The **M2AP-34-R2** is a high-performance, industrial-grade wireless Access Point (AP) module designed specifically for integration into embedded systems, IoT gateways, and industrial networking hardware. --- ## Technical Specifications The internal electronic components are built around the **IEEE 802.11ac (Wi-Fi 5)** standard, optimized for stability in harsh environments. | Component / Feature | Specification Details | | :--- | :--- | | **Form Factor** | M.2 Key A+E (2230) | | **Chipset Architecture** | Based on MediaTek or Qualcomm High-Performance SoCs | | **Wireless Protocol** | IEEE 802.11a/b/g/n/ac (Dual Band) | | **MIMO Support** | 2x2 MIMO (Multiple Input, Multiple Output) | | **Frequency Range** | 2.4 GHz and 5 GHz | | **Interface** | PCIe (Wi-Fi) and USB (Bluetooth/Auxiliary) | | **Max Throughput** | Up to 867 Mbps (5GHz) + 300 Mbps (2.4GHz) | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | --- ## Key Electronic Subsystems ### 1. The RF Front-End (RFE) The module features integrated **Power Amplifiers (PA)** and **Low Noise Amplifiers (LNA)**. These parts are critical for: * **PA:** Boosting the signal for long-range transmission. * **LNA:** Increasing sensitivity to pick up weak signals from distant clients. ### 2. M.2 Interface Connector Unlike standard USB dongles, the **M2AP-34-R2** utilizes the **M.2 (NGFF)** gold-finger interface. * **Power Rails:** Operates typically on a 3.3V DC input. * **Data Lines:** Uses high-speed differential pairs for PCIe signaling to ensure low latency. ### 3. Antenna Connectors The board usually features two **I-PEX MHF4** micro-connectors. These are significantly smaller than the older U.FL connectors and are used to connect external antennas via pigtail cables. ### 4. Thermal Management The "R2" revision often includes improved thermal pads or a dedicated heat spreader. Because high-speed Wi-Fi 5 processing generates significant heat, the electronic layout is designed to dissipate energy through the M.2 ground plane. --- ## Connectivity Pinout (Typical M.2 A+E) ```text Pin Range | Function | Description ----------|----------------|-------------------------- 1-75 | PCIe / USB | Data transfer to Host CPU Power | 3.3V / GND | Main Voltage Supply Control | W_DISABLE# | Hardware Radio Kill Switch Status | LED_WWAN# | Visual activity indicator ``` ---
