1 Product description 1.1 Overview EVK-M8T evaluation kit makes evaluating the high performance u-blox M8T positioning products simple. The built-in USB interface provides both power supply and high-speed data transfer, and eliminates the need for an external power supply. The u-blox evaluation kits are compact, and their user friendly interface and power supply make them ideally suited for use in laboratories, vehicles and outdoor locations.
105 x 64 x 26 mm Power Supply 5V via USB or external powered via extra power supply pin 14 (V5_IN) 13 (GND) Normal Operating temperature -40°C to +65°C Table 2: EVK-M8T specifications UBX-14041540 - R04 Early Production Information Specifications Page 7 of 24...
3 Getting Started 3.1 Software installation Installation of the EVK-M8T software and documentation requires Internet access. Choose Software only or Software and documentation installation package from u-blox website. Once the zip file is downloaded and unzipped, unzip the file in Tools folder and double-click the extracted exe file.
GNSS antennas with SMA connectors to the evaluation unit. The recommended maximum antenna supply current for active antennas is 30 mA. 4.3 Evaluation unit Figure 2 shows the front and the rear panel of the EVK-M8T evaluation unit. Front panel Rear panel Figure 2: EVK-M8T evaluation unit –...
60 mA. Please note that the 30 mA maximum supply current for active antenna stays the same. This pin is also ESD protected. The u-blox NEO-M8T module used in the EVK-M8T incorporates an additional, off-chip LNA. The connector is only to be used with a GNSS antenna or simulator. Do not connect this equipment to cable distribution systems.

USED BATTERIES ACCORDING TO THE INSTRUCTIONS! 4.3.10 GNSS Configuration The EVK-M8T supports GPS, QZSS, Galileo, 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 [5], the u-blox 8 / u-blox M8 Receiver Description including Protocol Specification [4].
EVK-7 / EVK-M8 User Guide 5 Measuring tracking current To measure the tracking current with EVK-M8T, follow these steps: 1. Connect a true RMS voltmeter across P1A (VCC) and P1B of the front connector. (see Figure 4) 2. Wait 12 minutes to download all GNSS orbital data, or download all the Aiding Data via the AssistNow Online service 3.
EVK-7 / EVK-M8 User Guide 6 Testing Power Save Mode When testing Power Save Mode with 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.

10 Battery replacement To replace the battery (Number 5 in Figure 8), open the unit (unscrew four screws on the front panel). Figure 8: EVK-M8T battery location UBX-14041540 - R04 Early Production Information...
Before shutting down the receiver externally, check the status in MON-HW in field ‘Real Time Clock Status’. Do not shut down the receiver if the RTC is not calibrated. The EVK-M8T does not meet the TTFF specification Make sure the antenna has a good sky view. An obstructed view leads to prolonged startup times. In a well-...

This provides safety, as it is no longer possible to accidentally program a bad configuration (e.g. disabling the main communication port). The EVK-M8T does not work properly when connected with a GNSS simulator When using an EVK together with a GNSS simulator, please pay attention to proper handling of the EVK. A GNSS receiver is designed for real-life use, i.e.
EVK-M8T - User Guide 12 Common evaluation pitfalls • Parameter may have the same name but a different definition. GNSS receivers may have a similar size, price and power consumption but can still have different functionalities (e.g. no support for passive antennas, different temperature range).
