OEM ODM Smart Home Automation Led Light RGBW Control Module Alexa WiFi Dimmer Module
What is the smart wifi module for led light ?
GWF-KM50 module is specifically designed for LED driver application purpose, a most popular IOT application 2.4GHz WiFi chipset (ESP8266EX, made by Espressif) is adopted.
For normal application, this module comes with a set of reference hardware design and generic APP software which should help the downstream LED driver developer or manufacturer to realize customized LED driver design easily.
If customized and deeper design is requested, There are some demo APIs, the software SDK information of ESP8266EX can be easily found on Internet or on the Espressif website (https://www.espressif.com/en/home), this document is described subject the developers or engineers have already known the ESP8266EX development environment.
What is the Main Features of KM49 ?
Module:
l2.4GHz IEEE 802.11 b/g/n WiFi
l4 PWM outputs, applicable for brightness and color temperature control for White(or Warm); Cool white+Warm white; R+B+G; R+B+G+White 4 different modes application.
lSupport ordinary wall power switch reset or User-define scenes control.
lSupport FOTA (Firmware over the air) wireless firmware upgrade.
lPCB pads Dip-through soldering compact design to limit application space.
lOn board antenna (External antenna is available upon request).
APP:
The module comes with functional APP software to realize following functions:
lSupport smart config paring to quick connect WiFi network.
lBrightness, color/color temperature, lighting effects control, ready for different LEDs combination application.
lSupport within WLAN local control and over Internet remote control.
lSupport Alexa/Google Home/Tmall Genie/DuerOS voice control.
lSupport LAN connected devices share and cloud connect devices share.
lSupport devices interaction and combination control.
lSupport Android and iOS system.
lThe comprehensive APP can also be extended to control other devices rather than LED lights only.
