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.
The author has designed a circuit controlled by a microcontroller, and can easily create an automatic hand dryer with a commonly used hair dryer. In addition to the above functions, it also has flashing lights and crisp audio prompts.
The LPCXpresso family provides a powerful and flexible development system for NXP Cortex-M microcontrollers. The LPCXpresso43S67 board was developed by NXP to enable evaluation and prototyping of the LPC4300 series MCUs, featuring the LPC43S67 in a 100-pin BGA package. LPCXpresso™ is a low-cost development platform provided by NXP that supports NXP's Arm-based microcontrollers. The platform includes a simplified Eclipse-based IDE and low-cost target boards with a JTAG debugger. LPCXpresso is an end-to-end solution that supports embedded engineers developing applications from initial evaluation to final production.
30 W, 155 - 165 MHz Evaluation Board based on PD55015-E
WT12 is a Bluetooth V2.1+EDR Class2 module from Bluegiga that fully integrates antenna, Bluetooth wireless reception and on-chip iWRAP Bluetooth protocol stack. For those customers who want to quickly integrate Bluetooth wireless reception technology into their designs and get the Bluetooth radio and protocol stack in time, Bluegiga's WT12 module will be a good solution. It integrates Bluegiga's iWRAP Bluetooth protocol stack: a Bluetooth protocol stack that embeds 13 different Bluetooth configurations and Apple iAP connectivity. With the iWRAP Bluetooth protocol stack and Bluegiga's excellent technical support, users of the WT12 module can not only shorten the time to market, but also reduce development risks and costs.
