7 Connecting using the UART or SPI
The GNSS board can be interfaced with either UART or SPI. Connect the bard to 5V and GND and then
either connect UART or SPI interface to it. Remember to enable GPS_EN by connecting it to a pull-up
voltage of 3.3V. The pins used are shown below.
Connect and Antenna suitable for GNSS receivers to the Antenna U.FL connector.
