In the fields of industrial automation, intelligent terminals, and IoT gateways, a stable, feature-rich, and cost-effective embedded core platform is key to product success. Chengdu EBYTE Electronic Technology Co., Ltd.'s ECK31-T13SA series, built on the domestic Allwinner T113-S processor, is a mature industrial-grade solution ranging from core boards to complete single-board computers. This article will deeply analyze the product matrix, technical features, and provide a clear selection guide.

ECK31-T13SA Series Core Boards Overview

The ECK31-T13SA series is a well-structured, flexible product family designed to meet needs at different stages, from underlying hardware development to rapid product prototyping.

Core Layer: ECK31-T13SA Series Core Boards
This is the "brain" of the entire system, using 8-layer board immersion gold technology with dimensions of only 35mm × 29mm × 3mm. All functions are accessed through 116 stamp hole pins. It integrates the Allwinner T113-S processor, memory, storage, Gigabit Ethernet PHY, power management, and clock circuits, with all components being domestic industrial-grade (-25°C ~ +85°C).

The series offers four main models, differentiated by three dimensions: "processor performance - memory capacity - storage type":

Advantages of Core Boards:

• Full Localization: Key components such as processors, memory, and storage are all domestically produced, ensuring supply chain security and controllability.

• Full Interface Access: 116 pins provide access to almost all processor resources, including RGB/LVDS/MIPI display, CVBS video input/output, Gigabit Ethernet, USB 2.0, multiple UARTs, I2C, SPI, CAN, PWM, and ADC.

• Single Power Supply: Only requires +5V power input, with on-board efficient power management to simplify baseboard design.

• Industrial-Grade Design: Lead-free immersion gold technology, wide-temperature operation, and high reliability.

System Layer: ECB31-P4T13SA2ME8G Single-Board Computer
This is a complete evaluation and mass production platform developed based on the flagship ECK31-T13SA2ME8G core board, allowing users to directly verify and develop without designing a baseboard.

Core Functions and Interfaces 

• Computing Core: Equipped with the ECK31-T13SA2ME8G core board (dual-core A7 @ 1.2GHz + RISC-V + HiFi4 DSP, 256MB RAM, 8GB eMMC).

• Rich Peripherals:

• Display: 1-channel 4-lane MIPI DSI interface (supports 1080P@60fps touchscreen), 1-channel CVBS output, 1-channel CVBS input.

• Networking: 1-channel 10/100/1000M adaptive RJ45 Ethernet port, 1-channel 2.4G/5G Wi-Fi (on-board module).

• Connectivity: 3-channel USB 2.0 HOST, 1-channel USB OTG Type-C, 1-channel debug UART Type-C.

• Expansion: 1 TF card slot, 1 3.5mm audio interface (headphone + microphone), 2-channel CAN, multiple GPIO/UART/I2C accessed through Raspberry Pi-compatible 40Pin headers.

• Other: Reset button, RTC battery holder, power/run/debug indicators.

• Power and Structure: 12V DC input, form factor compatible with Raspberry Pi, suitable for direct use in industrial scenarios.

Core Value of the Single-Board Computer:

• Zero Hardware Startup: Provides an out-of-the-box complete hardware platform, greatly shortening the product pre-verification cycle.

• Gold Standard Reference Design: Its baseboard design is an excellent reference for core board applications, with schematics, PCB, BOM, and other materials open to users, significantly reducing the design risk and cycle of self-developed baseboards.

• Complete Software Ecosystem: Pre-installed with a Linux 5.4-based system, and provides complete U-Boot, kernel, Buildroot source code, and cross-compilation toolchain, with a mature software development environment.

Analysis of the Allwinner T113-S Processor

The series' strong foundation stems from the heterogeneous multi-core architecture of the Allwinner T113-S processor:

• Dual-core ARM Cortex-A7 @ 1.2GHz: Runs mainstream Linux systems and upper-layer complex applications.

• RISC-V Core: Handles real-time tasks or performs co-processing.

• HiFi4 DSP @ 1.2GHz: Optimized for audio algorithms, supporting advanced audio processing.

• Integrated Video Engine: Supports H.265/H.264 decoding and integrates a graphics processing unit.

This design achieves an excellent balance between multimedia processing, real-time control, and general computing, making it ideal for edge devices requiring interactive interfaces, network connectivity, and local intelligence.

Selection and Application Scenario Guide

How to Choose a Core Board?
