Page 9: Device Description
Figure 4.1 Interface connection The EVK-F101 supports UART, I2C and SPI communication interfaces . To connect the EVK to a PC, use a standard SUBD-9 cable or the included USB cable depending on the interface in use. The EVK includes an on-board USB-to-Serial converter for USB-to-UART communication with the receiver. -

RS-232 – back side or the 3.3 V level TXD/SDO, RXD/SDI pins at the front side). 4.1.2 14-pin connector The EVK-F101 front side has a 14-pin connector that provides programmable input/output signals, communication interfaces and supply options. All these pins are ESD protected. The 14-pin connector can be used for communicating with the receiver through the UART, SPI and I2C interfaces. -
Page 11: Usb
The USB connector in the evaluation kit can be used for both power supply and communication. The easiest way to evaluate the EVK-F101 operation is to connect the EVK to a PC with the USB cable and use the u-center 2 tool to configure and monitor the GNSS functions. The USB connector is internally connected to a USB-to-serial converter that connects to the UART interface of the u-blox F10 receiver in the EVK. -

Page 29: Troubleshooting
FTDI drivers are not automatically mapped in Linux environment EVK-F101 does not officially support Linux. The following example shows how to map the available FTDI drivers to the connected EVK. - Page 30 EVK-F101 does not work properly when connected to a GNSS simulator When using EVK-F101 together with a GNSS simulator, pay attention to proper handling of the EVK. A GNSS receiver is designed for real-life use (i.e. time is always moving forward). When using a GNSS simulator scenario, the scenario time can be in the past causing the receiver to jump backwards in time.
