The final two options are the cheapest and the most extensive. If space isn't an issue, I recommend soldering female pin headers to a prototype board and male pin headers to the ESP8266/ESP32.ĪliExpress Buy on Amazon Custom WLED PCBs and direct wiring There are many ways of doing it, and all have their benefits and drawbacks. How exactly you connect the LED strip's data pin to the ESP8266/ESP32 is your decision to make. Using a prototype board and screw terminals A quick Google image search should bring up a schematic, detailing which pin does what. The same goes for a NodeMCU board, but on an ESP32 it is often the pin labelled D4. For example, on a LOLIN (previously WEMOS) D1 mini, GPIO2 is the pin D2. Keep in mind that the GPIO pin does not correspond with the pin's label on the board. Especially the chapter on level shifters should be studied before any wire has been soldered. But before you do that, read through this guide carefully. The data pin on the LED strip connects to GPIO2 of the ESP8266 or ESP32 board. Wiring a basic WLED-powered LED controller is relatively simple, as there is only one way of doing it, though there are a few extra components you might want to add (detailed in the next chapter). Once flashed, you can commence with the wiring. Flashing is then as easy as hitting the “Flash ESP” button. Download the matching binary file for your board from GitHub ( this page has information on which one to choose) and select the binary file in ESPHome flasher, along with the serial port. Once connected, the easiest way of flashing WLED is by using the ESPHome flasher as it has a graphical interface. This way, the board only connects to your computer, there's nothing attached to it by fragile wires, and you don't have to worry about powering any of the other components.ĮSPHome flasher can be used to flash WLED on to an ESP8266/ESP32 I believe that it is easier to first flash the ESP8266 or ESP32 with WLED, before attaching any of the components or soldering a single wire. How to flash WLED on to an ESP8266 or ESP32 Your ESP32 is much better used for complex ESPHome projects, or those that need the power and/or Bluetooth. The ESP8266 can handle powering lamps and accent lighting at ease. Reduce the updates to 15 per second and the ESP8266 can take care of 2048 LED pixels on your strip.Īll in all, it's fair to say that a cheap ESP8266 is the way to go for close to all personal projects. The ESP8266 will handle 1024 individual LED pixels while sending 30 updates per second. Where you will run in to issues is if you are attempting to build a massive project. All WLED does is control addressable LEDs and nothing more. You won't be able to attach any additional sensors that might need the better specs, or use the Bluetooth functionality for presence tracking. Keep in mind that WLED isn't comparable to ESPHome.
