Hi there!

1. Yes, it definitely makes more cost-effective sense as well as saves space to use the TinyZero with accel rather than the TinyDuino and USB Board.

2. I tested out the program and it looks like it's compatible as long as the BMA250 (accel) library is updated.
It looks like the current software on the site isn't working when downloaded form CodeBender, so I'll update that. In the meantime, I attached the updated program that works with TinyZero.

I hope that helps!

I sent you an email to get you a replacement. If you're in the US, I might exchange the boards since I'd like to see what's going on with your board.

The 3.7V batteries we supply should be sufficient. Are you still encountering issues?

If you are unable to see the device at all in the device manager, the problem is likely a Micro USB cable.

I would recommend trying to re-install the WCID driver using Zadig.

Is LTO disabled in the Arduino IDE? Are you able to see the port that the Saber is connected to?


Hmm. It shouldn't get hung up on a file just due to its size. It may be taking a long time without providing in-progress feedback, or it's possible there is a DRM blocking your ability to convert the video.


The format is custom. TSV stands for tiny screen video.

Ours GPS Tracker project isn't able to communicate real time results. As you have seen, you can access the data after the fact which might not be ideal for tracking a falcon.

The hornet GPS component you mentioned would need a board built around it to connect with other electronic components from what I'm able to understand from their website. If you have more information on how the chip is applied to products, I'd be happy to read through them.

A few years ago, we did prototype a GPS bird board with solar panels for recharging and some other useful sensors to assist an Oklahoma college, but it's a pretty involved project that would involve a lot of software time. It's on pause until we can get a grant for funding, or work with a University or some team to collaborate with us.

Yes, you definitely had the test code. Sorry about that. I'm glad you were able to sort it out and get the updated software from the IDE.

Hi there,

The .tsv format is the only format that will play on our TVs due to their programming.

You can convert mp4 to tsv using the converter, but the TV's will not play mp4 videos innately. The converter is built around ffmpeg. You could use a different tool and formatting if that's what is preferable, but you would be responsible for the programming.

Hi there,

Yes, you will need to plug the SD Card into your computer directly. The kit comes with an SD card adapter that you should be able to use with your computer. If you do not have an SD Card port on your PC, you will need to get an adapter to do so.

When you try the original example videos - are you removing all of the videos you put on the SD Card? The TV will play videos in the order they are added to the SD Card.

Can you send a video of the behavior you are seeing? It's possible that the hardware isn't plugged in completely. I would recommend removing the SD Card, opening the back of the TV, and re-assembling the hardware in the TV to ensure the connection between the TinyScreen+ and the SD & Audio TinyShield is complete.

The settings menu is the best way to set the TinyTV back to default settings, but you could also try re-uploading the program by following these tutorials:

Let me know if that works for you!

Hi there,

Can you attach one of the erring videos?

If there are special characters, or if the title is longer than 50 characters, the videos will not play from the SD Card. More details on the FAQ:

Do the mp4 videos work when you play them on your computer before you converted them?

The LEDs we use are size 0402 and are color variants of this type of LED: APHHS1005SURCK by Kingbright

Here's one of their datasheets:


I think the best way to find out what works for you is to test the best and worst resolutions. The videos you convert get resized for a 0.96" screen either way.

The possibly important difference if you are adding a lot of different videos to your TV is that the lower resolution video would take up less space on the SD Card.

Hi there,

Did you put any tsv videos on the formatted 32gb card when you tested it?

What operating system are you using (MacOS, Windows)? Can you share a screenshot of the exact error message? Do you have an SD Card adapter between your computer and the SD card?
