I need help with a schematic. i have created one it seams fine. and then i convert to pcb. but when i had the pcb printed the connections are not where they are supposed to be. if someone can explain how to share the project. i will but right now im a total noob here. i have now printed 2 different boards that are just paperweights. i dont want to waste anymore money. please help i see that even though the pins are in correct location they are moved around on the terminal block is that because of the numbers 3,5,4, I can use these i guess for protyhpe but the board is mislabled according to how it actuall wired. also i need to be able to label every spot from whats on schematic to make ease of connecting everything. ![pcbissue.jpg](//image.easyeda.com/pullimage/CADk3NgPin3CHdECV2Z5Ig1czvERxjICIzBMKKlg.jpeg)![part1pcb.png](//image.easyeda.com/pullimage/GEUYHgic2tMCq2Ki1wXW611p6gOM0uFe8uSKvFgU.png)

As a newcomer to EasyEDA,  it will help you to read carefully: [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> and the documents that it links to,  especially (1), (2.2), (4) & (6) in Welcome to EasyEDA, (2) in the above link.

Hi! Cleaning up your schematic to more readable form should be the first step. It is easy to make mistakes on layout if your schematic is not "up to par". Regards, Markus Virtanen HW / Electronics Designer

The pin numbering mismatch that you describe is lmost certainly because you have not set/checked the schematic symbol to PCB Footprint assignment. It is also likely the you have not set/checked the schematic symbol pin to PCB Footprint pad mapping according to your chosen device datasheet.
