Production-grade open-source stack for aquarium LED dimmers. Hardware designs, embedded firmware, and mobile controls. Ready for weekend builds or product integration.
This project delivers a full-stack solution for smart aquarium LED:
- Hardware: Certified open-source PCB designs targeting the ESP32 family, featuring 6-channel PWM dimming and modular architecture.
- Firmware: A robust ESP-IDF based firmware implementing CoAP/CBOR protocols, sunrise/sunset simulation, and cooling control.
- Mobile App: A cross-platform Flutter application for intuitive real-time control, scheduling, and device management.
New users: Follow the step-by-step guide to flash firmware and connect your first device.
No toolchain required, flash directly from Chrome/Edge Browser:
- Connect ESP32/ESP32-C3/ESP32-C5 via USB
- Visit flasher.borneoiot.com
- Download the app and power on
- 6 or 10 PWM channels, 12-bit resolution (4096 steps), up to 19kHz
- Flicker-free, suitable for aquarium photography
- 22×30mm core module, fits slim LED fixtures
- ESP32-C3/C5 native, WiFi + Bluetooth LE
- Sunrise/sunset curves with millisecond-smooth transitions
- SNTP time sync: automatic, no manual adjustment
- Active cooling control: temperature-based fan/PWM throttling
- OTA updates: over-the-air firmware upgrades
- CoAP + CBOR protocol: efficient, low-latency device communication
- Cross-platform: iOS, Android, Windows, built with Flutter
- Real-time control: dimming, scheduling, scene presets
- Multi-device: group control, cloud-free local network
- Developer API: Python client for automation
