SIM2000S Overview
SIM2000S is a single CDMA module, which works on frequency 450MHz (BC5).
With a tiny configuration of 24*24*3mm, SIM2000S can meet almost all the space requirements in user
applications, such as smart phone, PDA and other mobile devices.
SIM2000S has 68 SMT pads, and provides all hardware interfaces between the module and customers’ boards.
