ESP32 EPS-32s DEVELOPMENT BOARD SIZE ISSUE!

**Edit: Issue was fixed, dimensions change when converted to PCB and headers match perfectly with the ESP32 pins.** I'm basically trying to make shield for ESP32 EPS-32s DEVELOPMENT BOARD but the connector female headers doesn't seem to fit it. I got this ESP32 Dev Board from "User Contributed" class. Although all other similar boards from different users are of same dimensions, so I'm not sure what the issue is. When I try to fit those same female headers onto Arduino UNO they fit perfectly, however, with ESP32 Dev Board spacing between feamle headers seems to be half the spacing between pins of ESP32 Dev Board. Here's the link of my project: [https://easyeda\.com/editor\#id=\|828aa872d75147a5a3a4a285fe560887](https://easyeda.com/editor#id=%7C828aa872d75147a5a3a4a285fe560887)

Hello ; Don't get confused on the Schematic scale and the PCB footprint spacing, what you see in the schematic is relatively to what you want to design to represent the component but for the PCB what you link is the real footprint dimensions that should be set relatively to the component datasheet. The headers are 2.54mm spacing width and the ESP32 pins as well. ![scale component.JPG](//image.easyeda.com/pullimage/WwsrvccYWrtjzxwraU71xQhdU4pprFf4Vs8jWmf2.jpeg)![spacing PCB.JPG](//image.easyeda.com/pullimage/DfLuFkWxwzjEaDrWmQXPGSPGbAeGjlS1B7jmO1MW.jpeg)

@Saad201147, To help you understand the difference between the Schematic and the PCB representations of a circuit, it might help you to read (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)
