- Wed Dec 28, 2016 1:46 am #60047 I'm using the esp-12 development board designed the home automation circuits.

The project was designed by EasyEDA, with easyEDA you can make a Schematic Capture for your documents, Circuit Simulation, Online PCB Designing with the ability of importing PCB and Schematic files, so from this point we can understand that we can create the PCB in this online designer.

Project on their free circuit editor:

- Thu Jan 05, 2017 8:00 am #60463 You need a pull up on GPIO2. You should have more capacitance on the 3.3V line. The series resistor between the 12 volt line and the regulator may cause you issues. And you should have some capacitance on the input of the regulator.

Looking at your layout. You should put a capacitor below the module connected to Vcc and gnd.
