As a wireless module R&D manufacturer for many years, Trolink has successively launched a variety of single-band and dual-band WiFi modules for video transmission applications in the security market. The following is an introduction for the convenience of security Manufacturer's WiFi module selection.

The WiFi module selection reference plan

1. The application scenarios of the product and the functions that need to be implemented;

2. Understand the calling interfaces (master-slave devices, functions, special interfaces) that can be provided to realize the required functions in the WiFi solution design;

3. Consider WiFi module power supply, size, power consumption, communication frequency band, transmission rate, transmission distance, etc.;

4. Cost performance and its particularity.

The WiFi module belongs to the transmission layer of the Internet of Things. The WiFi module is an embedded module based on the WiFi wireless network standard. It has a built-in wireless network protocol IEEE802.11 protocol stack and TCP/IP protocol stack . Because its transmission rate is fast enough to meet the rate requirements of most peripherals, it is widely used in wireless connection related fields.

This TL8723DSA WiFi module of Chuangling is based on Realtek chip RTL8723DS, which provides SDIO interface for WiFi to connect to the host processor, and high-speed UART interface for BT. It also has a PCM interface for audio data transmission and is directly connected to an external audio codec through a BT controller. Using 1x1 802.11nb/g/nmimo technology, WiFi throughput can reach 150Mbps, and Bluetooth supports BT2.1+EDR/BT3.0 and BT4.2.

This WiFi module uses a highly integrated WiFi/BT single-chip microcomputer with advanced COMS technology. TL8723DSA integrates the entire WiFi/BT functional block into one chip, such as SDIO/UART, MAC, BB, AFE, RFE, PA, EEPROM and LDO/SWR, but there are fewer passive components remaining on the PCB. This compact module is the overall solution of Wi-Fi+BT technology combination, this module is specially developed for smart phones and portable devices.
