Hi. the Arduino RP2040 board power rating says, “Circuit operating voltage: 3.3V, Input Voltage (VIN): 5-21V”, does that mean I can connect a battery source that is rated between 5-12V? If so, and I want to connect to the board an RGB whose power rating says, “Supply voltage: 5V DC, Logic level: 5V (often accepts 3.3V)”, will connecting a battery greater than 5V damage the RGB? Thank you

Hi Todd,
Welcome to the forum,
You are correct!
You might want to use a regulator to maintain a stable 5V for the LED strip.
And it might be worth grabbing a logic level converter to cover your bases for the logic voltage

If the board’s circuit operating voltage is 3.3V, won’t a battery source that is greater than 3.3V damaged the circuit’s components? Thank you

Hi Todd,
The operating voltage is the level that the pins put out on a logic ‘high.’
The input voltage is how all of its powered, it just has to be between 5-18V
and is regulated down onboard.
Are you following a guide? We can verify if each of the connections are correct

No, not following a guide, just trying to understand basics for a potentially major project.

Hi @Todd277059,
I think I can see where the confusion is coming from.
The Arduino Nano RP2040 Connect can accept 5-21V.
The Logic Voltage or Operating Voltage of the board is 3.3V, this is the max voltage the I/O pins can output/handle.
If the LEDs say they use 5V logic but can handle 3.3V, the Data and Ground pin should be fine to connect to the I/O pins of the Nano. However this is where a Logic level converter such as this one can be helpful.
The LEDs will still need 5V to be supplied to the Voltage In and Ground to work. You will just want to make sure you don’t connect the 5V to one of the I/O pins of the Nano.
I hope this clears up you question.

this is great, thank you, i’ll check out the guide on that page to learn more.
also, I take it you are staff at Core Electronics? Does Core Electronics provide a chargable service whereby I can privately email you what I want to do and you provide advice, parts list and instructions on how to assemble/connect what and where?

Hi Todd,
Yeah Aaron is staff (the shield on the profile).
They don’t have a chargeable service but an engineering consultant would be an option.
If you’re keen on learning the forum is a free place you can get help from staff and community Makers/engineers
