ANAVI Miracle Emitter is a compact, open-source Wi-Fi and Bluetooth development board powered by the ESP32-C3 microcontroller running at 160 MHz with the open standard instruction set RISC-V architecture. It is designed to control an addressable 5 V LED strip such as NeoPixels, which can be powered via the onboard USB Type-C port or externally.

Compatible with popular LEDs like Neopixels, WS2811, WS2812B, and TM1809, Miracle Emitter also features a slot for a mini OLED I²C display, support for up to three additional I²C sensor modules, UART pins, and extra GPIO pins for external peripherals. This makes it ideal for developers, makers, students, and open-source enthusiasts interested in home automation.

Light Up Your World

Fully compatible with Home Assistant and the Arduino ecosystem, ANAVI Miracle Emitter enables developers to easily modify our open-source firmware or flash their own custom firmware. It is also compatible with WLED, a widely used, fast, and feature-rich open-source web server for controlling NeoPixels. It can be used with any programming framework that supports the ESP32-C3. Tech-savvy users can easily incorporate Miracle Emitter into existing open-source ecosystems, enabling them to focus on adding software features and design for specific automation functions.

Use Cases

ANAVI Miracle Emitter is a versatile IoT device suitable for a variety of different use cases:

• Smart Lighting Control: Customize NeoPixel LED effects and brightness with via smartphone or computer over Wi-Fi.
• Climate & Comfort Monitoring: Track temperature and humidity, adjust the lighting to match climate conditions, and receive alerts for any condition that may need your attention.
• Interactive Room Automation: Control lights and devices using motion, gestures, and environmental conditions, integrating with Home Assistant to activate lighting modes upon room entry.
• Mood & Ambiance Control: Set adaptive lighting based on time or weather, create custom scenes for relaxation or work, and sync LED colors with music or seasonal themes.
• Smart Desk Setup: Adjust lighting for productivity or gaming and switch modes with gestures.
• Themed Lighting for Events and Holidays: Create dynamic effects for Halloween, Christmas, New Year's, and other celebrations, triggering festive colors!

Sensors and Peripherals

Out of the box, the default open-source firmware of ANAVI Miracle Emitter supports the following sensors and peripherals:

• 0.96-inch mini OLED I²C display (Included with Starter and Developer Kits)
• BH1750 I²C sensor for light (Included with the Developer Kit)
• BMP180 I²C sensor for temperature and barometric pressure
• APDS-9960 I²C sensor for RGB color, ambient light, proximity, and gesture sensor (Included with the Developer Kit)
• HTU21D I²C sensor for temperature and humidity (Included with the Developer Kit)

You can also attach any other UART or I²C sensor modules, but you’ll need to take care of their software integration.

Comparisons

In 2020, ANAVI Technology successfully crowdfunded ANAVI Miracle Controller, which remains in production and available on Crowd Supply. To tackle new challenges with NeoPixels and other addressable LEDs, we are expanding our lineup of open-source hardware with ANAVI Miracle Emitter.

NOTE: If you are looking to control 12 V non-addressable LED strips, check out ANAVI Light Controller as a standalone device or ANAVI Light pHAT for Raspberry Pi single-board computers.

Support & Documentation

ANAVI Miracle Emitter is a fully open-source project integrating open hardware with free and open-source software. The PCB and acrylic enclosure were designed using KiCad, while the firmware, developed as an Arduino sketch using the FastLED Animation Library, seamlessly integrates with the popular Home Assistant platform via the MQTT protocol.

All source code and schematics are freely available on GitHub. Alternatively, ANAVI Miracle Emitter can be flashed with WLED or other custom firmware. WLED is an open-source firmware for ESP8266 and ESP32 microcontrollers that simplifies control of addressable LED strips with built-in effects, native Home Assistant integration, a user-friendly web interface, and hassle-free installation via a web browser.

Firmware Support

The beauty of open source lies in the freedom to choose what works best for you. With ANAVI Miracle Emitter, an open-source hardware development board, you have the flexibility to easily replace the default firmware with WLED. Below is a side-by-side comparison of key features.

Manufacturing Plan

Reinforcing our commitment to local manufacturing, all units are prepared and packaged in Plovdiv, Bulgaria. To ensure consistently high quality, the PCB (printed circuit board) of ANAVI Miracle Emitter features a black solder mask and a gold surface finish. At its core is the Seeed Studio XIAO ESP32C3, a compact IoT module built on the cutting-edge open RISC-V architecture. Each unit is meticulously flashed and tested with our open-source firmware developed as an Arduino sketch.

Fulfillment & Logistics

All ANAVI Miracle Emitter kits will be shipped to our backers using Crowd Supply’s fulfillment services.

Once manufacturing is complete, we’ll make a bulk shipment to Crowd Supply, and from there, the packages will be shipped out to our backers. For more details, please refer to the Crowd Supply guide to ordering, paying, and shipping.

We are committed to sustainability, so all units are packaged inside eco-friendly, recyclable cardboard boxes.

Risks & Challenges

We have already successfully manufactured and assembled a small batch of ANAVI Miracle Emitter printed circuit boards and acrylic enclosures to verify functionality and confirm readiness for mass production!

We have a proven track record of delivering projects on time, and often ahead of schedule, as demonstrated by our previous crowdfunding campaigns. Our journey began in 2017 with the ANAVI Infrared pHAT add-on board for Raspberry Pi, and most recently, we successfully delivered the ANAVI Dev Mic USB-C computer microphone with Raspberry Pi RP2040 microcontroller. Over the years, we have built a trusted supply chain by partnering with small local factories in Plovdiv and the surrounding regions. We maintain stock of all components to minimize manufacturing risks and guarantee timely delivery.
