@andyfierman [https://oshwlab.com/marczy236/ledring](https://oshwlab.com/marczy236/ledring) Here is the link. The polarity was the problem. Thank you so much!

"The polarity was the problem." This is because you have reversed the polarity of the Symbol Pins with respect to the Footprint Pads:  compared to what the datasheet shows:  To help you avoid these kinds of mistake please read (2.2), and especially follow the essential checklists, (4) and (6) in (2) in: [https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a](https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a)<br> <br>

Can you tell me how can I put some testpoint on the PCB and the schematic in Easyeda?

Exactly that kind of question is explained in (2.2) in (2) in: [https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a](https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a)
