Relay Module:

WS2812 RGB:

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 lighting control system. Support Ard uino IDE programming.

characteristic:

* Master: ESP-01 / ESP-01S (This module does not include 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
