Page 5: Product Description
Because of the integrated antennas in the SAM-M10Q module, the standard u-blox GNSS EVK aluminum box cannot be used for the EVK-M10QSAM. A plastic cap is attached on the top of the antenna module in EVK-M10QSAM. The purpose of the cap is to prevent air flow inside the SAM-M10Q shield. -
Page 6: Specifications
Table 2: EVK-M10QSAM specifications 2.1 Safety precautions EVK-M10QSAM must be supplied by a PS1 class limited power source. See section 6.2.2.4 of IEC 62368-1:2018 [3] for more information on the PS1 class. In addition to a limited power source, only ES1 class circuits are to be connected to the EVK- M10QSAM, including interfaces and antennas. -
Page 7: Getting Started
2, the u-blox interactive evaluation software tool is required for configuration, testing, visualization and data analysis of u-blox GNSS receivers as well as EVKs. The EVK user guide together with the u-center 2 evaluation tool provide useful assistance during all phases of a system integration project. -
Page 8: Device Description
Figure 4.1 Interface connection The EVK-M10QSAM supports UART and I2C communication interfaces. To connect the EVK to a PC, use a standard SUBD-9 cable or the included USB cable depending on the interface in use. The EVK also includes an on-board USB-to-Serial converter for USB-to-UART communication with the receiver. -
Page 9: Interface Switch
4.1.2 14-pin connector The EVK-M10QSAM front side has a 14-pin connector that provides programmable input/output signals, communication interfaces and supply options. All these pins are ESD protected. The 14-pin connector can be used for communicating with the receiver through the UART and I2C interfaces. -
Page 10: Usb
The USB connector in the evaluation kit can be used for both power supply and communication. The easiest way to evaluate the EVK-M10QSAM operation is to connect the EVK to a PC with the USB cable and then to use the u-center 2 tool to configure and monitor the GNSS functions. The USB connector is internally connected to a USB-to-Serial converter that connects to the UART interface of the u-blox M10 receiver on the EVK. -
Page 11: I2C
External antenna connectivity through SMA connector is not available in the EVK-M10QSAM. 4.3 Time pulse u-blox receivers include a time pulse function that provides pulses with a configurable pulse period, pulse length and polarity (rising or falling edge). The u-center 2 evaluation tool can be used to configure the time pulse parameters. -
Page 12: Safe Boot Button
This button is used to set the receiver into safeboot mode. In this mode, the receiver executes only the minimal functionality. The safeboot mode is not recommended in EVK-M10QSAM because the u-blox M10 receiver is using a ROM-based firmware and thus, it is not necessary to go into safe boot mode. -
Page 13: Measuring Current
AssistNow ™ Online service. On EVK-M10QSAM, the main supply voltage for the u-blox M10 GNSS receiver is 3.3 V. To measure the total GNSS supply current with EVK-M10QSAM, follow these steps: Power up EVK-M10QSAM. -

If other configuration keys were set after, these will not be applied. Therefore, the new baud rate needs to be selected manually to resume communication and apply the remaining configuration items. -
Page 21: Navigation Update Rate
Figure 14: EVK-M10QSAM receiver navigation update rate configuration 9.4 Power modes EVK-M10QSAM supports the following power modes and can be configured with the CFG-PM- OPERATEMODE configuration key. • Continuous mode (FULL): This is the full power mode and the default mode of the receiver. No power save mode is active in this mode. -
Page 22: Backup Modes
• Hardware backup mode: In this mode, other supplies except the backup supply (V_BCKP) are turned off. On the EVK-M10QSAM, this is achieved by turning off the main power supply of the EVK either by removing the USB cable or the 5.0 V supply from the 14-pin connector. -
Page 23: Troubleshooting
The maximum baud rate of 921600 or 460800 baud rate should be sufficient for most use cases. If the baud rate is insufficient, GNSS receivers based on u-blox M10 GNSS technology will skip excessive messages. Some serial port cards/adapters (e.g. USB to RS-232 converter) frequently generate errors. - Page 24 EVK-M10QSAM does not work properly when connected to a GNSS simulator When using EVK-M10QSAM 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. time is always moving forward).

EVK-M10QSAM - User guide 11 Common evaluation pitfalls • Parameters 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). Also, the definitions of Hot, Warm, and Cold Start times may differ between suppliers. -
