• Go to file
• Retrieve
• Import file with GPS Babel
• Choose (at the end of the list) : universal csv with field structure in first line
• Add a map in layer
• Use Open Street Map (Mapnick) or Bing Aerial

Buzzer

The buzzer will tell you if there is any issues with the gps/ micro sdcard

• Heavy sound : Wiring issues or no microsd
• Soft repetitive sound : GPS is calibrating (can take up to 5 minutes)
• Melody : GPS is online
• Soft and short sound : GPS coordinates saved to sd

Batttery pack placement

As stated by bwh13 on instructables : You should avoid obstructing the antenna with the battery pack

Nice project.
Moving forward, consider placing your battery pack beneath your GPS module. The antenna works best with an unobstructed view of the sky

Tips Hendrik

Beim Flashen:

GND auf GND
VCC auf VCC
RX auf TX
TX auf RX
DTR auf DTR
CTS bleibt offen

mit geschickt hinlegen kann man ohne anzulöten flashen Prozessor auf ATMega328P (3,3V,8MHz) stellen und richtigen COMport wählen, dann kompilieren u hochladen
