The **M2AVS-A1112-R2/N** refers to a high-performance, industrial-grade camera module, specifically part of the **Basler dart** series. This device is an area scan camera designed for embedded vision applications. Below is a breakdown of its electronic components and technical specifications. --- ### 1. Core Technical Specifications The electronics are built around a CMOS sensor and a high-speed data interface designed for lean integration. | Feature | Specification | | :--- | :--- | | **Sensor Type** | CMOS (Global Shutter) | | **Sensor Model** | Sony IMX273 | | **Resolution** | 1440 px x 1086 px (1.6 MP) | | **Frame Rate** | 165 fps | | **Interface** | USB 3.0 (Micro-B) | | **Pixel Size** | 3.45 µm x 3.45 µm | | **Video Output Format** | Mono 8, Mono 12, Mono 12p | --- ### 2. Electronic Sub-Systems #### A. Imaging Sensor (Sony IMX273) The heart of the module is the Sony Pregius IMX273 sensor. * **Global Shutter:** Unlike rolling shutters, this electronic component captures all pixels simultaneously, eliminating motion blur in high-speed applications. * **Quantum Efficiency:** Optimized for high sensitivity in both visible and near-infrared (NIR) spectrums. #### B. The Interface (USB 3.0) The "R2" designation often refers to specific revision or connector orientations. * **Power Delivery:** The camera is "bus-powered," meaning it draws its DC power directly from the USB 3.0 interface (typically 5V). * **Data Throughput:** Uses the USB3 Vision standard to ensure low-latency data transfer to the host processor. #### C. Internal Processing (FPGA/ASIC) Internal electronics include an integrated circuit (often an FPGA) that handles: * **Debayering:** (If color version) converting raw data to RGB. * **Image Pre-processing:** Auto-exposure, gain control, and white balance are calculated on-board to reduce the CPU load of the host device. * **Digital I/O:** The module includes a general-purpose I/O (GPIO) lines for triggering the camera or controlling an external strobe light. --- ### 3. Physical Form Factor The "M2" in the prefix usually denotes the **S-mount** (M12) lens adapter compatibility. * **Board Level:** This is a "bare board" camera, meaning the electronics are exposed (no housing). This is intended for integration into larger machines or medical devices. * **Dimensions:** Roughly 27 mm x 27 mm, making it ideal for space-constrained electronics assemblies. --- ### 4. Connectivity Pinout (Internal) While the primary data goes through USB, there is an internal 6-pin connector for electronic synchronization: ```json { "Pin 1": "VBUS (USB Power)", "Pin 2": "D- (USB Data)", "Pin 3": "D+ (USB Data)", "Pin 4": "GND", "Pin 5": "I/O 1 (Opto-Isolated Input)", "Pin 6": "I/O 2 (Open Collector Output)" } ```
