how to make a nano 33 BLE enhancement board law compliant?

hi all,

Need to design a new PCB to accommodate both the:

  • nano 33 BLE board (procured from official sources) and;
  • optocoupler circuitry (enhancement).

Question:
Is it legal to obtain the schematics / eagle files from the arduino web site, add the enhancement and manufactured an enhanced nano 33 BLE board?

thanks in advance for any help.

That's the idea behind open source.
Your description sounds more like you will use the Nano as a module on your board.
Or do you expect to take the Nano as a starting point and expand and enhance it?

Do you have Eagle?

However, be sure to note that the "Arduino" and Arduino logo printed on the silkscreen on the bottom of the board are registered trademarks and should not be used without permission from the Arduino company. You can learn about that here:

thanks for the response.
I am open mind.
Would like to hear from the community the preferred alternative:
1/ to have a single PCB board incorporating the nano 33 BLE + optocoupler circuitry enhancement.
I will need to "clone" the PCB layout developed by Arduino and add

2/ design and manufacture an optocoupler board and interconnect to the nano 33 BLE via wires.
Either way, I will need to contract a PCB manufacturer, to also populate it.
Have downloaded and installed the eagle software from autodesk.
thanks

Hi pert,
thank you for the response.
I've inspected URLs provided, and found the answer:
I have designed a product that has an Arduino board as its core. Do I have to make my product open source?
Physically embedding an Arduino board inside a commercial product does not require you to disclose or open-source any information about its design.
Note that even if you include an Arduino board in your own product you have not made an Arduino product. You need to use your own name and logo on it but may say that it includes an Arduino board. For instance: XYZ Robot Car, with an Arduino Nano.

Note that the Nano 33 BLE can be directly soldered to another board, soldered down using header pins, or plugged into headers.

I’d go with #2. Put headers on your board so the Nano can be mounted with 0.025" square posts.
Especially as the Nano BLE is a 4 layer board.

Then the PCB can contain your thruhole or SM opto’s and whatever connectors or solder pads, etc. you are using and power supplies as needed.

If you decide to incorporate the Nano BLE into your board, then you will have to identify part numbers and sources for all the listed parts attached.

I don't know where you live, but rest assured it is YOUR product that must be legal, and has no bearing on what used to make YOUR product.
