The **M2PHSW-A1-R** is a specific electronic component primarily identified as a **Micro-HDMI (Male) to HDMI (Female) Adapter**. These parts are commonly used in mobile devices, single-board computers (like Raspberry Pi 4), and cameras to interface with standard display cables. --- ### 1. Component Specifications The electronic architecture of this adapter is designed to maintain signal integrity while converting the physical form factor of the HDMI interface. | Feature | Specification | | :--- | :--- | | **Connector A** | Micro-HDMI (Type D) Male | | **Connector B** | Standard HDMI (Type A) Female | | **Interface Standard** | HDMI 1.4 / 2.0 Compatible | | **Maximum Resolution** | Up to 4K @ 60Hz (depending on cable length) | | **Plating** | Gold-plated connectors for corrosion resistance | | **Housing Material** | High-density PVC or ABS Plastic | --- ### 2. Internal Electronic Structure While it appears to be a simple mechanical bridge, the internal "parts" include: 1. **Passive PCB Bridge:** Inside the molding, there is a small, multi-layer Printed Circuit Board (PCB). This board maps the 19 pins of the Micro-HDMI connector to the 19 pins of the standard HDMI connector. 2. **Pin Mapping:** It ensures that the High-Speed Differential Pairs (TMDS) are shielded correctly to prevent Electromagnetic Interference (EMI). 3. **Shielding:** A metal internal shield (usually tin-plated steel or copper) surrounds the PCB to protect the digital signal from external noise. 4. **Strain Relief:** The "R" in the part number often refers to the RoHS compliance or a specific structural reinforcement (Revision) that prevents the internal solder joints from snapping under tension. --- ### 3. Pinout Configuration Since this is a passive adapter, the electronic logic follows the standard HDMI mapping: | Pin Group | Function | | :--- | :--- | | **TMDS Channels** | Carries the digital video and audio data. | | **DDC (Display Data Channel)** | Allows the source to read the monitor's EDID (resolution/timing info). | | **HEAC** | HDMI Ethernet and Audio Return Channel. | | **+5V Power** | Provides low current for the display's logic circuits. | --- ### 4. Common Use Cases * **Raspberry Pi 4 / 5:** Converting the Micro-HDMI output to a standard monitor cable. * **Action Cameras:** Connecting a GoPro or similar camera directly to a TV. * **Thin Laptops:** Connecting ultrabooks with limited port space to projectors.
