The following sections describe different jumper configurations and power scenarios that is available on the board, including the default configuration.

⚠ Check the jumper positions carefully; if a jumper is connected in a wrong way, it can permanently

damage the components that are on or connected to the board.

1.6.2 Default power, 3.3 V

This is the default power configuration for the evaluation board, and the jumpers are installed out of the box with this power configuration. All board peripherals are powered up, the NINA module is directly supplied by the board and everything is running at 3.3 V.

1.6.3 Battery powered, 3 V

When using a battery, Figure 7 shows the default configuration. The battery voltage is connected to VDD_NINA, which in turn, is connected to the NINA-B3 VCC supply. If needed, a jumper can be added to J22 pins 2 and 4 to supply LEDs and other peripherals with power, as long as this does not exceed the maximum current rating of the battery. If the NINA module has to be configured, the VDD_MCU net can be connected to enable PC communications by adding a jumper to J7 pins 9 and 10.

1.6.4 Battery powered with protection diode, 2.7 V

This use case is meant to protect the battery from current back surges. When using the NFC interface, there is a risk that the applied electromagnetic field can cause back surges that will typically damage a non-chargeable battery. To prevent this damage, a schottky diode can be added in series to the battery, which will block any back current surges. A jumper should then be added to J7 pins - 3 and 4 instead of 5 and 6.

The diode will lower the voltage level of the battery by about 0.3 V.

(Optional) Powers up the peripherals directly connected to NINA such as LEDs and external memory with the NINA supply voltage.

1.6.5 External supply

When measuring current consumption or performing other NINA-B3 module characterization measurements, it can be useful to power the module with an external source such as a DC power analyzer. In such a case, all jumpers can be removed and the required supply nets can be fed externally by connecting to the pin headers. For example, the NINA-B3 module can be powered by connecting an external supply directly to the J22 pin 1 and GND.

☞ Take care that unpowered parts of the board are properly isolated. If a voltage is applied to the

signal of an unpowered device, current might leak through various protection circuits of the device. This might give false readings when measuring current consumption etc.

Figure 9 below shows a few optional jumper connections that can be helpful when supplying the module with an external supply.

1.6.6 Raspberry Pi HAT

When connecting a HAT to the Raspberry Pi interface, the following jumper configuration can be used. Depending on how the NINA module should communicate with a test PC over USB or with the HAT, the VDD_MCU net could be left unpowered.

⚠ The 3V3_PI supply net must only be powered when connecting to a Raspberry Pi expansion board

(HAT). If connecting to a Raspberry Pi board, the jumper must be disconnected.

EVK-NINA-B3 - User Guide

1.7.1 Arduino shield compatibility

The EVK-NINA-B3 has an I/O voltage range of 1.7-3.6 V. It can therefore be used only with shields that also support an I/O voltage within this range.

The EVK-NINA-B3 has a pinout that is compatible with some Arduino or Arduino inspired shields. This section describes the features of the EVK pins that a shield must comply with:

• IOREF: The I/O voltage level of the NINA-B3 module is 3.3 V by default, but the EVK can be modified to allow other voltages (1.7-3.6 V).

• RESET: Is connected to the RESET button (SW0).

• 3.3 V: A regulated 3.3 V output. Should not be used as a voltage supply input, use the VIN pin

instead.

• 5 V: Is only a 5 V supply output if the EVK is being powered by USB. If any other power configuration is used, this pin will be unconnected (floating). It is safe to connect an external 5 V supply to this pin even when a USB cable is connected. This pin cannot be used to power the board, use the VIN pin instead.

• VIN: May be used as a 5 -12 V supply input to power the EVK-NINA-B3.

• Pin 0 (RX): Is connected to the NINA-B3 UART RX pin (NINA pin 23).

• Pin 1 (TX): Is connected to the NINA-B3 UART TX pin (NINA pin 22).

Note on SCL/SDA: On some Arduino boards, the I

2

C signals, SCL, and SDA are connected to the pins A4 and A5 and to the SCL and SDA pins in the top right hand corner. Since these pins will be shorted together it might cause problems when connected to the EVK-NINA-B3, which has not shorted these pins together.

Note on digital I/O pins: Some of the digital I/O pins can be connected to the on-board debug MCU, thus allowing serial communication and flashing/debugging over USB. This can cause interference on the signals that are also used by an Arduino shield. See section 1.10 on how to disconnect these signals from the debug MCU.

1.8 Raspberry Pi compatible interface

The EVK-NINA-B3 includes a 40-pin GPIO header that can be used to interface with either a Raspberry Pi computer board or with a Raspberry Pi expansion board (HAT). The EVK-NINA-B3 uses different hardware and software configurations depending on if it is connected to a Pi or a HAT; the differences are covered in this section. The default configuration is to connect to a Pi.

