Introduction
The nRFready Smart Remote 3 for nRF52 reference design (nRF6939) is a high-performance development
platform providing a quick and easy starting point for TV remote control used with Internet-enabled TVs,
set-top boxes, and media players. Providing a single chip solution that is easily implemented, this kit comes
complete with source code and documentation for Bluetooth
®
low energy applications.
This reference design contains two remote controls, one for development and another for demo purposes.
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.
Important: 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 nRF52 product example
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
