TinyDuino Processors & TinyShields / Re: How to Measure TinyZero Ba...

Last post by bibletech55 - October 16, 2025, 09:41:24 PM

Thank you for the additional info! So the MKR Zero board defines (as a macro) the term ADC_BATTERY, while the TinyZero does not.

Fix it by checking the TinyZero schematic to find the ADC pin used for battery sense...

I double-checked the schematic again, but I couldn't find any analog pins for the circuits with the following headings:

• Lithium Battery Charger
• Battery Connections
• Power

However, at this time, there is what appears to be a voltage divider next to the circuit "BMA250 Accelerometer". This voltage divider seems to output to pin AD4. Is this the correct analog pin? If so, how do I translate AD4 to the proper input term for analogRead()?

TinyZero's variant does not expose ADC_BATTERY so the symbol is undefined.

After searching on GitHub, I was able to find the variant for the MKR Zero, but not the TinyZero. Does the TinyZero not have a variant on GitHub? Could that be why ADC_BATTERY was not defined for the TinyZero?

I could not find a search Icon so forgive me if this has been posted many times.

Is there a UK supplier?

Usually the description or display is in the TinyCircuits Thumby product. The "Play & program" section and API documentation, MicroPython / Blockly programming guide are probably the information you need.

TinyTV & Tiny Video Player / Settings Menu on Tiny TV 2

Is there a Settings Menu on the Tiny TV 2 that I can access?

Not sure how to get to it.

Thanks in advance for the help!

Hi Joe — try right-clicking the TSV Converter and choosing Open to bypass Gatekeeper. Make sure it's the latest version from TinyCircuits' site. If it still won't launch, run it via Terminal or contact TinyCircuits support for a demo TSV file to test.

New Product Ideas / Re: Lidar Lite v3 Tiny Circuit

Last post by larrygrichards - October 06, 2025, 01:22:37 AM

Yeah, I totally get that! The Lidar Lite v3 is great, but that $150 price tag really hurts. A smaller, more affordable Tiny Lidar version would be awesome, something compact but still accurate enough for small robotics or DIY projects. Hopefully, someone makes one soon!

The converter tool uses ffmpeg, the commands it uses are below.
They are basically the same between models, just changing the resolution and increasing the quality on TinyTV 2.

It would be more work to automate the normalize option, but this is the command it uses:

Code Select Expand

ffmpeg.exe -i "in.mp4" -vn -ac 1 -af aresample=10000,aresample=async=1000,asetnsamples=n=210:p=0,aresample=osf=u8,volumedetect -f null /dev/null
You would run this on the file and parse the max_volume result. A result of max_volume: -1.9 dB means you would use volume=1.8dB in the commands above instead of volume=0.0dB

Will the associated battery be drained or will it truly charge?
