Before you start, check Minimum requirements on page 5. Connect the Dongle to a computer and get started with nRF Connect for Desktop. 1. Download and install nRF Connect for Desktop. This includes the driver for the nRF52840 USB Device Firmware Upgrade (DFU) feature. For documentation on the tool, see nRF Connect. 2. Insert the nRF52840 Dongle in a USB port on your computer. The status light (LD2) starts pulsing red, indicating that the Dongle is powered up and is in bootloader mode. After a few seconds, the computer will recognize the Dongle as a USB composite device. The driver needed for the nRF52840 USB DFU feature is also installed. 3. Optional: Download the nRF5 SDK. nRF5 SDK contains application examples for the Dongle. For documentation, see nRF5 SDK v15.0.0. 4. Optional: Download SEGGER Embedded Studio (SES). SES is needed for building application examples for the Dongle. It can be used free of charge with nRF devices. 5. Optional: Install nrfutil. nrfutil can be used for programming the Dongle from the command line. 6. Open an nRF Connect for Desktop app and select the serial number of the nRF52840 Dongle as the target. Applications that support the nRF52840 Dongle will display the serial numbers of any connected Dongles in the device drop-down list. If the app supports the Dongle but the correct firmware is missing, you will be asked to confirm that you want to have the Dongle programmed. Click OK. If the Dongle contains the correct firmware, the app will start immediately. 4440_052 v1.0 8 5 Programming The nRF52840 Dongle can be programmed through the built-in USB bootloader. Before you start, check Getting started on page 8. To program the Dongle, it must be in bootloader mode. The Dongle can be made to enter bootloader mode in one of the two ways: • Trigger the nRF52840 USB DFU endpoint. The firmware to support this is embedded in all nRF Connect for Desktop apps for the nRF52840 Dongle. If you add the DFU Trigger Library (USB) to your custom device firmware, you will be able to trigger the DFU from nRF Connect for Desktop without using any buttons. For documentation, see DFU Trigger Library (USB), which is part of the nRF5 SDK v15.0.0. • For Dongles with applications missing the USB DFU endpoint: Press the RESET button. When the nRF52840 Dongle has entered the bootloader mode, LD2 pulses red. The Dongle is now ready for programming. All the nRF Connect for Desktop apps require specific firmware to be present on the nRF52840 Dongle to function correctly. The apps will update the firmware if needed. If you want to upload a custom firmware to the Dongle, you can do this by using the dedicated Programmer programming app, or nrfutil. 4440_052 v1.0 9 6 Hardware description The nRF52840 Dongle can be used as a development platform for the nRF52840 SoC. It features user configurable LEDs and a button as well as multiple GPIOs available along the board edges. In addition to radio communication, the nRF5240 SoC can communicate with a computer through USB. 6.1 Hardware drawings The nRF52840 Dongle hardware drawings show both sides of the PCA10059 board. Figure 3: nRF52840 Dongle (PCA10059) front view Figure 4: nRF52840 Dongle (PCA10059) back view 6.2 Block diagram The block diagram illustrates the nRF52840 Dongle functional architecture. 4440_052 v1.0 10 Hardware description LEDs Button GPIO Reset Antenna USB nRF52840 Matching network Debug Osc 32768 kHz Osc 32 MHz Figure 5: Block diagram 6.3 Power supply The nRF52840 Dongle can be powered from different sources. 6.3.1 Internal regulator The default power supply of the nRF52840 Dongle is the USB interface. The USB interface supplies power to the on-chip high voltage regulator of the nRF52840 SoC. The output of the regulator supplies the SoC and the LEDs. The USB power connection (VBUS) is also available along the board edge. Next to VBUS, there is a connection point for VDD OUT, which is the output of the nRF52840 SoC high voltage regulator. For maximum power draw from this pad, see nRF52840 Product Specification, and take into account the power draw of the onboard nRF52840 and the LEDs. Figure 6: USB power connection (VBUS) and SoC high voltage regulator output (VDD OUT) By using the on-chip high voltage regulator, the VDD voltage level can be set in the REGOUT0 register in UICR. See nRF52840 Product Specification. 4440_052 v1.0 11 Hardware description 6.3.2 External regulated source The nRF52840 Dongle can also be configured to be supplied from an external regulated 1.8–3.6 V source through the VDD OUT connection point. To enable this, SB2 must be cut and SB1 must be soldered. CAUTION: Do not have both SB1 and SB2 connected at the same time as this will damage the nRF52840 SoC. Figure 7: Configuring 1.8-3.6 V external source 6.4 Buttons and LEDs The nRF528540 Dongle is equipped with a green LED (LD1), a multicolor RGB LED (LD2), a user configurable button (SW1), and a reset button (SW2). The LEDs and buttons are connected to dedicated I/Os on the nRF52840 SoC. Figure 8: nRF52840 Dongle buttons and LEDs 4440_052 v1.0 12 Hardware description Part Description GPIO SW1 Button P1.06 SW2 Reset P0.181 LD1 Green P0.06 LD2 Red P0.08 LD2 Green P1.09 LD2 Blue P0.12 Table 1: LED connections The buttons are active low, which means that the input will be connected to ground when the button is activated. The SW1 button has no external pull-up resistor, but the reset button (SW2) has a 10 k pull-up resistor. To use SW1, P1.06 must be configured as an input with an internal pull-up resistor. The LEDs are active low, which means that writing a logical zero '0' to the output pin will illuminate the LED. 6.5 32.768 kHz crystal The nRF52840 Dongle is equipped with a 32.768 kHz crystal (X2) for high accuracy and low average power consumption. Note: The 32.768 kHz crystal (X2) is required for correct operation when using ANT/ANT+. 6.6 USB The nRF52840 Dongle features a USB-A-type connector printed on the circuit board. Additional test points for the USB data lines are available on the bottom side of the circuit board if the nRF52840 Dongle is used as a module on a motherboard with a USB connector. To disconnect data lines from the onboard USB connector, cut solder bridges SB3 and SB4. Figure 9: Disconnecting USB data lines 1 SW2 is also connected to P0.19, P0.21, P0.23, and P0.25. This is done to simplify PCB routing. These GPIOs should not be used and should be left as input with no pull or be disconnected by firmware. 4440_052 v1.0 13 Hardware description 6.7 SWD interface On the back side of the nRF52840 Dongle, there are connection points for the SWD interface. The dongle is equipped with a footprint for two different connectors. On footprint P1, a standard 2×5-pin pin header with a 1.27 mm pitch can be soldered. On footprint J2, it is possible to connect a TC2050 cable from Tag-Connect. Figure 10: SWD interface connectors For instance, a Nordic development kit can be used as a programmer for the Dongle. 6.8 External connections The nRF52840 Dongle has 15 GPIOs in addition to the ground, power, and SWD connections along the castellated edges. The castellated edge holes have a pitch of 0.1 inches (2.54 mm) and a row spacing of 0.6 inches (15.24 mm)2, making it suitable for stripboard connection. Test points for additional nine GPIOs are available on the back side of the circuit board, leaving a total of 24 GPIOs accessible. Note: There is no reverse voltage protection on the power connections. 2 The SWD connections are located 0.2 inches (5.08 mm) away from the GPIOs with a row spacing of 0.4 inches (10.16 mm) 4440_052 v1.0 14 Legal notices By using this documentation you agree to our terms and conditions of use.
