FAQ

The Tiny1126B is a highly compact System on Module (SOM) engineered for edge vision and AI applications. The Rockchip RV1126B processor integrates a quad-core Arm Cortex-A53 CPU and a dedicated NPU delivering up to 3 TOPS, enabling efficient acceleration of TensorFlow, PyTorch, Caffe, and MXNet models.
The SOM features a 12MP hardware ISP and an 8MP AI ISP, supporting HDR, 3DNR, fisheye correction, and AI‑adaptive day/night imaging. Advanced capabilities include AOV 3.0 for low‑power audio event detection and 6‑DOF stabilization. The smart encoding engine reduces bitrate by 50%, while hardware security (SM2/SM3/SM4) with TrustZone ensures robust data protection. H.265/H.264 multi‑stream encoding and 4Kp30 decoding are supported.
Ideal for smart surveillance, industrial vision, robotics, and automotive edge AI, the Tiny1126B delivers powerful vision processing in a miniature footprint.
