Figure 2: EVK-M8U evaluation unit –front and rear panels
3.3.1 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. The EVK provides a DC supply at the RF input of 3.3 V for active antennas. The maximum
supported antenna current is 30mA; internal protection limits the maximum short circuit current to 60 mA.
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, the EVK-M8U has 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.

3.3.8 LED
On the front panel of the unit, a single blue LED may be configured to follow the receiver time pulse signal using
message UBX-CFG-TP5. The time-pulse may be configured so that the LED starts flashing at one pulse per
second during a valid GNSS fix. If there is no GNSS fix, the LED will only light, without flashing. The time pulse is
enabled by default in EVK-M8U.
3.3.9 Backup battery
There is a backup battery in the unit. This is necessary to store calibration, dead-reckoning and orbital
information between operations to enable immediate start-up in DR mode and fast acquisition of GNSS signals.
It is a RENATA 3.0 V Li / MnO2battery of the type CR2450. The battery has a rated capacity of 540 mAh. The
battery operating temperature range is -40° C to +85° C.

3.3.10 GNSS configuration
The EVK-M8U 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 [4], and the u-blox 8 / M8 Receiver Description including Protocol
Specification [3].
4Setting up
4.1 EVK-M8U installation
The EVK-M8U ships with an active GPS / GLONASS / BeiDou magnetic mount antenna with 3 m cable.
The following sections describe the steps required to complete the EVK-M8U hardware installation.
4.1.1 Mounting the GNSS antenna
Attach the antenna to the car; for best performance attach it on the roof as shown in Figure 33. Bring the
antenna cable in through the window or door. Be careful not to damage the antenna cable.
4.1.2 Mounting the EVK-M8U
The EVK-M8U should be firmly attached to the car body so as to avoid any movement or vibration with respect
to the car body. The EVK should not be attached to any ‘live’ (unsprung) part of the vehicle’s suspension. Often
it is enough to use strong double sided tape or Velcro tape glued to the bottom of the EVK-M8U casing. If
necessary, mounting brackets may be attached using the end-plate retaining bolts (M3). The EVK must be
secured against any change in position and particularly orientation with respect to the vehicle frame.
The EVK case-work, antenna and USB connectors are linked internally to the common
supply/interface ground (pin 13).
Dead-reckoning performance will be seriously impaired by errors or changes in the orientation of the EVK.

Page 12 of 26
4.1.3 Connecting the cables
Unless using USB alone, we recommend using the ACE-AM-0 mating connector (available from the u-blox
webshop) because it locks securely to the front test connector. You will need to solder the necessary I/O cables
to signal sources and outputs as specified in Table 5.
1. Connect the finalized cable to the front connector of EVK-M8U.
2. Connect the unit to a PC running Microsoft Windows by
a. USB: Connect via USB port or
b. UART: Connect via RS232. Set slide switch to I2C or
c. SPI / I2C compliant DDC: Connect corresponding pins (see Table 4 for pin description). Set slide
switch accordingly to SPI or I2C.
3. Press the RST button after changing the SPI/ I2C switch.
4. The device may be powered either via USB or from a 5 V supply via the V5_IN input on the front.
5. Connect the RF cable of the GNSS antenna to the RF_IN connector.
6. Start the u-center GNSS Evaluation Software and select corresponding COM port and baud rate.
7. Refer to the u-center User Guide [4] for more information.
4.2 Recommended configuration
For an optimum navigation performance, the recommended configuration is as follows:
Navigation Rate: The default DR/GNSS-fused navigation solution update rate of 1 Hz is recommended.
You can set the navigation update rate with the message UBX-CFG-RATE. (In this mode navigation rates
up to 20Hz are also available from the UBX-HNR-PVT message.)

4.2.2 UDR receiver operation
By default, EVK-M8U is ready to operate in UDR navigation mode.
The statuses of different modes of UDR receiver are output in the UBX-ESF-STATUS message.
4.2.2.1 Initialization mode
The purpose of Initialization phase is to estimate all unknown parameters which are required for achieving
fusion. In this case the required sensor calibration status shows NOT CALIBRATED (see Figure 4). Note that
initialization phase requires good GNSS signals conditions as well as periods during which vehicle is stationary
and moving (including turns). Once all required initialization steps are achieved fusion mode is triggered and
calibration phase begins.

Page 13 of 26
Figure 4: Screenshot of u-center showing the INITIALIZING mode in UBX-ESF-STATUS message
4.2.2.2 Fusion mode
Once initialization phase is achieved, the receiver enters navigation mode and starts to compute combined
GNSS/Dead-reckoning fixes and to calibrate the sensor required for computing the fused navigation solution.
The sensor calibration status outputs CALIBRATING (see Figure 5).
Figure 5: Screenshot of u-center showing the FUSION mode in UBX-ESF-STATUS message
As soon as the calibration reached a status where optimal fusion performance can be expected, the sensor
calibration status are flagged as CALIBRATED (see Figure 6)

EVK-M8U User Guide
UBX-15023994 - R01 Advance Information Setting up
Page 14 of 26
Figure 6: Screenshot of u-center showing the sensor calibration as CALIBRATED
4.3 Accelerated initialization and calibration procedure
This section describes how to perform fast initialization and calibration of the UDR receiver for the purpose of
evaluation.
The duration of the initialization phase mostly depends on the quality of the GNSS signals and the dynamics
encountered by the vehicle. An open and flat area, such as an empty open-sky parking area, provides good
conditions. The initialization and calibration drive should contain phases where the car is stopped during a few
minutes (with engine turned-on), phases where the car is doing normal left and right turns, and phases where
speed is above 30 km/h under good GNSS reception conditions.
Note that the calibration status of some used sensors might fall back to CALIBRATING if the receiver is
operated in challenging conditions. In such a case, fused navigation solution uncertainty increases until
optimal conditions are observed again for re-calibrating the sensors.
For more information, see u-blox 8 / M8 Receiver Description including Protocol Specification [3].

Page 16 of 26
6Measuring tracking current
To measure the NEO-M8U module tracking current with EVK-M8U, follow these steps:
1. Connect a mean-reading voltmeter across P1A (VCC) and P1B of the front connector. (see Figure 91)
2. Wait 12 minutes to download all GNSS orbital data, or download all the Aiding Data via the AssistNow
Online service
3. Read the voltage (and average if necessary) on the voltmeter and convert to current (1 mV equals 1 mA)
4. Perform the test with good signals and clear sky view to ensure that the receiver can acquire the satellite
signals.
The NEO-M8U module current measurement includes its internal SQI flash, inertial sensor, and any current
delivered to SPI or I2C interface loads.
For more details see the circuit in Figure 12.
