The controller is designed to have extra small size (22x26x14mm), and costs under $2 per item. Four independent channels allow to create lamps with different blink effects or control RGB led strip.
Based on ESP8266-01 microcontroller
Repository store firmware for WiFi controlled LED lamp
Works with homeassistant
Supports effects
Allows to dim light
Dimming based on PWM
May work as a WiFi switch
| Design | Description |
|---|---|
| Light SOT32 | Uses SOT32 MOSFET's mounted under voltage regultar. |
| Light SOT32 bottom | Uses SOT32 MOSFET's mounted on the other side of the board. |
| Light TO-220 | Uses TO220 MOSFET's for long led strips that requere high power. |
| Panelized | Contains all 3 kind of boards replicated 4 times. Archive contains all necessary files for a manufacterer. Board size does not exceed 100X100mm. It is the smalles and cheappes size. Could be ordered from jlcpcb.com for $2. |
Light SOT32 and Light SOT32 bottom are low power versions of the board. It can handle up to 2A per chanel. When Light TO-220 is a high power board with up to 15A per channel.
