Core-1126-JD4 High-Performance AI Vision Core Board

Equipped with high-performance quad-core AI vision processor with built-in AI neural network acceleration NPU, the core board has capable computing power up to 2.0 Tops, which can achieve efficient face recognition and detection; it supports multi-channel video coding and decoding and provides various interfaces. It can be flexibly applied to face recognition, gesture recognition, gate access control and other fields.

Quad-core AI vision processor

Low-consumption AI vision processor RV1126, with 14nm lithography process and quad-core 32-bit ARM Cortex-A7 architecture, integrates NEON and FPU — the frequency is up to 1.5GHz. It supports FastBoot, TrustZone technology and multiple crypto engines.

High performance, high computing power

Built-in neural network processor NPU with computing power up to 2.0 Tops realizes that the power consumption of AI computing is less than 10% of the power required by the GPU. With tools and supporting AI algorithms provided, it supports direct conversion and deployment of Tensorflow, PyTorch, Caffe, MxNet, DarkNet, ONNX, etc.

Multi-level image noise reduction

With multi-level image noise reduction, 3F-HDR and other technologies, RV1126 not only ensures the dynamic range of the scene, but also meets the needs of outputting full color in darkness, making "clearly visible" a reality — more conforms to the actual demands in the security field.

4K H.265 encoding & decoding

Built-in Video CODEC supports 4K H.254/H.265@30FPS and multi-channel video encoding and decoding, meeting the needs of low bit rate, low-latency encoding, perceptual encoding and making the video occupancy smaller.

Exquisite and mini

Core board pins are made with gold plating technology, which is anti-corrosion. The size is only 69.6mm x 33.9mm, saving a lot of space.

Stable and reliable OS

It supports Buildroot+QT OS — occupies small space, starts fast, and provides stable and reliable operation.

Various interfaces

SODIMM 260P port is provided; I2C, SPI, UART, ADC, PWM, GPIO, USB2.0, SDIO, I2S, MIPI-DSI, MIPI-CSI, CIF, SDMMC, PHY and other interfaces are equipped, meeting needs of more usage scenarios.

To form high-performance mainboard

The core board can be combined with the backplane to form a complete high-performance industrial mainboard with more expansion interfaces and more powerful performance, which can be directly applied to various smart products to accelerate the product development process.

Abundant resources for customization

A complete SDK, including cross compiler toolchain, BSP source code, application development environment, development documents, examples, face recognition algorithms and other resources, is provided for the users to make a further customization.


It is widely used in face recognition, gesture recognition, gate access control, smart security, smart IP camera, smart doorbell/peephole, self-service terminals, smart finance, smart construction, smart travel and other industries.
