The **M2AS1-5111-R2/CE** is a high-performance, embedded computing module, typically identifying as a **COM Express (Computer-on-Module)** or a specific industrial motherboard variant often associated with manufacturers like *ADLINK* or *Aaeon*. Based on the model nomenclature, it generally belongs to the **COM Express Type 6** or **Type 10** family, designed for rugged industrial automation, medical imaging, and telecommunications. --- ### 1. Key Technical Specifications Below is a breakdown of the typical hardware architecture for this series of electronic parts: | Component | Specification Details | | :--- | :--- | | **Processor (CPU)** | Usually features Intel® Core™ i-Series (6th/7th Gen) or Xeon® processors. | | **Chipset** | Intel® PCH (Platform Controller Hub) integrated for high-speed I/O. | | **Memory** | Dual-channel DDR4 SO-DIMM slots (up to 32GB or 64GB). | | **Graphics** | Integrated Intel® HD Graphics with support for 4K resolution. | | **Form Factor** | COM Express Basic or Compact (95 x 95 mm or 125 x 95 mm). | | **Operating Temp** | Standard (0°C to 60°C) or Extreme (-40°C to +85°C). | --- ### 2. Major Electronic Subsystems The board is composed of several critical layers of electronic components: #### A. Power Management Integrated Circuits (PMICs) The board utilizes multi-phase Voltage Regulator Modules (VRMs) to step down input voltage (usually +12V) to the low voltages required by the CPU (Vcore), often involving high-frequency inductors and solid capacitors for stability. #### B. High-Speed Connectivity Interfaces * **PCI Express (PCIe):** Supports Gen3 lanes for external GPU or high-speed FPGA expansion. * **SATA III:** 6Gb/s ports for storage. * **Ethernet:** Integrated Intel® GbE controllers (e.g., i219 or i210). #### C. Signal Integrity Components Because this is a high-density PCB, it includes: * **Termination Resistors:** To prevent signal reflection on high-speed buses. * **Decoupling Capacitors:** Small ceramic capacitors (MLCCs) placed near the CPU to filter high-frequency noise. * **EMI Shielding:** Specialized layering in the PCB to prevent electromagnetic interference. --- ### 3. Pinout and Connector Interface The "R2" in the name often signifies a **Revision 2** hardware update, which usually improves power efficiency or adds support for newer BIOS/UEFI features. The module connects to a "Carrier Board" via high-density connectors: ```text [ COM Express Module ] <--- (Row A/B & C/D Connectors) ---> [ Carrier Board ] | | (CPU/RAM/PCH) (USB/LAN/VGA/Power) ``` --- ### 4. Typical Applications * **Medical:** Ultrasound and MRI processing units. * **Industrial:** High-end PLC (Programmable Logic Controllers). * **Military:** Ruggedized field computers.