Not all the Raspberry Pi versions and HATs are supported, since it requires the 40-pin GPIO header, which older versions did not have. Table 9 lists the compatible Raspberry Pi versions.

There are two voltage nets used in the Raspberry Pi interface - 3V3_PI and 5V. Both the 3V3_PI and 5V nets can be used to power HATs, but should not be used when connecting to a Raspberry Pi. See section 1.6.6 for more information.

⚠ The 3V3_PI power net must not be connected to the 3.3 V supply when connected to a Raspberry

Pi board. It could damage both the boards.

1.8.2 UART

The Raspberry Pi interface provides two pins that can be used for UART communications GPIO14 and GPIO15. In UART communications, signals are always connected RX <-> TX and vice versa. This means

that on a Raspberry Pi board GPIO14 will be TX and on a HAT it will be RX. To support talking to both HATs and Pi boards, the zero Ω resistors - R57, R58, R59 and R60 can be used to toggle the NINA TX and RX pins between GPIO14 and GPIO15. If a NINA-B30 is used, this switch can also be made in the software. By default, the EVK-NINA-B3 will be configured to simulate a HAT, and GPIO14 is connected to the NINA UART_RXD pin and GPIO15 is connected to the NINA UART_TXD pin.

1.8.3 EEPROM support

The Raspberry Pi interface supports a unique EEPROM solution to store the HAT specific GPIO configurations on the HAT board, to be read by the Raspberry Pi before configuring its GPIOs. The two pins used for this - ID_SD and ID_SC, are connected to the NINA-B3 module. The NINA module can thus either read the GPIO configuration from a HAT, or simulate an EEPROM and send configurations to a connected Pi. This requires a NINA-B30 module and a custom built application.

It is not mandatory to use this EEPROM solution; if not used, the two NINA pins GPIO_42 and GPIO_41 can be left unconfigured.

Two pull-up resistors - R44 and R50, can be added to the I the evaluation board by default.

Visit https://github.com/raspberrypi/hats/blob/master/designguide.md for more information on the ID EEPROM specification.

1.10 Disconnecting NINA signals from board peripherals

All evaluation board peripherals, such as level shifters, LEDs, and the interface MCU will be connected to the NINA-B3 module by default. This might not suit all evaluation scenarios. All peripherals can be switched off by disconnecting their power supplies (see section 1.6), but if only specific signals have to be isolated, it will require finer control. All the NINA module signals that are connected to board peripherals have thus been routed via jumper headers, so that jumpers can be pulled or added as needed by the evaluation board user, isolating, or connecting specific signals. Figure 14 shows the layout of these jumper headers.

1.11 Software debug options

You can debug the software using the following two options in EVK-NINA-B3:

• Onboard debug solution available on the USB connector

• Using an external debugger connected to J12 connector

An external debugger connected to the J12 connector is useful when powering the evaluation board with the CR2032 coin cell battery, or through the external power supply connector J5. It could also be useful in a scenario where the debug MCU interface has been disconnected from the NINA-B3 module using the jumpers on J9 header. The SEGGER J-Link software [4] is required to debug using the onboard J-Link hardware on the EVK-NINA-B3.

2 Setting up the evaluation board

2.1 Evaluation board setup

The EVK-NINA-B311/EVK-NINA-B312 will be delivered with the u-blox connectivity software installed on the module. Before connecting the module, download and install the latest u-blox s-center evaluation software from the u-blox website.

To use Bluetooth Low Energy on the EVK-NINA-B311/EVK-NINA-B301, connect a 2.4 GHz antenna to the U.FL antenna connector (J10). The EVK-NINA-B312/EVK-NINA-B302 has an onboard antenna.

Plug in either an external power supply in J5 connector or connect to a USB host with a USB cable attached to J8 connector. You can also power the evaluation board with a CR2032 coin cell battery. The status light (DS6) will turn green, indicating it has power. The NFC antenna can be connected to the J11 connector.

⚠ Be careful to check polarity before connecting an external power supply to the EVK-NINA-B3

evaluation board. Center conductor is positive (+) and the ring is negative (-).

The operating system will install the correct drivers automatically. The drivers will only need to be installed the first time you connect the unit to a new computer.

⚠ If the drivers are not installed automatically, download the nRFgo Studio from

www.nordicsemi.com to get the Jlink CDC UART driver.

A COM port will automatically be assigned to the unit by Windows. Do the following to view the assigned COM ports on Windows 7:

• Open the Control Panel and click Hardware and Sound.

• Click Device Manager in Devices and Printers. This will open Device Manager window where you

can view the assigned COM ports.

To view the assigned COM ports on Windows 10, right-click on the Windows Start button and select Device Manager.

2.2 Starting up

2.2.1 EVK-NINA-B311 and EVK-NINA-B312
