SIM908 Description 1.1 Summarize Designed for global market, SIM908 is integrated with a high performance GSM/GPRS engine and a GPS engine. The GSM/GPRS engine is a quad-band GSM/GPRS module that works on frequencies GSM 850MHz, EGSM 900MHz, DCS 1800MHz and PCS 1900MHz. SIM908 features GPRS multi-slot class 10/ class 8 (optional) and supports the GPRS coding schemes CS-1, CS-2, CS-3 and CS-4. The GPS solution offers best- in-class acquisition and tracing sensitivity, Time-To-First-Fix (TTFF) and accuracy. With a tiny configuration of 30*30*3.2mm, SIM908 can meet almost all the space requirements in user applications, such as M2M, smart phone, PDA, tracker and other mobile devices. SIM908 has 80 SMT pads, and provides all hardware interfaces between the module and customers’ boards. � Serial port and debug port can help user easily develop user’s applications. � GPS Serial port. � Two audio channels include two audio inputs and two audio outputs. These can be easily configured by AT command. � Charging interface. � Programmable general purpose input and output. � The keypad and SPI display interfaces will give users the flexibility to develop customized applications. � RF pad and connector interface. SIM908 is designed with power saving technique so that the current consumption is as low as 1.0mA in sleep
