GPS Module (SBS-2530)
The SBS-2530 is the newest generation of KNCTEK GPS Smart Antenna Receiver which was integrated with GPS function and Patch antenna into one module. The GPS Smart Antenna receiver is powered by SkyTraq technology and KNCTEK proprietary navigation algorithm that providing you more stable navigation data. The miniature design is the best choice to be embedded in a portable device like PND, PDA, Telematics and vehicle locator. The excellent sensitivity of SBS-2530 gets the great performance when going though the urban canyon and foliage environmental condition.

VCC DC Power Input
This is the main power supply for the Engine board. The power range is DC +5V ±10% ( 3.3V to 5.5V Acceptable ). Suitable decoupling must be provided by external decoupling circuitry.
GND
GND provides the ground for the Engine board. Connect all grounds.
TXD
NMEA_TX, UART output, 3.3V LVTTL logic level. This is the main transmit channel and is used to output navigation and measurement data to user written software. The default setup is NMEA
Output, 9600bps, 8 data bits, no parity, 1 stop bit. The default sentences are GPGGA, GPGSA, GPRMC,GPGSV once per second.
RXD
NMEA_RX, UART input,3.3V LVTTL logic level. This is the main receiving channel and is used to receive software commands to the Engine board from user written software.
