Banana Pi BPI-M6 is a credit-card single board computer based on SenaryTech SN3680 SoC comprised of a quad-core Arm Cortex-A73 processor, an Arm Cortex-M3 real-time core, an Imagination GE9920 GPU, and an NPU delivering up to 6.75 TOPS.
The board ships with 4GB LPDDR4 RAM and 16GB eMMC flash. Its layout is fairly similar to the one of the Raspberry Pi 4 with four USB ports, Gigabit Ethernet, a 40-pin GPIO header, a USB Type-C port for power, and two micro HDMI ports. However, only one of those is for HDMI output, as the second is for HDMI input, and there’s also an M.2 Key-E socket for expansion.

Banana Pi provides Android and Ubuntu 20.04 images for the board which you’ll find in the wiki along with hardware documentation, a Linux SDK with Kernel 5.4 and Buildroot 2019.10, the config file for the Armbian build system, and instructions to use the SenarySocSystemTool flashing tool.
The VideoSmart VS680 is shown to score 29.90 points in the AI benchmark rankings for IoT processors which shows the NPU is a Vivante VIP9000. It has a higher score than the Amlogic A311D (21.9) and Rockchip RK3566 (14.1), but not quite as good as the better-supported Rockchip RK3588S (95.7) with a (slower in theory) 6 TOPS AI accelerator. For reference, the MediaTek Genio 1200 processor comes in third with 151 points in that list, only outperformed by Qualcomm Snapdragon SA8295P (161) and Mediatek MT8195 (Kompanio 1200) with 165 points.
Banana Pi shared some demo videos showing the AI capabilities of the board, but I was unable to find documentation and resources to make use of the Vivante VIP9000 NPU in the VS680 SoC. Synaptics mentions support for the Synap AI framework, but the company is not exactly known for releasing development tools publicly. Note that the Vivante NPU in the Amlogic A331D SoC recently got Etnaviv open-source driver support, so the VS680 may end up being supported as well, although that will likely depend on the developer community interest rather than Banana Pi working on it…
