2. Setup and Installation

Proper installation is crucial for the optimal performance of your Wxt2Hm2001 Mt7921Asn module. Please follow these steps carefully:

1. Prepare the Host System: Ensure your host device (e.g., laptop, desktop, embedded system) has a compatible slot (e.g., M.2, PCIe, or appropriate soldering pads) for the module. Power off the host system and disconnect it from any power source before proceeding.
2. Handle with Care: Electronic modules are sensitive to electrostatic discharge (ESD). Use an anti-static wrist strap or take other ESD precautions when handling the module. Avoid touching the gold contacts or components directly.
3. Insert the Module: Carefully align the module with the designated slot on your host system. Gently push the module into the slot until it is fully seated. Secure the module with any retaining screws or clips provided by your host system manufacturer.
4. Connect Antennas: Attach the appropriate Wi-Fi and Bluetooth antennas to the connectors on the module. Refer to Figure 1 for the location of the antenna connectors (BTG, WFD, WFT, BTI). Ensure the antenna cables are securely connected.
5. Power On and Install Drivers: Once the module is physically installed, reassemble your host system and power it on. You will likely need to install specific drivers for the Mt7921Asn chipset to enable Wi-Fi and Bluetooth functionality. These drivers are typically provided by your host system manufacturer or can be found on the chipset manufacturer's website.
