The **N132-R** refers to a high-performance, compact **Single Board Computer (SBC)** or System-on-Module (SoM) typically based on the **Rockchip RK3328** or **RK3566** architectures (depending on the specific manufacturer variant, such as those from FriendlyElec or Firefly). It is widely used in networking, IoT gateways, and edge computing. Below is a breakdown of its primary electronic components and specifications: --- ### 1. Core Processing Unit The heart of the N132-R is its SoC (System on Chip), which integrates the CPU and GPU. | Component | Specification (Typical) | | :--- | :--- | | **CPU** | Quad-core ARM Cortex-A53 or A55 | | **GPU** | Mali-450 MP2 or Mali-G52 (supports 4K decoding) | | **Architecture** | 64-bit RISC | ### 2. Memory and Storage The board uses high-speed volatile memory and non-volatile flash storage. * **RAM (LPDDR3/LPDDR4):** Usually equipped with 1GB or 2GB of RAM. It handles active processes and multitasking. * **eMMC Flash:** On-board industrial-grade storage (ranging from 8GB to 32GB) for the operating system (Linux/Android). * **MicroSD Slot:** Used for external storage expansion or booting the system from an SD card. ### 3. Networking Interfaces The "N" in the series often highlights its networking capabilities. * **Ethernet Controller:** Typically features a **Gigabit Ethernet (10/100/1000Mbps)** port. * **Wi-Fi/Bluetooth:** Integrated module (often via RTL8821 or similar) supporting Dual-band 2.4GHz/5GHz and BT 4.2/5.0. * **Antenna Header:** IPX/U.FL connectors for external signal amplification. ### 4. Connectivity & I/O Pins To interact with other hardware, the N132-R includes several physical interfaces: | Interface Type | Description | | :--- | :--- | | **USB Ports** | 1x USB 3.0 (Host) and 1x USB 2.0 (OTG/Host). | | **GPIO Header** | 20-40 pin headers for I2C, UART, SPI, and PWM. | | **Video Output** | HDMI 2.0a supporting up to 4K @ 60Hz. | | **Debug Port** | Dedicated 3-pin UART header for serial console access. | ### 5. Power Management * **PMIC (Power Management IC):** A dedicated chip (like the RK805) regulates voltage levels for the CPU, DDR, and I/O to ensure stability and energy efficiency. * **Input Power:** Usually powered via USB Type-C or a DC Jack (5V/2A or 5V/3A). --- ### Hardware Block Diagram Concept ```mermaid graph TD SOC[Rockchip SoC] --> DDR[RAM LPDDR4] SOC --> EMMC[eMMC Storage] SOC --> ETH[Gigabit Ethernet] SOC --> USB[USB 3.0 / 2.0] SOC --> HDMI[HDMI Out] PMIC[Power Management IC] --> SOC ```
