This solution adopts the BEKEN BK2411 2.4G wireless transceiver chip, and is launched for industrial application features such as industrial control, access control, attendance, monitoring, and security.
There are many solutions for 2.4G wireless modules on the market. These solutions are basically the integration of typical application circuits of different RF chips. Although these solutions have brought convenience to users to a certain extent, in the specific application of customers, a lot of software design work still needs to be done, which delays the time to market of customer products.
This solution is specifically aimed at wireless industrial control, monitoring, security, access control, time and attendance and other industry applications, and is a true solution integration. It does not need to do any extra work, only need to add power to achieve its most basic function, does not require customers to slowly study the complex RF chip register configuration and read and write command data, completely complete the data Transparent transmission.
