Beigaozhi 2.4G wireless two-way transparent data transmission module solution
chrispeng [ad_1]
Based on the Broadcom (BEKEN) BK2411 2.4G wireless transceiver chip, this solution is launched for industrial control, access control, attendance, monitoring, security and other industry application characteristics.
There are many solutions for 2.4G wireless modules on the market, and these solutions are basically the integration of typical application circuits of different RF chips. Although these schemes have brought convenience to users to a certain extent, they still need to do a lot of software design work in the specific application of customers, which delays the time to market for customers’ products.
This solution is specifically aimed at industrial applications such as wireless industrial control, monitoring, security, access control, and time attendance, and is a real solution integration. No need to do any extra work, only need to add power to realize its most basic functions, do not need customers to slowly study the register configuration of complex RF chip and read and write instruction data, completely achieve data Transparent transmission.
