1Introduction
The nRFready Smart Remote 3 for nRF52 is a set of hardware and software reference designs providing
a quick and easy starting point for a TV remote control used with Internet-enabled TVs, set-top boxes,
and media players. The reference design consists of a development platform and two product examples.
Providing a single chip solution that is easily implemented, this kit comes complete with source code and
documentation for Bluetooth® Low Energy applications.
The development platform contains three remote controls, one for development and two for demo
purposes.
To obtain The Smart Remote 3 nRF52810 product example (nRF6942), please contact Nordic sales.
1.1 Smart Remote 3 DK add-on
The Smart Remote 3 DK add-on (nRF6932) is a board that allows you to connect to the nRF52
Development Kit (nRF52 DK, not included in this kit). Plugging the DK add-on onto the nRF52 DK gives you
access to the radio components for developing your remote control design.
Based on the nRF52832 multiprotocol System on Chip (SoC), it is optimized for low-power high
performance applications and leverages both Bluetooth Low Energy and 2.4 GHz proprietary protocols.
Note: The Smart Remote 3 DK add-on rev. 1.2 and later is compatible with both nRF51 and nRF52
development kits.
Features:
• Standard remote control keypad
• Motion wakeup detection using low-power accelerometer
• 3D motion tracking using gyroscope and InvenSense® motion library
• Multi-touch trackpad (supports up to five points of contact)
• Voice input using an analog electrostatic microphone (only nRF51)
• Voice input using two digital PDM microphones (only nRF52)
• Infrared LED for legacy support (only nRF52)
• Arduino standard interface for connection to the nRF5x Development Kit
• Optimized power management for low power consumption
1.2 Smart Remote 3 product example for nRF52832
The Smart Remote 3 nRF52 product example (nRF6937) is a fully-designed remote control with audio
input, air mouse functionality, infrared LED, NFC tag, and buzzer. It features a subset of the functionality

of the Smart Remote 3 DK add-on, allowing the board to nicely fit into an almost finished remote control
plastic housing.
Features:
• Standard remote control form factor
• Standard remote control keypad
• nRF52832 QFAA SoC from Nordic
• Voice input using up to two digital PDM microphones, which enable the use of (optional) active noise
reduction algorithms
• 3D motion tracking using gyroscope and InvenSense® motion library
• Motion wakeup detection using low-power accelerometer
•Infrared LED 1
•NFC tag for tap to pair2
• Buzzer for the Find Me service
• Device firmware update (DFU)
• Preprogrammed, can be used out of the box
• Powered by two AA batteries
• SWD interface connector for programming and debugging
• Optimized power management for low power consumption
1.3 Smart Remote 3 product example for nRF52810
The Smart Remote 3 nRF52810 product example (nRF6942) is a cost-optimized remote control with
audio input, air mouse functionality, and infrared LED. It features a subset of the functionality of the
Smart Remote 3 DK add-on, allowing the board to nicely fit into an almost finished remote control plastic
housing.
nRF52810 support starts from firmware rev. 1.2.
Features:
• Standard remote control form factor
• Standard remote control keypad
• nRF52810-QFAA SoC from Nordic
• Voice input using one digital PDM microphone
• 3D motion tracking using gyroscope and InvenSense motion library
• Motion wakeup detection using low-power accelerometer
• Infrared LED
• Device firmware update (DFU)
• Preprogrammed, can be used out of the box
• Powered by two AA batteries
• SWD interface connector for programming and debugging
• Optimized power management for low power consumption
Because of modular firmware, the feature set can be configured. It is possible to add some features
present in the nRF52832 version of the firmware while removing others from the nRF52810 version to
make sure there is enough memory. For more information, see firmware documentation available in a
folder on your computer after you have run the installer file.
To obtain The Smart Remote 3 nRF52810 product example (nRF6942), please contact Nordic sales.
