EB-230 Data Sheet
3 User Interface
EB-230 provides 2- wire digital UART port for communication of GPS position data
using NMEA protocol or MTK extension protocol. UART port is capable of 4800 to
115200 baud rate. Additional 5-pin SPI port is provided for connection with external
sensors such as compass, gyro…etc. SPI port share same pin location with general
purpose input / output pins (pin #10 ~14).
3.1 Protocol
EB-230 is default to support standard NMEA-0183 protocol. In addition, a series of
MTK extensions (PMTK messages) have been developed that can be used to
provide extended capabilities common to many applications.
To achieve optimal compatibility it is intended to implement 100% compatible
operating modes to existing protocols since these protocols are largely symmetrical
and designed to provide a bi-directional exchange of data between GPS equipments.
3.1.1 NMEA Protocol
