4.3.1 Antenna connector
An SMA female jack is available on the front side (see Figure 2) of the evaluation unit for connecting an active or
passive antenna. DC voltage at the RF input is 3.3 V. The internal short circuit protection limits the maximum
current to 60 mA. Please note that the 30 mA maximum supply current for active antenna stays the same. This
pin is also ESD protected.
To avoid the damage of RF input caused by ESD or Electrical Overstress, and to seek maximum consistency and
repeatability of performance independently of the RF component used, all EVK-7, EVK-8 and EVK-M8 have an
onboard LNA.
The connector is only to be used with a GNSS antenna or simulator. Do not connect this
equipment to cable distribution systems.
4.3.2 USB
A USB V2.0 compatible serial port is featured for data communication and power supply.
4.3.3 UART
The evaluation unit includes an RS232 port for serial communication that is compatible with PC serial ports.

per second during a GNSS fix. If there is no GNSS fix, the LED will only light, without flashing.
4.3.10 Backup Battery
There is a backup battery in the evaluation unit. This is necessary to store orbital information between operations
and to enable faster start-up. It is a RENATA 3.0 V Li / MnO² battery of the type CR2450. The battery has a rated
capacity of 540 mA. The battery operating temperature range is -40° C to +85° C.
In case the built-in backup battery runs low or empty after a long storage period, purchase the above described
battery for replacement (refer to the section 10 for battery replacement guidelines).
CAUTION! RISK OF EXPLOSION IF BATTERY IS REPLACED BY AN INCORRECT TYPE. DISPOSE OF
USED BATTERIES ACCORDING TO THE INSTRUCTIONS!
4.3.11 GNSS Configuration
The EVK-7 and EVK-8 supports GPS, QZSS and GLONASS. The EVK-M8N/C and EVK-M8MEVA/EVK-M8QEVA
supports GPS, Galileo, QZSS, GLONASS, and BeiDou.
The GNSS to be used can be configured on u-center (View Messages View then UBX-CFG-GNSS). For more
information, refer to the u-center User Guide [21], the u-blox 7 Receiver Description including Protocol
Specification [9] and u-blox 8 / u-blox M8 Receiver Description including Protocol Specification [20].
4.3.12 RTC Configuration (EVK-7EVA and EVK-M8MEVA)
The EVK-7EVA and EVK-M8MEVA include the EVA-7M or EVA-M8M GNSS receiver with an external RTC. By
default, the EVA-7M or EVA-M8M module is not running in single crystal mode. The EVK-7EVA and EVK-
M8MEVA evaluation kits can be set to single crystal mode by using the configuration string described in the
EVA-7M Hardware Integration Manual [8] and the EVA-8M / EVA-M8M Hardware Integration Manual [18].
Applying the configuration string results in a permanent change and cannot be reversed. The current
consumption is significantly higher in single crystal mode. For more information see the EVA-7M Data Sheet
[5], EVA-8M Data Sheet [25] and the EVA-M8M Data Sheet [13].

UBX-14002502 - R09 Early Production Information Testing Power Save Mode
Page 15 of 28
6Testing Power Save Mode
When testing Power Save Mode with EVK-7 / EVK-8 / EVK-M8, observe the following points:
When configuring Power Save Mode you must set up the parameters using the CFG-PM2 message first and
then enable Power Save Mode using CFG-RXM. The Configuration view or Messages view of the u-center
evaluation software can be used to do this. When enabling the mode using CFG-RXM, always save the
configuration by checking the “save configuration” box in u-center otherwise the configuration will be lost.
Communications to the evaluation kit must be via the UART, I2C or SPI (not USB).
The evaluation kit can be supplied via the USB connector or via V5_IN at the front panel connector. Do not
connect the USB cable to the PC! This can be done by either connecting a USB cable from the evaluation kit
to a USB hub, or by using a USB power connector.
When altering the Power Save Mode configuration, first disable the mode using CFG-RXM (remember to
enable “save configuration” again), before changing the CFG-PM2 parameters. Then re-enable Power Save
Mode.
EVK-7x supports GPS only in Power Save Mode.
