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
