LaskaKit ESPwled

Product detailed description

LaskaKit ESPwled is a development board with an ESP32-C3 chip designed for the open-source WLED project, allowing you to control addressable LED strips via Wi-Fi without the need for programming. You can easily flash the WLED firmware to the board using the project's web browser, and then control the strips from a browser on your phone, tablet, or computer. The board supports 5V, 12V and 24V LED strips, compatible with single-wire (WS2812B, SK6812…) and dual-wire strips with a clock signal (APA102), and also features μSup connectors for I2C and SPI, allowing you to connect sensors and other peripherals.

How to upload WLED:

• Connect the board to your computer via a USB-C cable.
• Switch the ESP32-C3 to flashing mode: press and hold the FLASH button, press and release the RESET button, and then release the FLASH button.
• In the WLED project browser, select the connected LaskaKit ESPwled board and upload the program.
• Connect (e.g. via smartphone) to the Wi-Fi AP created by ESPwled and enter the name and password of your Wi-Fi network.
• ESPwled will then connect to your Wi-Fi, allowing you to control the connected LED strips via a browser on your phone, computer, or tablet.
• Important: The data pin for the LED strip is GPIO 5, not GPIO 2 as set in the WLED default settings – therefore, the pin must be changed in the WLED settings (via the web browser). If the LED strip also has a CLK signal, it is connected to GPIO 4.
