They are all broadly similar, all being based on the ESP32-D0WD core, but have
some subtle differences between variants around PSRAM inclusion and camera pin
mappings.
The ESP32CAM "unit" product (SKU: U007) has no PSRAM and maps the
"Pixel Data 0" (Y2 GPIO/OV2640 D2) camera pin to IO17 rather than IO32 as is
the case with most other M5Stack ESP32 camera devices.
The ESP32CAM also requires the "hmirror" and "vflip" camera configuration
bits setting in order to capture a true image.
The relevant M5Stack pin configuration documentation can be found here:

* Expand gitignore to cover files created by Visual Micro's Arduino IDE for Visual Studio
(cherry picked from commit d6209c79ea16a26564fe27e74e5f277160129847)
* Also ignore VS project files

If you develop on windows and need cr/lf files, see this:
https://git-scm.com/book/en/v2/Customizing-Git-Git-Configuration#_formatting_and_whitespace
Git can handle this by auto-converting CRLF line endings into LF
when you add a file to the index, and vice versa when it checks out
code onto your filesystem. You can turn on this functionality with
the core.autocrlf setting. If you're on a Windows machine, set it
to true - this converts LF endings into CRLF when you check out code:
$ git config --global core.autocrlf true
With this step we remove all dependencies, but git. Mac and Linux come
with Python by default, so they will keep using get.py to update the
toolchain and support binaries. Windows users have an "All point and
click" installation option that requires only git and Arduino to be
downloaded.
Fingers crossed :)
