2.1 nRF module connectors

To utilize the features of the nRFgo Starter Kit a nRFgo compatible Development Kit module (sold

separately) must be inserted into the nRF module socket (see Figure 2.).

Figure 3. nRF module connectors

Note: Do not apply too much pressure on the antenna end of your nRFgo Development Kit module

when inserting it into the nRFgo Motherboard, as this may distort the pins in the nRFgo

Motherboard connectors. When removing, pull the module straight up.

Table 1. Description of the nRF module connectors pins

The pinout of each of the generic ports will change depending on which device is present on the nRFgo

Development Kit module. Please refer to the nRF device’s Development Kit User Guide for pinout details

on the nRF device ports (pins 7 to 14 and 29 to 36).

2.2 Power supply

The Motherboard can be powered from three sources:

• From USB while connected to a PC

• External power supply with the following specifications:

• AC or DC

• 8-20 V, min 500 mA.

• 2.1mm center pin, with any polarity

• Batteries, 3 x AAA 1.5 V. Do not use rechargeable batteries.

The S9 switch is the main power switch. You can turn on and off the power to the nRFgo Motherboard

using this switch.

Using switch S8 you can select whether power to the Motherboard should be sourced from VBUS in the

USB connector, or if power should be sourced from the external power supply connector J3.

Revision 1.5

nRFgo Starter Kit User Guide

The 3xAAA battery pack supplies the board if neither external power supply options are present. When

using batteries the S9 switch is still the main power switch, but setting the S8 switch is no longer relevant.

The regulated supplies on the nRFgo Motherboard can supply a total of 500 mA. When external

application circuitry is connected, ensure that the current drain does not exceed this limit. If USB is used as

the power supply to the system, ensure that the USB port is capable of delivering 500mA or use an

externally powered USB hub.

2.2.1 Regulated supplies

The nRFgo Motherboard has three separate power nets: VTG, VCC and VEXT.

VTG: Vtarget is the power supply for the nRFgo Development Kit module. This is a variable power supply,

controlled from nRFgo Studio PC software available from www.nordicsemi.com. The VTG is split into two

branches; VTG and VTG_nRF. VTG_nRF is split from VTG and routed through the nRF current

measurement header P7. On the nRFgo Development Kit modules VTG_nRF supplies only the nRF

devices. Any non Nordic Semiconductor circuitry is supplied from VTG. This arrangement enables ‘nRF

device(s) only’ current consumption measurements on P7.

VCC: VCC is a fixed 3.8 V supply mainly for the nRFgo Motherboard control circuitry. It is available in the

nRF module connectors and more importantly in the extension board connectors for development

flexibility.

VEXT: VEXT supplies the signal level shifters and circuitry/headers directly interfacing the nRF module.

VEXT on the nRFgo Motherboard is sourced from the nRFgo Development Kit module to ensure correct

signal levels interfacing it. In most cases the connector pins VTG and VEXT are shorted on the nRF

Module resulting in VEXT=VTG. Please refer to the nRFgo Development Kit User Guides for details.

2.2.2 Status LEDs

The nRFgo Motherboard has two LEDs indicating power supply status:

• D9 is lit if VCC is present.

• D8 is green if VTG is present.

2.3 Status display

When nRFgo Studio is running on a computer and the Motherboard is connected to that computer, the

LED status display shows the ID number assigned to the nRFgo Motherboard by nRFgo Studio. The same

ID will be shown in the nRFgo Studio user interfaces. If two or more nRFgo Motherboards are connected to

one PC, make sure the ID number in the nRFgo Studio user interface matches the ID on the nRFgo

Motherboard you want to control.

If you unplug the USB cable linking the Motherboard to the PC, and the board is fitted with batteries, the ID

number assigned to the Motherboard will begin to flash intermittently with a dot (.), this signals that the

Motherboard’s ID may change in nRFgo Studio when the Motherboard is reconnected to the PC.

2.4 nRF reset button

The nRF RESET button is the reset button for the nRFgo Development Kit module connected to MODA/

MODB. Pressing this button causes a full reset of the Development Kit module, but it does not affect the

nRFgo Motherboard’s main MCU.
