There are many types of Wi-Fi modules, and the selection of Wi-Fi modules mainly considers the following aspects:
- l. Application scenarios of the product and the functions to be implemented;
- 2. Understand the interfaces (master slave devices,functions, and special interfaces) that can be provided to implement the required functions in the Wi-Fi solution design;
- 3. Consider the power supply, size, power consumption,communication frequency band,transmission rate, transmission distance, etc of the Wi-Fi module;
- 4. Cost performance and its specificity.The Wi-Fi module belongs to the transport layer of the Internet of Things.
The Wi-Fi module is based on an embedded module that meets the Wi-Fi wireless network standards, with built-in wireless network protocols such as the IEEE 802.11 protocol stack and the TCP/IP protocol stack. Due to its fast transmission rate, which is sufficient to meet the rate requirements of most 1peripherals,it is widely used in wireless connection related fields.
The FEASYCOM FSC-BW110 module is based on the Ruiyu chip RTL8723DS. t provides an SDIO interface for Wi-Fi to connect to the host processor, and provides a 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/n MIMO technology..Wi-Fi throughput can reach 150Mbps, and Blue tooth supports BT2.1+EDR/BT3.0 and BT4.2.
The FSC-BW110 module uses a highly integrated Wi-Fi/BT chip with advanced COMS technology. TheRTL8723DS integrates the entire Wi-Fi/BT function block into a single chip, such as SDIO/UART, MAC, BB, AFE, RFE,PA，EEPROM，and LDO/SWR. However, fewer passive components are retained on PCB. This compact module is the overall solution for the combination of Wi-Fi+BT technology, and is specifically developed for tablets,smart business display POS machines, and portable devices.
