Currently, the mainstream AI glasses on the market are generally priced between 400 to 2000 RMB, with the main sales price range being 1000 to 1500 RMB. Qualcomm dominates the mid-to-high-end market with its mature AR/VR ecosystem, while domestic manufacturers such as Spreadtrum and Hengxuan are still seeking breakthroughs in low power consumption and visual processing.
Domestic manufacturer Allwinner Technology today released its latest AI glasses solution, named “Huiyan”. Allwinner Technology also stated that the AI glasses based on the Allwinner V821 “Huiyan” solution have completed their first customer launch and will debut at the Hong Kong Electronics Fair on April 18, officially starting sales.
It is currently unclear what the price range for the V821-based smart glasses solution will be, but a simple search on a certain e-commerce platform shows that the price of the V821 chip is about 20 RMB, which is approximately 3 USD, while the Qualcomm AR1 chip is priced around 60 USD, and the Spreadtrum W517 is about 10 USD. For the cost-effective Allwinner V821 solution, the complete device could even be priced in the range of 200-300 RMB, which indeed shows a strong commitment to pricing.
Let’s take a look at the detailed specifications.
The V821 is a dual RISC-V architecture SoC, with a high-performance ISP and hardware encoding unit integrated, supporting 4MP camera access, ISP processing, and H.264 encoding. The V821 supports single, dual, and triple camera access solutions, and also integrates modules such as Wi-Fi, LDO, IRCUT Driver, and Audio Codec. With excellent ISP processing capabilities, low power consumption, and high expandability, the V821 can be extended to multi-lens network cameras, low-power doorbells, smart locks, and other products.
Advantages of the Allwinner V821 Architecture
The Allwinner V821, with its high integration and miniaturization characteristics, provides customers with flexible and efficient solutions:
- Leveraging the mature industrial chain advantages of Bluetooth chips, the V821 flexibly adapts to various Bluetooth headset solutions, offering more choices in Bluetooth configurations, and can seamlessly expand display functions based on Bluetooth wearable chips;
- During high-definition image/video transmission, the V821’s high-speed bus can directly send HD video and images to mobile phones via built-in Wi-Fi, further saving power to extend battery life;
-
The V821 has built-in low-power memory, allowing for the selection of more cost-effective storage options such as SD NAND, in addition to traditional solutions, further reducing overall costs.
Based on the performance advantages and specifications of the V821 chip, Allwinner has integrated years of experience in image processing technology for action cameras into a product package that meets the architecture of AI glasses, including chip layer, solution layer, and resource layer, facilitating the rapid expansion and implementation of visual wearable products, including AI glasses.
Chip Layer
Big and small core collaboration, millisecond cold start
The fastest 300msto enter photo mode,600msto enter recording mode, meeting the quick capture needs of AI glasses.
Low memory, high pixel, video frame fusionprocessing
Can achieve typical 5MP to 8MP image sensor access and photography under 64MB memory,1080P to 2K video recording,and supports low-latency gyroscope packaging for synchronized frame processing,facilitating mobile side fusion processing.
Low power consumption, long battery life
In typical 1080P 30fps video shooting scenarios, the chip’s average power consumption is283 to 295mW.
Customized ISP, more suitable for AI glasses
For the small image sensors and small apertures typically used in glasses,the ISP is specifically tuned for these characteristics.

Solution Layer
Hardware Reference
For typical AI glasses hardware requirements, Allwinner provides a complete V821 hardware verification reference design and prototype development evaluation board, with reserved interfaces for freely combining backend Bluetooth chips for rapid prototype development and debugging.
Software Applications
For nine typical business scenarios such as photography, video recording, photo and audio/video file storage, file transmission, and AI image recognition, typical scenario firmware can be compiled with one click, enabling rapid integration with Bluetooth chips.Complete Linux application source code will also be provided for secondary development, facilitating the expansion of various differentiated visual wearable products.
Protocol Support
For efficient debugging needs between the SoC and Bluetooth chips, a complete communication protocol has been implemented based on UART/I2S and other interfaces, and RTOS source code is provided for customers to port on the Bluetooth chip side, balancing real-time performance and flexible expansion.Resource LayerCore Peripheral Components
For commonly used materials in AI glasses products such as cameras and storage, adaptations have been completed, including: Geke Micro 5MP image sensor, Sony 8MP image sensor, Hengshuo, and Chip World storage devices. More models are continuously being adapted based on demand.
Algorithm Support Layer
Allwinner not only provides a processing library for basic smartphone anti-shake algorithms but can also assist in integrating third-party anti-shake algorithm libraries, facilitating partners to quickly integrate anti-shake effects based on existing smartphone apps. Future upgrades will include more image and video processing enhancement features.
It is reported that Allwinner’s next-generation V881 series chips, supporting 12MP to 20MP photography and 4K video recording, will debut in the second half of 2025; the V881 chip solution can also seamlessly upgrade on the V821 wearable solution.
