GPS Engine Board

MODEL: EB-12A

Overview

EB-12A 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. It’s a special design for the embedded applications such as portable devices and receivers like PND, mobile phone, car holder, personal locator, digital camera, and vehicle locator. The high sensitivity of EB-12A provides great performance when going through the urban canyon and foliage. Also, the EB-12A is ideal for variety of requirements that request the dimension of GPS module.

Features

- 20 parallel channels
- Excellent sensitivity for urban canyon and foliage environments
- Operable from 3.3V/ 48mA continuous mode
- TCXO design
- NMEA-0183 compliant protocol/custom protocol
- SBAS (WAAS, EGNOS and MSAS) support
- 4M bits Flash Memory
- Enhanced algorithm for the navigation stability
- Lead-free
- 0.1s reacquisition time

Applications

- Personal Navigation Device including GPS PDA and GPS Handheld
- Mobile phone and smart phone
- GPS receiver and GPS mouse
- Personal positioning and navigation
- Automotive/Marine navigation
- Timing application
