 16gb card to 2GB and try again. However documentation implies 16GB is well within limits. (and is necessary for the project that I am evaluating the camera for).

Just checked and it’s working on windows for me with an 128GB PNY flash card.

We use FATFS which is a pretty widely used file system driver for this. I’d check that the card has a standard MBR and not something else for the partition table. You can see how the partitions are formatted in Windows via the disk management.

Does this seem adequate?

It should work if it has an MBR.

Here’s the one I have: Amazon.com: PNY 128GB Elite Class 10 U1 microSDXC Flash Memory Card - 100MB/s, Class 10, U1, Full HD, UHS-I, Micro SD (Pack of 2) : Electronics

FWIW the folks over at the PJRC Teensy Forum have recomended NOT to use the windows file manager to format SD cards but rather the SD Memory card Formatter at the SD Card Association. “SD Memory Card Formatter for Windows/Mac | SD Association”

Thank you for the information. I have tried this software as well. You can see this in the first image of my original post.
