Page 6: Setting Up The Evaluation Board
EVK-NORA-W1 - User guide Setting up the evaluation board The EVK-NORA-W10 is delivered without any software (open CPU) and the software must be developed by the user. The following devices are applicable: • EVK-NORA-W101 • EVK-NORA-W106 Connect the external power supply to the EVK as described in Powering the board. -

EVK-NORA-W1 - User guide Hardware description ☞ Design files for the EVK-NORA-W10 PCB are available from your local u-blox support team. 3.1 Overview Figure 2 shows the physical location of the power switch, supported IO signals, LEDs, buttons, and connectors on the EVK-NORA-W10 board. -
Page 8: Powering The Board
EVK-NORA-W1 - User guide ⚠ Only if the power protection circuits are left intact can the USB be safely connected at the same time as external power. This makes programming of the module easier. ⚠ The EVK USB type C connectors are only capable of handling 5 V input, 12 V is not allowed. 3.2.1 Powering the board Set the power switch (SW6) “ON”... -
Page 9: Reset
EVK-NORA-W1 - User guide 3.3 Reset EVK-NORA-W10 provides a hardware reset to the NORA-W10 module. The Reset button (SW5) is connected to the module RESETn signal. To enter bootloader mode, hold down the Boot button (SW2) during the USB power on. To enter the programming mode, assert a reset in bootloader mode. -
Page 10: Buttons
EVK-NORA-W1 - User guide 3.4 Buttons In addition to the RESET button, the evaluation board also supports four user buttons that are active- low and connect to ground when pressed. The functionality of these buttons is controlled by the system software through the GPIO interface. The buttons and the associated GPIO signals are shown Figure ☞... -

Page 14: Current Sensing Headers
EVK-NORA-W1 - User guide If the signals GPIO15/ADC2-CH4 and GPIO16/ADC2-CH5 are used, the crystal can be removed from the circuit by opening jumpers J19 and J21 and soldering across the normally open positions, as shown in Figure 12. This connects XT-32k-p and XT-32k-n to the EVK pin socket J2, pin 5 and pin 6. See also GPIO jumpers. -

EVK-NORA-W1 - User guide 3.9 External JTAG debug interface External target hardware can be attached to the J20 header connector for firmware programming and debug. J20 is implemented with a 2x5 header with 1.27 mm pitch. Figure 13 shows the physical layout of connector. -
Page 16: Qspi Memory
EVK-NORA-W1 - User guide 3.10 QSPI memory A Quad SPI PSRAM can be optionally mounted on EVK board at U2. The present configuration of NORA-W1 already includes an internal flash memory, so U1 should be left unmounted. PSRAM can be powered from +3V3 or internal VDD-SPI supplies in the module internal. Include either resistor R70 or R71 to select the preferred choice of power supply to the SPI flash memory chip. -
Page 17: Jumpers
EVK-NORA-W1 - User guide 3.11 Jumpers The EVK-NORA-W10 printed circuit board (PCB) supports several solder-bridge jumpers for configuring GPIO functions. Most jumpers disconnect on-board components from the GPIO nets and subsequently eliminate interference generated by any external circuits attached to the I/O sockets (female). -
