1 Introduction  
RoyalTek RSA-1500L low power and small form factor board is the newest generation  
of RoyalTek smart antenna GPS module. The smart antenna GPS module is powered  
by SiRF Star III technology and RoyalTek proprietary navigation algorithm that  
providing you more stable navigation data. Parallel design is the major new feature of  
RSA-1500L.  
The smallest form factor and parallel design is the best choice to be embedded in a  
portable device and receiver like PND, mobile phone, car holder, personal locator,  
digital camera and vehicle locator. The excellent sensitivity of RSA-1500L gets the  
great performance when going though the urban canyon and foliage

1.5 Application Circuit  
Figure 1-4 Application Circuit Reference  
Note:  
(1) Ground Planes:  
This pin2 should be connect to ground.  
(2) Serial Interface:  
() The TXA pin is recommended to connect to serial resistance(220Ω)  
and pull up (10KΩ). It can increase the stability of serial data. (Default  
NMEA)  
() The RXA pin is recommended to connect to serial resistance(220Ω)  
and pull up (10KΩ). It can increase the stability of serial data. (Default  
NMEA)  
(3) Backup Battery:  
When module is working, must to supply VCC pin(Pin1) and VBATT  
pin(Pin6) power at the same time.  
It’s recommended to connect a backup battery to VBATT pin.  
In order to enable the warm start and hot start features of the GPS receiver.  
If you use backup battery, should be add a bypassing capacitor (10uF) at  
VBATT pin. It can reduce noise and increase the stability.

RSA-1500L User Manual  
(4) Power:  
Connect VCC pin to DC 3.3V. The power supply must add bypass  
capacitor(10uF and 1uF).It can reduce the Noise from power supply and  
increase power stability.  
(5) GPIO:  
The GPIOs function are for customer used.  
If no use GPIO function, it don’t connect anything.

Definition of Pin assignment  
VCC(+3.3V DC power Input)  
This is the DC power supply input pin for GPS system. It provides voltage to  
module.  
GND  
GND provides the reference ground.  
TXA  
This is the main transmitting channel and is used to output navigation and  
measurement data to SiRFdemo or user written software  
RXA  
This is the main receiver channel and is used to receive software commands to  
the board from SIRFdemo software or from user written software.  
VBATT (Backup battery )  
When module is working, must to supply VCC pin(Pin1) and VBATT pin(Pin6)  
power at the same time.  
This is the battery backup input that powers the SRAM and RTC when main  
power is removed. Typical current draw is 10uA.  
The supply voltage should be between 2.5V and 3.6V.  
GPIO Functions  
Several I/Os are connected to the digital interface connector for custom  
applications.
