2.1.2 Design considerations
For a minimal design with a u-blox 6 GPS module the following functions and pins need to be considered:
• Connect the Power supply to VCC.
• VDDUSB: Connect the USB power supply to a LDO before feeding it to VDDUSB and VCC. Or connect to
GND if USB is not used.
• Assure a optimal ground connection to all ground pins of the module
• Connect the antenna to RF_IN over a matching 50 Ohm micro strip and define the antenna supply
(V_ANT)
6
• Choose the required serial communication interface (UART, USB or DDC) and connect the appropriate pins
to your application
for active antennas (internal or external power supply)
• If you need Hot- or Warmstart in your application, connect a backup battery to V_BCKP
• Decide whether TIMEPULSE or RESET_N
6
options are required in your application and connect the
appropriate pins on your module
