1. Download and install the EVK-M8 software (and
documentation) from
www.u-blox.com/evaluation-kits.
See the installation notes on the back of this card.
2. Connect the unit to a PC. Options:
USB: Connect via USB port (G). (The USB driver
installs automatically when the device is connected
to a PC; internet connection required).
UART: Connect via RS232 (F). Set switch (B) to I2C.
SPI / I2C compliant DDC: Connect the pins (C).
Set switch (B) to either SPI or I2C.
NOTE: Press RST (E) after setting switch (B).
3. Provide power to the device at all times, either via
USB on the back (G) or the V5 IN pin (D) on the
front.
4. Connect the GNSS antenna to the evaluation unit
(A) and place the antenna in a location with an
unobstructed view of the sky. For best performance,
use an active antenna or external LNA (when con-
necting to a GNSS simulator).
5. Start the u-center GNSS Evaluation Software and
select the corresponding COM port and baud rate.
