VPN1513 GPS Receiver Module (#28506)
The VPN1513 GPS Receiver Module provides a fully open source and customizable GPS Receiver solution
for your microcontroller projects. The VPN1513 uses a SiRF Star III chipset capable of tracking up to 20
satellites. The module supports both “raw” output mode for raw NMEA 0183 strings and the default
“smart” mode for specific user-selected data through a serial interface.
The VPN1513 GPS Receiver Module also features a Propeller co-processor for easy interface with any
BASIC Stamp 2 module. The Propeller is also fully reprogrammable and includes access to all 32 IO pins,
allowing the GPS Receiver Module to be easily transformed into a standalone device.

the VPN1513 GPS Receiver Module product page. Go to www.parallax.com and search 28506.
Product Details
The VPN1513 GPS Receiver Module provides a powerful off-the-shelf GPS solution for microcontroller
projects. The onboard Propeller microcontroller co-processor allows for easy interface to all BASIC Stamp
modules and with access to all 32 (fully reprogrammable) Propeller IO pins, provides an easy port to a
standalone device.
Mode Selection
By default, users receive GPS data utilizing a serial interface through a Propeller co-processor (also
known as “Smart” mode). Users may also choose to receive raw NMEA0183 strings utilizing the /RAW
pin. Details on both modes are included in the table below.
Mode Details
SMART Selected by default. User retrieves GPS information by sending ASCII commands to the
module.
RAW Selected by pulling the /RAW pin LOW. When low, the module outputs raw NMEA0183
strings.
Indicator LED
Satellite acquisition with this module is fast: ~47 seconds for a cold start, ~38 seconds for a warm start,
and ~1 second for a hot start. The VPN1513 GPS Receiver Module has an onboard red indicator LED for
easy visual feedback of satellite acquisition.
Status Details
Blinking No satellites acquired, searching
Solid Satellite fix, transmitting data

Module product page.
Command Set
By default, the VPN1513 GPS Receiver Module runs in “Smart Mode,” where the user can send serial
messages to the GPS Module and have data returned to a microcontroller through the Propeller
microcontroller co-processor. (These values are identical to the #28146 Parallax GPS Receiver Module.)

BASIC Stamp®Example Code
The VPN1513 GPS Receiver Module is compatible with the GPSDemoV1.1.bs2 code written by Joe Grand
for the Parallax GPS Receiver Module (#28146), by changing the baud rate to 9600. This modified code
can be downloaded from the VPN1513 GPS Receiver Module’s product page, visit www.parallax.com and
search “28506”.
This program also uses the Debug Terminal, which is built into the BASIC Stamp Editor software. The
software is a free download from www.parallax.com/basicstampsoftware.
