GPS Engine Board

MODEL: EB-12T

Overview

EB-12T is the newest generation of Sanav EB series GPS engine board. This low-powered, small form factor board is powered by SiRF Star III technology. The T-type design of EB-12T is the best choice for embedding in portable devices and receivers like PND, mobile phone, car holder, personal locator, digital camera, and vehicle locator. The high sensitivity of EB-12T provides great performance when going through the urban canyon and foliage.
