The **M2CEC-11501-R2** is a high-performance **Carrier Board** designed by AAEON, specifically tailored for the **NVIDIA® Jetson Orin™ Nano** and **Jetson Orin™ NX** System-on-Modules (SoM). It serves as the physical interface and power delivery system for these AI modules. --- ### 1. Key Technical Specifications The following table highlights the primary electronic components and connectivity options integrated into the R2 revision of this board: | Feature | Specification | | :--- | :--- | | **Module Support** | NVIDIA Jetson Orin™ Nano / NX (260-pin SO-DIMM) | | **Storage** | 1x M.2 2280 M-Key (NVMe PCIe x4) | | **Expansion** | 1x M.2 2230 E-Key (WiFi/BT), 1x M.2 3042/3052 B-Key (LTE/5G/SATA) | | **Ethernet** | 1x GbE RJ-45 (10/100/1000 Mbps) | | **USB Ports** | 2x USB 3.2 Gen 2 (Type-A), 1x Micro-USB (for Flash/Recovery) | | **Display** | 1x HDMI 2.0 (Supports up to 3840 x 2160) | | **Power Input** | 12V ~ 24V DC via 2-pin Terminal Block | --- ### 2. Functional Electronic Layout The board is engineered for industrial-grade Edge AI applications. Its electronic architecture is divided into three main sections: #### A. Power Management System * **Wide Voltage Input:** The board features a robust power circuit capable of handling **12V to 24V DC**. This makes it suitable for both stable laboratory environments and fluctuating industrial power grids. * **Protection Circuits:** Includes over-voltage and over-current protection to safeguard the expensive Jetson Orin module. #### B. High-Speed Signal Routing * **PCIe Lanes:** The PCB layout is optimized for high-speed differential signals. It routes the PCIe Gen 3/4 lanes from the Orin module to the M.2 slots to ensure maximum data throughput for NVMe SSDs and 5G modems. * **CSI Interfaces:** Typically supports MIPI CSI-2 camera interfaces via specialized connectors, allowing for low-latency image processing. #### C. Connectivity and I/O * **Serial Communication:** Includes headers for UART, RS-232/422/485, and I2C, enabling communication with sensors, PLCs, and microcontrollers. * **Digital I/O:** Provides a 4-bit or 8-bit DIO (Digital Input/Output) header for triggering external hardware events. --- ### 3. Usage Context Because of its small form factor and rugged power design, the M2CEC-11501-R2 is commonly found in: 1. **Autonomous Mobile Robots (AMR):** Using the M.2 slots for 5G connectivity and NVMe storage for map data. 2. **Smart City Infrastructure:** Connecting high-resolution cameras via HDMI and Ethernet for real-time traffic analytics. 3. **Industrial Inspection:** Utilizing the GPIOs to interface with conveyor belt sensors and actuators.
