With the release of the latest 1.2.x of the board software package for the Quarto, recent versions of the Quarto now support reading and writing to the SD card. All Quarto's shipped after in Febuarary 2022 or later fully support the SD card.

To use the SD card, first in the Arduino IDE, go to Boards Manager and install the latest (1.2.x or higher) version of "qNimble iMXRT Boards by qNimble"

Once installed, open the UsageAndBenchmark example under SD,

Then you can put a SD card in the Quarto and run the example to do some basic operations and to benchmark the SD card. Or look at the example code to see how to list files, change directories, read and write files, etc.

If you aren't sure what version of the Quarto you have and if it supports the SD card, open the DeviceInfo example under Testing:

And when you run it, the output on the Serial Monitor should look something like:

Quarto Device Information
SN: 516
Device ID: qN-101.3.1
Firmware Revision: 1.26.46

If you see a Device ID of qN-101.3.1 or higher, you are ready to use the SD card. If you have qN-101.1.X or qN-101.2.X, please contact qNimble about your options for using the SD card with the Quarto.

I'm excited to announce that the Quarto is back in stock! Strong initial sales causes the Quarto to sell out 3 weeks after our product launch. And unfortunately the global chip shortage delayed getting more Quartos made, but they are finally here. And going forward, we will do our best to navigate these supply-chain challenges to keep the Quarto in stock. I want to thank everyone who ordered a Quarto and did not receive it promptly for their patience.

If you tried to contact qNimble via our contact us web-form from late November through early December and didn't hear from us, I'm afraid it is because we lost your message. When you use the contact us web-form, an e-mail is sent to us and in late November we switched e-mail providers causing these e-mails to get blocked until we later updated some security-related email settings. Frustratingly, submissions did get an auto-reply e-mail from us saying we had received the message and would get back to you shortly, but this sadly was not that case.

Because we have a privacy-focused website, we have no logs of the submissions and no way to know who contacted us. So let me apologize to anyone I ghosted. It was unintentional and entirely our fault. I'm sorry.

If you want to get in touch with qNimble the contact us link does work now, or you can call us at (720)-741-1556.

Three weeks ago, we launched the Quarto and a partnered with Vescent who is our exclusive US distributor (press release) and already we have sold out of our initial inventory. This is exciting as early sales were much higher than expected, but unfortunately it means that we cannot ship from stock currently and any new orders will be delayed. We are working to get more Quartos made as soon as possible, but given the global chip shortage, this will take longer than we'd like. For the latest update on availability and lead-time, please contact us.
