FORLINX-FETA40i-C+121GSE8GEA12

Overview

The Forlinx FETA40i-C is an industrial-grade ARM core board based on the Allwinner A40i quad-core Cortex-A7 processor, operating at a maximum frequency of 1.2 GHz. It integrates a Mali-400MP2 GPU and supports Linux and Android operating systems. The module features extensive connectivity options, including dual Ethernet ports (one Gigabit, one 100 Mbps), Wi-Fi/BT 4.0, and multiple display interfaces such as HDMI, LVDS, MIPI, and RGB, supporting resolutions up to 1920x1080@60fps. It includes two DVP camera interfaces supporting up to 5 megapixels and four TVIN channels for NTSC/PAL video input. The design ensures stability with a wide operating temperature range of -40°C to +85°C.

Procurement Notes

Verify specific configuration variants when ordering, as memory and storage capacities vary. Confirm compatibility with required carrier boards, as the core board utilizes a B-to-B connector interface. Ensure that selected wireless modules (Wi-Fi/4G) match project requirements, as these are often optional add-ons. Check for updated kernel versions if using older software stacks like Linux 3.10.

Selection Notes

Select this core board for applications requiring stable industrial performance with moderate computational power. It is suitable for projects needing multi-screen display capabilities or analog video input processing. Consider the available development resources for Linux and Android when planning software integration. Evaluate the need for additional isolation protection if deploying in harsh electrical environments, potentially utilizing compatible carrier boards like the FCU2401.

Part Context

The FETA40i-C is part of Forlinx Embedded's FET series of industrial core boards, designed to provide long-term supply stability for embedded systems. It leverages the Allwinner A40i platform to offer a cost-effective alternative to commercial chips while maintaining industrial reliability. This product line targets sectors demanding localized supply chains and robust hardware performance over extended lifecycles.

Replacement Considerations

For direct functional replacements within the same manufacturer's portfolio, consider the FETMX6ULL-C for simpler Cortex-A7 applications or the FET3568-C/RK3568 for higher performance needs. Cross-vendor alternatives would require significant hardware redesign due to differences in pinouts and peripheral configurations.
