Datongda Holdings, a leading semiconductor component distributor dedicated to the Asia-Pacific market, announced that its subsidiary has launched the WLT2564S, a smart in-vehicle dual-mode Bluetooth solution based on STMicroelectronics (ST) STM32F103 and Texas Instruments (CC) CC2564. The car dual-mode Bluetooth solution can serve the inverter with 12v to 220v 1500w power converter. The user can connect to the mobile phone or tablet computer through Bluetooth wirelessly, and can monitor the various conditions of the intelligent power converter when working through the APP, such as Overload protection, short circuit protection, overvoltage protection, undervoltage protection, undervoltage alarm, overtemperature protection, battery power usage to converter alarm prompts, etc. related safety control and prompting functions.
With the increasing popularity of in-vehicle power inverters, people are more and more accustomed to using inverters to connect batteries to drive electrical appliances and various tools. When connecting household appliances to the output of power converters, people can Use a variety of electrical appliances inside the car. Mobile phones, laptops, digital video cameras, cameras, lights, electric razors, game consoles, laptops, power tools, car refrigerators, and various travel, camping, medical emergency appliances, etc. can be connected and charged using a car inverter. use.
The smart car dual-mode Bluetooth solution WLT2564S, which is launched by Dalian Dayou, can help users further realize the need to monitor and observe important information of power converters via mobile devices or to receive important alarm prompts in real time. The solution uses TI CC2564 Supports Bluetooth 4.0 and Dual-Mode (BR/EDR/LE) Controller, WLT2564S dual-mode Bluetooth transparent transmission module, and integrates STM32F103 series MCU, Flash (128KB-1M), RAM (20KB-96KB). The onboard adopts high-performance ceramic 2.4GHz antenna, which can be externally connected; the size is 19*30mm, which is the stamp hole pin; the system supports UART/SPI, the UART interface can reach up to 4Mbps; supports I2C interface, can be used for external encryption, support PCM interface, support I2S interface; support transparent protocol data transmission mode, can provide AT+ instruction set configuration; support Bluetooth SPP/SPPLE/HFP/MAP/PXP/A2DP/AVRCP/ANP/HID.
Dalian Dayou also provides a software platform for the smart car dual-mode Bluetooth solution. The platform can flexibly help engineers complete solution development and provide customized services.
