Bright and Responsive
The colors are vibrant and the Wi-Fi connectivity allows me to control the lighting from my phone. Setup took about 10 minutes. Highly recommend for anyone into DIY ambient lighting.

Great learning tool
Bought this for a university IoT project. The ESP32 is powerful and the RGB ring adds a nice visual element to data visualization. Documentation could be slightly more detailed, but the code examples work well.

Easy to start with
As someone new to embedded systems, this was a friendly entry point. The Arduino library support is excellent. Only wish it came with a small case to protect the components.

Perfect for PC Case Mods
This board is exactly what I needed for my custom esports rig. The circular ring light looks fantastic behind the motherboard tray, and the included code made it easy to sync with my system temps.

Exceeded Expectations
Using this to create reactive lighting based on in-game audio. The processing power of the ESP32 handles the FFT analysis without lag. A must-have for serious modders.

Solid Hardware
Good build quality on the PCB. The WS2812B LEDs are evenly spaced and bright. I appreciate that they included the source code repository link right on the packaging.
Q: Are there extra GPIO pins available for sensors?
A: Yes, the board breaks out several GPIO pins along the edge, allowing you to connect additional sensors like temperature or motion detectors to expand your project.
Q: Does this support Home Assistant integration?
A: Yes, since it uses the ESP32 chip, you can flash ESPHome firmware onto it to seamlessly integrate the lighting into your Home Assistant dashboard.
Q: Is the source code compatible with the Arduino IDE?
A: Yes, the provided source code is fully compatible with the Arduino IDE. You will need to install the ESP32 board manager package and the Adafruit NeoPixel library.
Q: What is the maximum brightness level of the ring?
A: The WS2812B LEDs can reach high brightness levels suitable for ambient lighting. However, brightness is software-controllable, allowing you to dim them to save power or reduce glare.
Q: Can I power this directly from a USB port on my PC?
A: Absolutely. The board features a Micro-USB port that provides sufficient 5V power to run both the ESP32 microcontroller and the 12-LED ring simultaneously.
