Entry-level: Cortex-A7, Cost-effective Entry Point for Linux Embedded Systems

For numerous industrial control, Human-Machine Interface (HMI) and IoT gateway applications, traditional MCUs such as STM32F4/H7 series can no longer meet the requirements of running Linux systems, processing complex network protocols, or driving graphical interfaces. At this point, core boards based on single-core or dual-core ARM Cortex-A7 processors become the ideal upgrade solution.

Technical Characteristics

1. Architecture: ARM Cortex-A7, with typical clock frequency ranging from 650MHz to 1GHz

2. Positioning: Provides basic computing power for running embedded Linux operating systems such as Buildroot, supports lightweight GUI including LVGL and QT, and handles multi-channel serial ports, CAN bus and Ethernet communication.

Representative Models

1.1 STM32MP1 Series: EBYTE ECK10-13xA Series

This series adopts STM32MP135 processor with 650MHz clock frequency, equipped with 512MB DDR3L and 512MB NAND Flash. It integrates Gigabit Ethernet PHY on board, allowing users to obtain network functionality by simply connecting a transformer, greatly simplifying baseboard design. The industrial temperature range from -40℃ to +85℃ ensures stability in harsh environments.

1.2 NXP i.MX6ULL Series: EBYTE ECK20-6Y28C Series

This series adopts i.MX6ULL processor with up to 792MHz clock frequency, providing eMMC or NAND Flash storage options. It leads out 120Pin pins through BTB connector, with rich industrial interfaces including 8 UART channels and 2 CAN channels, making it a highly cost-effective industrial control core board.

Key Model Specifications Comparison

Application Scenarios

Industrial controllers, serial servers, building automation gateways, basic HMI panels.

Mid-range Mainstream: Cortex-A55, Versatile Platform for Multi-task Processing and Graphical Interfaces

When application scenarios require running multiple complex tasks simultaneously, supporting smoother graphical interfaces, or processing higher-speed data streams, entry-level single-core Cortex-A7 becomes inadequate. At this point, processors equipped with dual-core or even quad-core Cortex-A55 become the mainstream choice in the market.

Technical Characteristics

1. Architecture: ARM Cortex-A55 (multi-core), with typical clock frequency ranging from 1.0GHz to 1.5GHz

2. Positioning: Provides significantly improved multi-task processing capability and graphics rendering performance, capable of smoothly running Android or more complex Linux desktop environments. Suitable for devices with higher requirements for user interaction experience and data processing capability.

Representative Models

2.1 Allwinner T113-i Series: EBYTE ECK30-T13I Series

This is a domestic dual-core Cortex-A7 processor (with RISC-V coprocessor in some cores) with 1.2GHz clock frequency. It features full domestic supply chain and high cost-effectiveness, having strong competitiveness in entry-level HMI and basic gateway fields.

2.2 Rockchip RK3506 Series: EBYTE ECK41-E Series

Adopting Cortex-A35 processor (equivalent or alternative architecture to A55) with 1.5GHz clock frequency, it has extremely small size of only 29x25mm and ultra-low power consumption, specially designed for space-constrained embedded devices such as portable medical equipment or micro controllers.

Application Scenarios

Mid-to-high end HMI, smart home central control panels, industrial tablets, entry-level edge computing nodes.

High-end Flagship: NPU Integration, Leaping from "Connectivity" to "Intelligence"

As AI technology sinks to the edge side, industrial equipment no longer satisfies with simple "connectivity" and "control", but requires real-time perception, analysis and decision-making capabilities. For example, real-time product defect detection on production lines, or face recognition in industrial parks. This requires core boards not only to have strong CPU computing power, but also integrate dedicated AI acceleration engine - NPU (Neural Processing Unit).

Technical Characteristics

1. Architecture: Multi-core ARM Cortex-A55 + Neural Processing Unit (NPU)

2. Positioning: Specially designed for edge AI application scenarios, capable of running deep learning models with extremely low power consumption and high efficiency, implementing tasks including object detection, image classification, and speech recognition. It serves as the computing core for smart factories, unmanned retail, intelligent security and other fields.

Pyramid Selection Guide: Three Steps to Find Your Optimal Core Board

Facing numerous choices from entry-level to flagship models, how to quickly lock the most suitable core board for your project? It is recommended to follow the path below:

1. Evaluate computing power requirements

1. Only need to run Linux, control peripherals, and process network protocols: Choose entry-level models (Cortex-A7)

2. Need smooth graphical interface, complex multi-task processing or running simple local algorithms: Choose mid-range mainstream models (multi-core Cortex-A55)

3. Need to run AI models in real time for image/video analysis: Choose high-end flagship models with NPU

2. Verify core count and clock frequency
After determining the architecture, choose dual-core, quad-core or eight-core according to task parallelism. Higher clock frequency leads to faster single-thread task processing speed. Generally, mid-to-high end applications recommend clock frequency no lower than 1.0GHz.

3. Confirm AI accelerator performance
If AI functionality is required, NPU computing power measured in TOPS is the key indicator. Simple voice keyword wake-up may only require 0.1 TOPS, while complex real-time video analysis requires more than 1 TOPS. Select products with appropriate NPU computing power according to algorithm complexity and real-time requirements.

In summary, the industrial core board product line has formed a clear "pyramid" structure. From cost-effective entry platforms based on Cortex-A7 to high-performance flagships implementing AI inference, each level accurately corresponds to specific performance requirements and cost budgets. Understanding this "computing power evolution theory" will help you make the wisest decision in project selection, and help your products achieve accurate positioning in the wave of intelligence.
