title: ESP8266 Constantly Restarting
body: <p>I have been struggling for some time now trying to get my ESP8266 ESP-12 to work. I was able to get it loaded with the NodeMCU software. Now, the board constantly restarts itself. Whether I have a script loaded on it or not, the module seems to continually restart. I am using ESPlorer, and can see it get connection to NodeMCU. Then the board restarts several seconds to several mins later. I have tried various pinout, capacitors, etc. with no luck in solving this problem. I have been searching all over and have had no luck finding a solution. Any help is greatly appreciated. Here is my current pinout:</p>
  
  <pre><code>ESP-12          -----------      TTY 3.3v Serial
  ================================================
  TX ----------------------------- RX    
  RX ----------------------------- TX    
  GND, GPIO15 -------------------- GND    
  VCC, CH_PD, GPIO0, (RST) ------- LD1117v33 voltage regulator +3.3v    
  GND, GPIO15 -------------------- LD1117v33 voltage regulator GND
  </code></pre>
  
  <p>Thanks so much in advance for any help!</p>
