Introduction

In embedded industrial computing product selection, engineers often face a common challenge: when confronted with a model number like "ECK10-131A2M2M-I" or "ECK20-6Y28C5E8-I", how can you quickly determine its processor, memory, storage, and operating temperature range? Without the ability to extract key configuration information directly from the model number, you'd have to flip through product manuals page by page — inefficient and error-prone.

EBYTE has designed a rigorous numbering system for its industrial computing product line (core boards, single board computers, and industrial controllers). Once you master this "decoder ring," you can grasp the core configuration of any product in seconds just by looking at its model number, enabling you to quickly identify the best fit for your project. This article takes you deep into the numbering rules, unlocking the secrets behind "ECK10-131A2M2M-I."

Product Overview

EBYTE industrial computing product model numbers follow a three-segment structure: "Prefix + Core Identifier + Suffix." Each segment carries specific product information. Different product types (core boards, single board computers, industrial controllers) have different prefixes, but the internal encoding logic remains consistent.

Product Prefix System

Key Advantage: Core boards, single board computers, and industrial controllers share the same numbering logic — learn one and you can apply it across the board.

User Needs Addressed

• Rapid Selection: Engineers can identify processor architecture, memory capacity, storage type, and temperature grade at a glance without browsing through manuals.

• Error Prevention: Procurement and engineering teams can accurately verify materials via the model number, avoiding development delays caused by configuration mismatches.

• Flexible Parameter Management: For customized projects, the numbering rules allow clear description of custom parameters without ambiguity.

Core Board Decoding Examples

Example 1: ECK10-131A2M2M-I

One-line description: An industrial-grade stamp hole core board based on the STM32MP131 processor with 256MB DDR3L memory and 256MB NAND Flash storage.

Example 2: ECK20-6Y28C5E8-I

One-line description: An industrial-grade BTB connector core board based on the NXP i.MX6ULL processor (792MHz) with 512MB DDR3L memory and 8GB eMMC storage.

Example 3: ECK10-135A5M5M-I

One-line description: An industrial-grade stamp hole core board based on the STM32MP135 processor with 512MB DDR3L memory and 512MB NAND Flash storage.

Single Board Computer & Industrial Controller Numbering Rules

Single board computers and industrial controllers follow the same logic as core boards, with slight extensions in prefix and structure.

SBC Example: ECB20-6Y28A5ME8G-I

Industrial Controller Example: ECM31-B08

Industrial Controller Example: ECM33-A06

 Application Scenarios: Practical Value of the Numbering Rules

Scenario 1: Rapid Project Fit Assessment

When you see a model like "ECK30-T13IA5ME8G-I", you can quickly determine:

• Allwinner T113-i processor core board (ECK30)

• 140-pin stamp hole package (A)

• 512MB DDR3 memory (5M)

• 8GB eMMC storage (E8G)

• Industrial temperature range -40°C ~ 85°C (I)

Comparison: Compared to the i.MX6ULL-based "ECK20-6Y28C5E8-I," the T113-i features a dual-core Cortex-A7 + RISC-V + DSP heterogeneous architecture with stronger computing capability, while the i.MX6ULL offers a more mature ecosystem and supports 3.3V/5V wide voltage input.

Scenario 2: Multi-Solution Rapid Screening

During project selection, you can quickly filter by model number:

• All models containing "I" → Industrial temperature grade

• All models containing "E8" → 8GB eMMC large storage

• All models containing "C" → BTB connector for easy maintenance and upgrade

• All models containing "A" → Stamp hole soldering for higher reliability in vibration environments

FAQ (Frequently Asked Questions)

Q1: What are the practical differences between package type letters in production?

A: Significant differences exist:

• A (Stamp Hole): Soldered via SMT, high connection reliability, suitable for vibration environments and harsh conditions. Difficult to replace once soldered.

• C (BTB Connector): Plugs into baseboard via BTB connector, convenient for core board upgrades, debugging, and maintenance. Connector mating cycles are limited (typically 500+ times), and less stable than stamp hole in strong vibration environments.

• D (Gold Finger): Plugs into baseboard via DDR3 gold finger, reliable contact, suitable for scenarios requiring frequent plugging/unplugging, but slightly higher cost.

Q2: How should temperature grade identifiers be understood?

A:

• C (Commercial): 0°C ~ 70°C, suitable for indoor, office environments, and consumer products. Lowest cost.

• I (Industrial): -40°C ~ 85°C, suitable for outdoor, industrial sites, automotive electronics, and other harsh environments. EBYTE's mainstream option for core boards.

• N (Extended): -25°C ~ 85°C, between commercial and industrial grades, commonly found in fully domestic-component solutions.

Q3: What is the difference between memory capacity "2" and "2M"?

A: These must be understood in the context of the product series:

• In the ECK10 series, "2" represents 256MB DDR3L memory.

• In the ECK31 series, "2M" represents 256MB SiP DDR3 memory.

• In the ECK32 series, "2" represents 2GB LPDDR4 memory.

Core Principle: The same digit may represent different capacities across different core board series. Always interpret it together with the product series prefix. The most accurate information comes from the configuration table in the corresponding product manual.

Q4: How can I tell from the model number whether the core board uses NAND Flash or eMMC storage?

A:

• Storage field starting with "N" → NAND Flash (e.g., N5 = 512MB NAND, N2 = 256MB NAND)

• Storage field starting with "E" → eMMC storage (e.g., E8 = 8GB eMMC, E16 = 16GB eMMC, E32 = 32GB eMMC)

• No storage field → Some models (e.g., ECK10-135D2-C) have no eMMC marking, indicating no onboard mass storage or only a small amount of SPI NAND.

Q5: Are the numbering rules for single board computers and core boards exactly the same?

A: Highly consistent, but not identical. The core portion of the SBC (ECB series) model number (processor, package, memory, storage, temperature) is exactly the same as the corresponding core board. However, the SBC model number is slightly longer, e.g., ECB10-135A5M5M-I, where the core portion has the same meaning as ECK10-135A5M5M-I, with the ECB prefix identifying it as a single board computer rather than a core board. Industrial controllers (ECM series) add enclosure process and performance code fields that require separate interpretation.

Mastering EBYTE's industrial computing product numbering rules is like having a "quick-reference dictionary" for industrial core boards. It not only helps hardware engineers and project managers "know the configuration at a glance" but also significantly improves selection efficiency and team collaboration accuracy.

One-line Memory Rule: Remember the encoding logic of the six core fields — prefix, processor, package, memory, storage, temperature — and you'll be able to lock onto the right "industrial core" for your project in seconds, even from a vast product library.
