ESP32 Forum

Hi all, this is my first post here. I wanted to share Buce, an open-source aquarium LED controller I developed using the ESP32-C3, and give a technical overview. Some of you might find it interesting for DIY lighting or ESP32 projects.
Buce is a compact controller supporting 6 independent PWM channels, high-resolution dimming, and flexible dimming curves. It’s designed to be modular, reliable, and fully customizable.

Key technical points:

• ESP32-C3 for Wi-Fi connectivity, OTA firmware updates, and remote control.
• Independent PWM channels with 12-bit resolution for smooth lighting.
• Supports multiple dimming curves (linear, logarithmic, exponential, CIE1931) for realistic lighting simulation.
• Fully open-source hardware and firmware (OSHWA certified).
• Built-in over-temperature and over-voltage protection.
• Managed via an Android app (iOS version in development).

All design files and source code are open-source in here: https://github.com/borneo-iot/borneo. If you don't want to join the crowdfunding, you can take the files and manufacture the PCB yourself.

I'd love to hear feedback, ideas, or suggestions from the community. Thanks!

Thank you, where did you get the PCB fabricated from?
