Maximum micro SD card capacity

rafaelss

Does anyone knows the maximum capacity of micro SD card that is compatible with ASIAir plus? Tried to use a 1TB with no luck.

Does anyone know the recommended capacity. I tried finding it in the user manual (which doesn't exist for the Air+ so I checked the AirPro manual), but it doesn't appear to be listed. I know Raspberry Pi s were rated to 1TB but always used a 128GB card successfully with mine so will go with 128GB for the Air+ unless I hear different. Would be nice to know however if someone out there has the info.

Just look at the Files Manager window of ASIAIR for the info.

You will find that ASIAIR will mount larger microSD cards, but the card image for the microSD is limited to 32 GB.

If you need more space for images, just add it by using USB storage. You can find USB Flash Drives and bus-powered SSD that are much faster than a microSD card.

For the first and second generation ASIAIR, you will still need the firmware to boot from the microSD, however. But you can leave out the microSD card completely in later generations of ASIAIR.

Thanks Chen. I don't want to hijack the original poster's thread, but I have the ASI Air Plus and what I'm understanding is that I can plug an SSD in the PC port and save data from exposures there? Alternately, I can use a 32GB microSD card (in the TF port) if I don't have an SSD available? Does the SSD need any pre-formatting or can it just be plugged in - good to go? Lastly, will there be an ASI Air Plus user guide coming out anytime soon?

If by "PC port," you mean a USB Port, then yes. You can plug a low powered, bus-powered in a USB port. A Samsung T5 series would do just fine. Faster NVMe SSD are just a waste, since the ASIAIR cannot really run them at full speed anyway.

The SSD or any USB Thumb drives will appear in the Files Manager window in the ASIAIR app, and you just need to select it for images to be saved there. On the ASIAIR Samba server, the external USB drive will appear as a volume called Udisk.

Does the SSD need any pre-formatting or can it just be plugged in - good to go?

Depends on which drive that you buy, of course. If it has not been pre-formatted, you can simply reformat it using ExFAT format on macOS, for example. Just use some format that can handle the capacity of the drive, and can work with Raspbian OS.

Lastly, will there be an ASI Air Plus user guide coming out anytime soon?

Based on their track record, I doubt you will see anything resembling a real manual from ZWO.

Thanks Chen. That answers my questions well.
