Forlinx’s FET1126Bx-S is described as a compact industrial system-on-module designed for low-power edge AI and embedded vision applications. The 40 mm × 40 mm module targets systems such as intelligent video analysis, smart infrastructure, and industrial monitoring, where local inference and long-term availability are required.

The FET1126Bx-S is based on the Rockchip RV1126 B or RV1126BJ processor, integrating four Arm Cortex-A53 CPU cores. Datasheet information indicates that commercial variants operate at up to 1.6 GHz, while industrial-grade versions are clocked at up to 1.3 GHz. An on-chip NPU provides up to 3 TOPS of INT8 performance, enabling AI inference workloads to run locally without reliance on cloud connectivity.

Memory configurations include 1 GB, 2 GB, or 4 GB of LPDDR4. Storage is provided via on-module eMMC, with commercial versions paired with 64 GB eMMC, while industrial variants are available with 8 GB, 16 GB, or 32 GB options depending on configuration.

According to Forlinx, the module is designed primarily for vision-centric workloads. It supports hardware decoding of H.264 and H.265 video streams up to 4K resolution, along with hardware encoding for H.264, H.265, and JPEG. The integrated ISP and AI-ISP provide support for features such as HDR, noise reduction, fisheye correction, and image enhancement.

Camera connectivity includes support for up to two MIPI-CSI interfaces using MIPI D-PHY v1.2, as well as a parallel DVP interface compatible with BT.601, BT.656, and BT.1120 standards.

Display output is limited to a single channel and can be routed through MIPI-DSI, BT.656/BT.1120, or a 24-bit RGB interface, with a maximum supported resolution of 1920 × 1080 at 60 fps.

FET1126Bx-S Features

Despite its small footprint, the FET1126Bx-S exposes all functional processor pins through a combination of stamp-hole and LGA connections, totaling 237 pins.

Available interfaces include Gigabit Ethernet via RGMII, an integrated 100 Mbps Ethernet PHY option, USB 2.0 and USB 3.0 dual-role support, multiple UARTs, CAN, SPI, I²C, PWM, ADC channels, audio interfaces, and general-purpose GPIOs..

For development and evaluation, Forlinx provides the OK1126Bx-S carrier board. The board exposes interfaces such as Ethernet, USB, dual MIPI-CSI connectors, display outputs, audio, and a Raspberry Pi–compatible 40-pin header, allowing developers to evaluate AI and vision workloads without designing custom hardware at an early stage.

On the software side, the FET1126Bx-S supports Linux 6.1, with flashing via USB OTG or MicroSD card. Forlinx notes that its software package includes kernel source code, drivers, development tools, sample applications, and AI algorithm examples. The platform also supports Rockchip’s RKNN toolchain for deploying models from frameworks such as TensorFlow and PyTorch.
