WM66xx serial Module includes WM6681 (WM6680), WM6690 (WM6691) and WM6615 three products.

WM66xx is a standard wireless module based on CDMA2000 1x technology. It provides a set of basic functions such as voice call, data service, LCD/Key pad connection and other flexible features for variety applications and customers. It can be used in wireless communications and many other value-added services.

WM6681 is designed to support 800MHz (cellular band) only. It¡¯s smaller, more stable, more functional, and easy to integrate. It can be widely used in CDMA 2000 1x net-works.

And WM6690/1 is designed to support 1900MHz (PCS Band) only, WM6615 is designed to support 450MHzBand (A, B, C, F Block).
