SIM08 GPS Module

SIMCom presents a high performance host-based GPS module-SIM08, It cooperates with SIM900 which host the GPS
software inside for many wireless applications, such as automotive, tracking, etc.  With Embedded AT running inside
SIM900, it will eliminate the needs of external MCU to lower the total product cost and enables faster time-to-market.
