REB-3310 Operational Manual RoyalTek GPS Module: REB-3310 Operational Manual Introduction RoyalTek REB-3310 low power and small form factor board is the newest generation of RoyalTek GPS Receiver. The GPS receiver is powered by SiRF Star III technology and RoyalTek proprietary navigation algorithm that providing you more stable navigation data. The smallest form factor and miniature design is the best choice to be embedded in a portable device like PDA, personal position and navigation like personal locator, speed camera detector and vehicle locator. The excellent sensitivity of REB-3310 gets the great performance when going though the urban canyon and foliage. Product Features 20 parallel channels Extreme fast TTFF at low signal level Operable from 3.3V/72mA continuous mode. SMT type with stamp holes Pin reserved for Backup battery and RF connector TCXO design 7 I/O lines(GPIO) available to connect 0.1 second reacquisition time Small form factor. NMEA-0183 compliant protocol/custom protocol. Enhanced algorithm for navigation stability Excellent sensitive for urban canyon and foliage environments. SBAS (WAAS, EGNOS and MSAS) support Auto recovery while RTC crashes Trickle power supported ARM 7 CPU core accessible. 4/8/16Mbits Flash Memory. Product applications Automotive navigation Personal positioning and navigation Marine navigation Timing application 3

REB-3310 Operational Manual Application Circuit (1) Ground Planes: REB-3310 GPS receiver needs two different ground planes. The GND_A pin(11B 12B13B14B15B16B18) shall be connect to analog ground. The GND pin(2B10B30) connect to digital ground. (2) Serial Interface: The Serial interface pin(RXABTX1BTXBBRXB) is recommended to pull up(10K[). It can increase the stability of serial data. (3) Backup Battery: It’s recommended to connect a backup battery to V_BAT. In order to enable the warm and hot start features of the GPS receiver. If you don’t intend to use a backup battery, connect this pin to GND or open. If you use backup battery, shall need to add a bypassing capacitor (10uF) at V_bat trace. It can reduce noise and increase the stability. (4) Antenna: Connecting to the antenna has to be routed on the PCB. The transmission line must to controlled impedance to connect RF_IN to the antenna or antenna connector of your choice. (5) Active antenna bias voltage: The Vcc_RF pin (pin 20) is providing voltage 3.0V. If you use active antenna, you can connect this pin to V_ANT_IN pin (pin 19) to provide bias voltage of active 8
