1PCS Great IT ESP8266 ESP-01 ESP-01S RGB LED Controller Module for Arduino IDE WS2812 Light Ring Smart Electronic DIY
 
Instructions download: https://github.com/IOT-MCU.
This is a WS2812 RGB LED control module based on ESP-01 / 01S. With it, you can easily control the WS2812 light bar / light ring. DIY own lightin s g control system. Support for Ard uino IDE programming.
 
、
Characteristic:
 
* Master: ESP-01 / ESP-01S
* Control Pin: GPIO2
* Interface: 3Pin PH2.0 connector
* Operating Voltage: DC 3.7V-5V (Please note: The positive supply voltage VCC on the board is connected to the VCC on the WS2812 3PIN connector. Therefore, if your light bar / lamp ring is 5V powered, use DC 3.7V-5V power supply.)
* Support 3.7V lithium battery
