Powerful Vision & Multi-channel Video Analytics
-40°C to +85°C Stable 24/7 Operation
The FET1126BJ - S SoM supports - 40°C~+85°C operation, delivering excellent reliability and environmental adaptability in complex settings.
LPDDR4 Memory Design for More Scenarios
An LPDDR4 memory design for lower power consumption. DDR4 commercial-grade chips operate at 0°C - 70°C, while LPDDR4 ones cover - 20°C - 85°C.
With RV1126B (- 20°C - 85°C) and eMMC (- 25°C - 85°C)'s wide-temperature features, the commercial-grade SoM works at - 20°C - 85°C, offering low cost and wide-temperature performance.
It combines low cost with wide-temperature characteristics.
Full Software Ecosystem & Rapid AI Deployment
Equipped with the Linux 6.1 OS, it's a major upgrade from the previous - generation RV1126. It offers full BSP support, including kernel source code, file system, drivers, and the RKNN toolchain. It's also compatible with model conversion of mainstream deep - learning frameworks like TensorFlow, PyTorch, Caffe, and MXNet.
RPi 40-Pin GPIO Compatible for Quick Start
The compact development board features 2 x network ports, display, USB and Wi-Fi interfaces, plus pins matching Raspberry Pi 40-Pin GPIO for testing FET1126B-S/FET1126BJ-S SoM functions and AI development.
Compact Development Board with Complete Interfaces
Compact size, measuring only 120mm×75mm, offers interfaces like network ports, 2 x MIPI - CSI, 1 x MIPI - DSI, and 40Pin GPIO (with UART, SPI, IIC).
It can flexibly expand peripherals and sensors, ideal for embedded vision, edge computing, AIoT, and AI inference.
