@@ -72,7 +72,7 @@ To do the testing I have collected the following hardware:
 - **ESP8266 module** - NodeMCU 1.0 (ESP-12E Module). I have selected this one to make my prototyping more convenient. It has USB / serial interface and power supply on board, so you do not need to provide them separately. You can use any other [typical ESP8266 modules](https://github.com/esp8266/Arduino/blob/master/doc/boards.md#table-of-contents) as well. One single pin GPIO3 (TXD0) is used for driving WS2812B and make sure it is broken out in your module.
 - **Pixel strip power supply** - Adjustable DC-DC power supply CN4015-3.1 together with AC-DC 12V power supply. You should be able to go away with a "wall wart" 5V DC power supply assuming it will match power consumption of your LED strip. To avoid potential issues with 3.3V logic of ESP8266, use an adjustable power supply and lover output voltage below 5V. For more details please check excellent guide ["Powering NeoPixels"](https://learn.adafruit.com/adafruit-neopixel-uberguide/power) by Adafruit.
 - **1000uF/16V capacitor** to improve quality of power supply to the pixel strip - see ["Best Practices"](https://learn.adafruit.com/adafruit-neopixel-uberguide/basic-connections) by Adafruit.
-- **470Ω resistor** to separate ESP8266 and the pixel strip. For more details please check ["Best Practices"](https://learn.adafruit.com/adafruit-neopixel-uberguide/basic-connections) by Adafruit.
