As already discussed the ASIAIR Pro (which is a Raspberry Pi4) can be operated with the SM OS. Just flash the SM OS to a fresh microSD card and boot
the ASIAIR pro up. However, as mentioned by Laurent.Wolff, in this "normal" Stellarmate configuration the 12 volts power output ports do not operate.

I have an ASIAIR pro in use, the 12v ports are configured "on" or "off" in the ASIAIR app. If you turn on all 12v ports in the App, then the power ports are
immediately available upon booting the ASIAIR with the ASIAIR OS, no need to start the app on the tablet, so the configuration is stored within hardware
configuration.

I had a closer look on the ASIAIR pro microSD card and looked into the file config.txt. The power outlets are configured there, when they have been turned on
previously by the ASIAIR app.

So, I took the Stellarmate OS microSD and edited it's config.txt.

Simply change the config.txt in the [pi4] section and add 2 additional lines in front of the [all] section like this:

[pi4]
# Enable DRM VC4 V3D driver on top of the dispmanx display stack
dtoverlay=vc4-fkms-v3d
max_framebuffers=2

# I2C Bus
dtoverlay=i2c3,pins_4_5

#Enable 12v gpio output <


new line
gpio=18,12,13,26=op,dh,pu <
new line

[all]
#dtoverlay=vc4-fkms-v3d

I have attached the config.txt file for those of you who are not familiar with file editing. Just copy the config.txt to the root directory of the SM microSD card.

When booting up the ASIAIR pro with the edited SM microSD card, the power outlets are available upon bootup.

I have successfully operated both the camera cooler and the electronic focuser using the 12V power ports with Stellarmate.

Hope this helps anybody who wants to operate the ASIAIR Pro with the much more powerful Stellarmate OS!!!!!!!
