1 Breathing Light Driver

The Thunderbird AI Camera Glasses V3 is equipped with Awinic's high-performance 3-channel breathing light driver. It can not only realize functions such as charging status indication and overall device working status indication but also has a flexible breathing light that can present various light effects in conjunction with different voice interaction commands of the user, bringing users a rich and unique visual experience.

Features of 3-Channel Breathing Light Driver

3 independent high-precision current sources, capable of driving 3-channel monochromatic lights or 1 RGB light
4-level global current regulation, with a global current adjustment range of 5-30mA
256-level PWM dimming for each independent channel
16-level DC dimming for each independent channel, with a total of 4096-level color mixing adjustment for 3 channels
Flexible light effect configuration and autonomous breathing mode, saving main control power consumption and MCU resources
Some models can directly drive the LED1 channel for autonomous breathing under low battery conditions without software configuration, which can be used as a charging indicator when the battery is low
Communication interface: 400kHz I2C, compatible with 1.8V~3.3V levels
LED channel current accuracy ±3%, channel matching accuracy ±3%
Power supply range: 2.5V~5.5V
Some models can collect audio signals for autonomous music rhythm

2 DSP Digital Audio Power Amplifier

For AI smart glasses, the human-computer interaction mode of voice interaction is crucial. On the basis of conventional voice assistant dialogue functions, combined with AI large models, more functions can be realized in more scenarios. As functions increase, the requirements for the audio link are also increasing. Awinic's high-performance DSP digital audio power amplifier drives a 9mm*20mm super-large sound unit, bringing an excellent audio-visual experience, helping AI voice interaction to be more excellent, and improving the intelligent interaction level of the product.
