EVK-NORA-W10 - User guide 1.3 Key features NORA-W10 Open modules, based on SoC Espressif ESP32-S3, 2.4GHz Wi-Fi and Bluetooth® Low Energy, provide: • IEEE 802.11 b/g/n protocol Wi-Fi subsystem • Bluetooth® LE subsystem supporting Bluetooth 5 and Bluetooth mesh • Xtensa® 32-bit LX7 dual core processor up to 240MHz operation •... -
Page 6: Setting Up The Evaluation Board
EVK-NORA-W10 - 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. -
Page 7: Hardware Description
EVK-NORA-W10 - 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 3 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-W10 - 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-W10 - 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 EVK-NORA-W10 - User guide Figure 7: EVK schematic - user buttons Table 1 describes the various user buttons and their relationship with the corresponding GPIO signals and protection diodes shown in Figure 7. For proper operation, the internal pull-up resistor of each NORA-W10 GPIO pin must be enabled.

EVK-NORA-W10 - User guide 3.5 LEDs EVK-NORA-W10 supports eight LEDs: • Power status (D10): Indicates power on the board when lit (green) • UART0 status (D4–D9): Indicates UART0 signal status under GPIO control, as shown in Table • System status (RGB1): Powered by +3V3 and turned on by pulling the associated GPIO low. Disconnect each LED from the GPIO by removing resistors R78–R79, as shown in Table Table 2... -
Page 12: Serial Communication
EVK-NORA-W10 - User guide 3.6 Serial communication The COM port is connected to module UART0 through 1 kΩ resistors, which means that multiple UART0 signals can be connected to pin sockets J3 and J5 at the same time. Table 4 shows the function and COM port connections for each module pin. -
Page 13: Khz Low Frequency Clock
EVK-NORA-W10 - User guide For easy serial communication with the NORA-W10 module, a computer can connect to the evaluation board to provide a single COM port through a single FTDI, USB-to-UART IC, as shown in Figure 11. The CBUS block is not used. Figure 11: FTDI schematic, 1 port default 3.7 32.768 kHz low frequency clock The evaluation board has a 32.768 kHz crystal connected to the NORA-W10 module that allows use... -
Page 14: Jtag Debug Interface
EVK-NORA-W10 - User guide ⚠ Pin 1 of J7 and J8 is connected to GND. To bypass the current sense resistors, RMOD and RIO, solder the respective jumpers JMOD and JRIO. The default hardware configuration does not require any modification of the current-sense headers for the EVK-NORA-W10 to perform properly. -
Page 15: Qspi Memory
EVK-NORA-W10 - User guide Figure 15 shows a schematic diagram of the JTAG debug interface. Figure 15: External JTAG debug interface 3.10 QSPI memory A Quad SPI PSRAM can be optionally mounted on EVK board at U2. The current configuration of NORA-W1 already includes an internal flash memory, so U1 should be left unmounted. -
Page 16: Jumpers
EVK-NORA-W10 - 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 (female) I/O sockets. - Page 17 EVK-NORA-W10 - User guide Table 6 shows the default configuration of “solder-bridge" jumpers. Choose alternative configurations by cutting the bridge and soldering the jumpers in the default positions. Jumper Jumper type Default function Alternate function Solder-bridge Connected to J20 debug connector, JTAG-TMS Cut and close to Test Point GPIO42 Solder-bridge Connected to J20 debug connector, JTAG-TCK Cut and close to Test Point GPIO39 Solder-bridge...
