Introduction
RoyalTek REB-3300 low power and small form factor board is the newest generation of
RoyalTek GPS Receiver. The GPS receiver is powered by SiRFStarIIe/LP technology with
XTrac 2.0 firmware 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-3300 gets the
great performance when going though the urban canyon and foliage.

(1) Ground Planes:
REB-3300 GPS receiver needs two different ground planes. The GND_A pin(11、
12、13、14、15、16、18) shall be connect to analog ground.
The GND pin(2、10、30) connect to digital ground.
(2) Serial Interface:
The Serial interface pin(RXA、TX1、TXB、RXB) is recommended to pull up(10KΩ).
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
