Welcome to EasyEDA. Before asking for help about projects please read - and ensure that you have gone through the Essential Checks (4) and (6) - 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> A PCB is only half of the story in getting circuits to work. You can design a perfect PCB but if there are mistakes in the circuit that it is going to be assembled onto it then it is a waste of time and money reviewing it. To understand why this is so, please read (2.2) in (2) in the link above So for review purposes it is also much more helpful to you and anyone who may be prepared to give up their time to help you, if you make the whole project public and share the url to it.

For example a quick glance at your PCB shows that there isn't a single power supply decoupling capacitor anywhere on it. Please read and play with the simulations in: [https://easyeda\.com/andyfierman/Power\_supply\_decoupling\_and\_why\_it\_matters\_\-451e18a0d36b4f208394b2a2ff7642c9](https://easyeda.com/andyfierman/Power_supply_decoupling_and_why_it_matters_-451e18a0d36b4f208394b2a2ff7642c9)

Another quick glance shows that the copper pour needs rebuilding. Regards.

@Vipitec, You have a module that has a Wifi transceiver on it. It appears to be placed in the middle of the board over an area of almost solid copper (which we can only assume is ground plane). RF at 2.4GHz does not propagate through solid copper. You need to rethink your layout and follow the datasheet recommendations for the Wifi chip on your module.

Many Thanks for your help
