WiFi module SKW103 low-power LAN interface

2024-05-09/ By Admin

The WiFi module SKW103 can effectively assist devices in completing information collection and data uploading, meeting the low-power, low-cost automation and sensor solution WiFi module requirements of the Internet of Things.

The data collected by the module is directly transmitted to the terminal through the serial port, or uploaded directly to the cloud. Users can access the system platform to retrieve data information, identify and verify the data, and correspond all data to device names one-to-one, reducing the probability of errors caused by manual on-site information collection.

WiFi module SKW103 product introduction

SKW103 is a WiFi module developed based on Qualcomm's QCA9531 solution, which has the following characteristics:

Working principle of WiFi module

The working principle of the WiFi module mainly includes the following steps:

1. Signal reception: The module receives RF signals sent by wireless network devices (such as wireless routers).

2. Demodulation: Demodulate radio frequency signals into digital signals.

3. Processing: Decoding and processing digital signals to extract useful information, such as data packets.

4. Transmission: The processed information is transmitted to the connected devices through the internal circuits of the module.

5. Feedback: The device encodes and modulates the data that needs to be sent through a WiFi module, converts it into an RF signal, and sends it out.
