Foxtrotgps display
Note that the display of a live map, as shown, requires the pres-
ence of a working Internet connection and clear exposure to blue sky
for GPS signals. If you wish to see a real-time map while you are driv-
ing in a vehicle with this setup, you will need to use your smartphone
as a hot-spot and have the ODROID communicate with it via WiFi.
myAHRS+ board
If you are looking for an Attitude Heading Reference System
(AHRS), less inuenced by acceleration and magnetic disturbances,
the low cost USB2-based myAHRS+ board offered by Hardkernel is a
great choice. It also offers an I2C interface, which is useful in an em-
bedded application like Arduino-based projects.
It includes three sensors:
• triple axis 16-bit gyroscope : ± 2000 dps
• triple axis 16-bit accelerometer : ± 16 g
• triple axis 13-bit magnetometer : ± 1200 µT
