Lindenis V833 is an AI video/camra development board based on Allwinner V833 single-core Cortex-A7 processor with a 400 MOPS AI accelerator (NPU) and running OpenWrt-based Tina Linux or Melis RTOS based on the RT-Thread kernel.
Lindenis V833 specifications:
The board comes with up to 3GB RAM, a MicroSD card socket, MIPI DSI, MIPI CSI, and BT1120 interfaces for video output and input, Gigabit Ethernet, 2.4 GHz WiFi, and a few other I/Os.
SoC – Allwinner V833 single-core Arm Cortex-A7 processor @ up to 1.2 GHz with H.265/H.265 1080p video encoder and decoder, MJPEG 1080p video decoder, 400 MOPS AI accelerator (See PDF datasheet)
System Memory – Up to 3GB DDR3/DDR3L
Storage – MicroSD card slot with support for SDHC and SDXC, SPI NOR flash
4-lane MIPI-DSI up to 1080p
Touch panel header
4-lane MIPI-CSI camera interface
Audio – 3.5mm Line-in jack, built-in microphone
10/100M Ethernet RJ45 port
2.4 GHz WiFi 4 via Allwinner XR819 module
Expansion – 2x 13-pin header with I2C, I2S, PWM, GPIO, GPADC
5V, 1V8, 2V8, and GND
Misc – Buttons for menu, volume, and firmware update, G-sensor (DA380),
12V DC via DC jack
5V/2A via micro USB port
3.7V Li-Ion battery connector
Dimensions – 75 x 68mm
Note that some of the information is not very accurate, notably the memory and storage options are not clear, and it’s better to double-check the information using the schematic and other documents. You’ll also find several repositories on Github.
Lindenis V833 development board
The Wiki provides hardware and software documentation including instructions to get started with Tina Linux (OpenWrt + Linux 4.9) or Melis RTOS based on the RT-Thread kernel. The company recommends Tina Linux as a video SDK is provided with a complete V4L2 framework and open-source applications/demos that include Lindlive low-latency streaming server,
Lindplayer video player, and Lindcamera camera app.
Lindenis V833 block diagram
Allwinner V833 processor is similar to Allwinner V831 we previously reported on, but with a higher CPU clock (1.2 GHz vs 800 MHz), external memory support instead of on-chip DDR2, and a more powerful NPU (400 MOPS vs 200 MOPS). There’s also some reverse-engineering work taking place on Allwinner V831/V833 NPU to develop open-source tools.
Lindenis V833 is the third video/camera board using Allwinner V-series, with the company having previously launched the Lindenis H5 and Lindenis V536 (4K) camera boards, but with different form factors, so there’s no hardware/electrical compatibility between the boards. Lindenis V833 development board can be purchased for $125 on Aliexpress, but again there’s no information about memory capacity and the type of storage soldered to the board.
