Candidates
Garmin Geko 301
The Garmin Geko 301 is a candidate GPS for use with the Raspberry Pi on projects such as RaspberryTortoise. It is an obsolete hand held GPS system designed for Hiking and GPS games.
Advantages
- Small and low power for a hand held GPS.
- Differential GPS that gives added accuracy, this works in the UK using free european satellites designed to provide this additional differential GPS service.
- Electronic compass to provide orientation.
- Supports standard NMEA messages
- RS232 serial is simple to use
- Barometer for altitude. (For when RaspberryTortoise gets its rocket pack)
- Acts as a GPS data logger
- Has potential to contain preloaded tracks or waypoints for navigation.
- Will potentially calculate additional information such as speed or distance away from a route.
- Software available to manage data on GPS.
- Obsolete and can be found for sale second hand. (not colour or USB so considered outdated)
Disadvantages
- Bigger than a GPS module
- Requires two AAA batteries or a 3.0v supply. (3.3v is NOT close enough)
- Connector is not standard.
- RS232 level outputs require level shifter for Raspberry Pi input.
- Discontinued.
