Page 6: Product Description
EVK aluminum box cannot be used for the EVK-M8QCAM and EVK-M8CCAM. A plastic cap is attached on the top of the antenna module in EVK-M8QCAM and EVK-M8CCAM. The purpose of the cap is to prevent air flowing inside the CAM-M8Q and CAM-M8C shield. -
Page 7: Specifications
Table 2: EVK-M8QCAM and EVK-M8CCAM specifications 2.1 Safety precautions EVK-M8QCAM and EVK-M8CCAM must be supplied by an external limited power source in compliance with clause 2.5 of the standard IEC 60950-1. In addition to the external limited power source, only separated or Safety Extra-Low Voltage (SELV) circuits are to be connected to the evaluation kit, including interfaces and antennas. -
Page 8: Getting Started
Once the zip file is downloaded, unzip the file in the Tools folder and double-click the extracted exe file. The software components will be installed on your system and placed under the “u-blox” folder in the “Start Programs” menu. -
Page 9: Device Description
The CAM-M8Q or CAM-M8C module is embedded with a chip antenna. Additionally, an active GPS / GLONASS / Galileo / BeiDou antenna with 3 m cable is included in the EVK-M8QCAM or EVK-M8CCAM evaluation kit. It is possible to connect external antenna signals of various active GPS / GLONASS / Galileo / BeiDou antennas to the EVK-M8QCAM/M8CCAM evaluation unit through SMA connector. -
Page 10: Antenna Connector
4.3.1 Antenna connector An SMA female jack is available on the rear side (see Figure 2) of the EVK-M8QCAM/M8CCAM evaluation unit for connection with external antenna signals. DC voltage at the RF input is 3.3 V. The internal short circuit protection limits the maximum current to 60 mA. -
Page 11: Rst Button
EVK-M8CAM User Guide 4.3.5 RST button The RST button on the front side resets the unit. To avoid an inadvertent reset, the button is recessed. 4.3.6 Safe boot button This is used to set the unit into safe boot mode. In this mode, the receiver executes only the minimal functionality. -

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 / u-blox M8 Receiver Description including Protocol Specification [3]. -
Page 13: Measuring Tracking Current
EVK-M8CAM User Guide 5 Measuring the tracking current To measure the tracking current with the EVK-M8QCAM or EVK-M8CCAM, follow these steps: 1. Connect a true RMS voltmeter across P1A (VCC) and P1B of the front connector (see Figure 5). 2. Wait 12 minutes to download all of the GNSS orbital data, or download all the Aiding Data via the AssistNow Online service. -

Page 20: Troubleshooting
After installing the USB driver for the first time by connecting EVK-M8QCAM/M8CCAM to the PC with USB cable, the cursor on the PC starts to jump around the screen The syndrome is caused when the NMEA 0183 GNSS serial data is misinterpreted as mouse data by the serial port enumerator (serenum.sys), resulting in erratic mouse cursor activity. - Page 21 The EVK-M8QCAM/M8CCAM does not preserve the configuration when power is cut off u-blox M8 GNSS technology uses a slightly different concept than most other GNSS receivers do. Settings are initially stored to volatile memory. In order to save them permanently, sending a second command is required.

Page 22: Common Evaluation Pitfalls
EVK-M8xCAM - User Guide 11 Common evaluation pitfalls A 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). -
