EVK-F10T - User guide Product description 1.1 Overview The u-blox EVK-F10T evaluation kits make evaluation of all features of the u-blox F10 GNSS timing simple. For an overview of u-blox NEO-F10T features, see the product page on the u-blox website: www.u-blox.com/en/product/neo-f10t-module.
62368-1:2018 [5] for more information on the PS1 class. In addition to a limited power source, only ES1 class circuits are to be connected to the EVK-F10T, including interfaces and antennas. See section 5.2.1.1 of IEC 62368-1:2018 [5] for more information on the ES1 class.
EVK-F10T - User guide Getting started 3.1 Installing u-center 2 software u-center 2, the u-blox interactive evaluation software tool is required for configuration, testing, visualization, and data analysis of u-blox GNSS receivers as well as EVKs. The EVK user guide together with the u-center 2 evaluation tool provide useful assistance during all phases of a system integration project.
EVK-F10T - User guide Device description EVK-F10T evaluation kit contains u-blox NEO-F10T GNSS receiver with RTC, SPI flash memory, TCXO and SAW filter. 4.1 Interface connection The EVK-F10T supports UART and USB (serial to USB communication) interfaces. To connect the EVK to a PC, use the included USB cable depending on the interface in use.
4.1.1 14-pin connector The EVK-F10T front side has a 14-pin connector that provides programmable input/output signals, communication interfaces and power supply options. All these pins are ESD protected. The 14-pin connector can be used for communicating with the receiver through the 3.3V UART interface. In addition, the 14-pin connector provides flexibility for evaluating other advanced scenarios.
To evaluate the GNSS reception, the GNSS signal must be supplied to the antenna input SMA connector of the evaluation kit. EVK-F10T evaluation kit includes ANN-MB1 multi-band (L1/L5) active GNSS antenna with a 3 m cable. It is possible to connect various active GNSS antennas with SMA connectors or provide a signal from a recorded or simulated GNSS RF source to the antenna input.

The time pulse signal is configurable. For details, see the Interface description [2]. 4.7 Flash memory EVK-F10T has an 8-Mbit SPI flash built-in in the NEO-F10T receiver. It can be used to store the current configuration permanently. 4.8 External interrupt On the EVK-F10T, the external interrupt (EXTINT) signal is available on the 14-pin connector.
On EVK-F10T, the main supply voltage for the u-blox NEO-F10T GNSS receiver is 3.3 V. To measure the total GNSS supply current with EVK-F10T, follow these steps: Before starting the test, make sure you have good signals and clear sky view to ensure that the receiver can acquire the satellite signals.
