RV1126B AI Vision Board with 3 TOPS NPU – EPI_1B

Product Description

The EPI_1B RV1126B AI Vision Board is a compact Linux-based embedded AI computing platform designed for intelligent vision, smart camera, robotics, security, and edge AI applications.

Powered by the Rockchip RV1126B quad-core 64-bit ARM Cortex-A53 processor, the board integrates a dedicated 3 TOPS NPU supporting INT8/INT16 mixed-precision AI computing. This enables local AI inference for applications such as object detection, face recognition, image classification, human detection, and other computer vision workloads.

The board provides two 4-lane MIPI-CSI camera interfaces for multi-camera, binocular, and stereo vision applications. A 4-lane MIPI-DSI interface supports displays up to 1920 × 1080 @ 60 fps. The platform also supports 4K H.264/H.265 video encoding and 4K H.264 decoding.

With a compact 85 × 56 mm board size, Linux support, 40-pin expansion header, USB, Ethernet, Wi-Fi, Bluetooth, audio, and multiple storage options, the EPI_1B is well suited for OEM and ODM developers integrating AI vision capabilities into commercial and industrial products.
