Allwinner V861 is a new dual-core 32-bit/64-bit RISC-V C907 system-in-package (SiP) with 128MB on-chip DDR3L designed for 4K AI camera applications with 1 TOPS AI NPU.
The chip also features a 32-bit RISC-V E907 low-power core, a 4Kp25 H.264/H.265 video encoder, a 1080p60 JPEG video decoder and encoder, MIPI CSI and parallel camera interfaces, an audio codec with input/output interfaces, Fast Ethernet, USB 2.0, and a set of digital and analog I/O.

All winners mention: The V861 series has several variations with slightly different specifications. The above specs are for the V861M3-XXX model, and I'm told to refer to the official datasheet for other variants, but since the documentation isn't publicly available, there's nothing I can do about it.
The company also highlights support for up to three camera inputs, suitability for solar-powered cameras, and millisecond-level startup times for AI-ISP. Allwinner V861 can be used for IP cameras, 4G LTE HD cameras, smart doorbells, and AOV (Always-on Video) solutions.
The Allwinner V861 is not the company's first RISC-V camera SoC. The company previously announced the V821 32-bit RISC-V with support for WiFi and a Full HD camera. The new processor features two 64-bit RISC-V cores, supports 4K resolution, H.265 video codec, and integrates 1 TOPS AI accelerator. Like its predecessor, it is officially supported by the company's Tina Linux SDK, which is based on OpenWrt.
I learned about this new SoC through a post on X by Yuzuki Hyun (GLGH_), who designed the successor to the Avaota F1 camera board (aptly named Avaota F2). It is equipped with the Allwinner V861M3-XXX SiP and features a USB-C port, dual camera support, PTZ motor controller via AXP333 PMIC, microSD card slot, connectors for microphone and speaker, as well as I/O via through holes and castellated holes.
This board, like its predecessor, will be open source hardware, but the files are not yet publicly available. I'll be sure to write more about it once the details are published and the board is available for sale.
