The WF111 is a fully integrated single 2.4 GHz band 802.11 b/g/n module designed for portable and battery-powered applications requiring Wi-Fi connectivity. The WF111 integrates an IEEE 802.11 b/g/n radio, antenna or U.FL antenna connector, and SDIO host interface. It provides a low-cost and simple Wi-Fi solution for devices running an operating system and an onboard TCP/IP stack, but still offers the advantages of modules - small size, certification and ease of integration. Silicon Labs also provides WF111 drivers for Linux and Android operating systems. WF111 has hardware support for Wi-Fi encryption protocols.
BT121 is a Bluetooth dual-mode module suitable for applications requiring Bluetooth LE and BR/EDR connections. It can connect to older devices that only support Bluetooth SPP or Apple® iAP2 profiles as well as devices that support Bluetooth LE. The BT121 integrates a high-performance Bluetooth radio, a low-power ARM Cortex microcontroller and Bluegiga Bluetooth dual-mode stack software, requiring no RF or Bluetooth software development, making it very easy to use. The BT121 can be used as a modem with a separate host MCU, but applications can also be embedded into the built-in ARM® Cortex® MCU with the Bluegiga BGScriptTM scripting language.
In recent years, the development of wireless technology has gradually matured into an indispensable trend in daily life, such as WIFI, Bluetooth and 2.4GRF transmission, etc., which have brought many conveniences in life, and wireless speakers are one of them. In addition, the increasing development of wireless transmission technology has also led to the wirelessization of music peripheral products. This is a technological breakthrough, which also allows this type of product to have more imagination in the design, and also makes the fun of enjoying music more seamless. burden.
A microphone is a transducer that converts sound into electronic signals. It can transmit human speech to electronic devices to distant places or amplify the sound signal through speakers. In recent years, the development of wireless technology has gradually matured and become an indispensable trend in daily life, such as WIFI, Bluetooth and 2.4GRF transmission, etc., which have brought many conveniences in life, and wireless microphones are also one of them, allowing microphone users such as teachers to attend class. It is more convenient to go out with a tour guide to introduce attractions, speakers and karaoke singing.
In recent years, with the rapid development of wireless network technology and the improvement of bandwidth, wireless network audio and video streaming application products have become more and more popular, such as wireless network cameras, wireless baby monitors, Internet radios, and wireless speakers.
The smart phone dock speaker system can be connected to commonly used smart phones on the market such as Apple Iphone or Android phone, and can play audio and video files through docking connection. It is widely used in personal entertainment or home audio and video playback. The smart phone base speaker system must include a high-performance microcontroller to control USB signal conversion and transmission, LCD display transmission, power management, mobile phone charging, wireless remote control device reception, sound quality optimization chip control, etc. Since the working requirements of smart phone base speaker systems require high-performance microcontrollers with USB interfaces, Nuvoton's NUC123 series is very suitable for this application.
Commercial two-way wireless improves productivity—providing effective communications for mobile workforces such as restaurants, retail/departmental stores, warehouses, firefighters, hospitals, and more.
Today's smartphones/mobile tablets/tablet computers are all designed to play music and audio with high quality and low power consumption.
Today's smartphone/phablet/tablet designs require high-quality music and audio playback with low power consumption.
Telephone types can be divided into digital telephones and traditional telephones. The difference between the two lies in whether the signals transmitted are analog signals or digital signals. Digital telephones are different from traditional telephones in that they are less susceptible to interference and eavesdropping during calls, and they have the advantages of simple expandability and cord saving. Since digital phones require high-speed A/D conversion functions and high-speed data processing, including mathematical operations on digital signals, NuMicro M051 is extremely suitable for use in digital phone products.
Most smart controls combine RF functionality with smartphone control capabilities in affordable packages. These smart controls are unique universal remote systems capable of controlling multiple devices. The ISD9160 remote reference design is extremely thin and light, and operates via RF rather than infrared, so you don't need to point a straight line at your component. The ISD9160 smart control reference design combines RF functionality and smartphone control in an affordable, universal remote kit. The reference design also supports Skype/Voice calling, with the remote becoming a headset with volume control and microphone support. The remote control can also be used as an air mouse that supports ITG-3050 Gyro (3-axis) and MMA-8451 (3-axis) G sensor modules.
Laptops and desktop computers have become indispensable devices for businesses, families, and personal daily work lives. These devices have changed and improved human life in various aspects. Today, they have also evolved into tablet computers, Internet devices, smart phones and all-in-one computers, and continue to influence our lifestyles.
Using a 2.5V~5.5V wide voltage microcontroller, multiple control modules can be directly connected or the microcontroller itself can be used to realize seat warming functions, toilet seat temperature adjustment, flushing water temperature adjustment, flushing water flow intensity adjustment, automatic nozzle cleaning, etc. Function.
This solution has built-in various font font libraries, and various font font libraries can also be loaded through the NTD font conversion tool. It is equipped with a 2-inch OLED display customized graphics interface, and has high-speed GIF dynamic bitmap decoding (LZW), which can Play GIF animations smoothly.
The PM2.5 infrared module uses infrared turbidity detection method to detect fine dust with particles > 1 μm. The PM2.5 laser module uses a stable airflow system such as a fan or blower, and uses an optical sensor to identify dust particles > 0.3 μm.
