ON Semiconductor recently announced the availability of a new Wearable Development Kit (WDK1.0). The kit comprises the following: a touchscreen display; wired and AirFuel-compatible wireless charging capability; a six-axis motion sensor and temperature sensor; an alarm, timer, and stopwatch; schematics; firmware and sample code; a dock station for charging; and a downloadable SmartApp for evaluating and controlling the smartwatches multiple functions.
The WDK1.0’s features, specs, and benefits:
NCP6915 power Management IC provides five LDOs and one DC-DC
NCP1855 battery charger IC, an LC709203F fuel gauge, and a 10-W rated SCY1751 wireless charging front-end controller
MEMS-based FIS1100 IMU, with three‐axis gyroscope and three‐axis accelerometer operation for multidimensional motion tracking
Embedded temperature sensor included and an LC898301 driver IC for initiating haptic feedback
nRF52832 multi-protocol system-on-chip (SoC)
1.44″ 128 × 128 pixel TFT display with a capacitive touch screen
The open-source Puck.js supports both the iBeacon and Eddystone beacon formats and comes with firmware updates for the upcoming Bluetooth v5.0 specification. The circular 35-mm Puck.js has a silicone rubber cover and plastic base. Powered from a CR2032 coin cell battery, the Puck.js includes a magnetometer (digital compass), user-assignable tactile button, and four LEDs (red, green, blue, and infrared).
The Puck.js features an nRF52832 SoC, which means it benefits from a powerful ARM Cortex-M4F processor, 64-MHz clock speed, 64 KB of RAM, 512 KB of flash memory, built-in NFC, over-the-air firmware updates, a 12-bit ADC, timers, an SPI, a temperature sensor, and more.
Nordic Semiconductor recently announced that Arduino’s new Arduino Primo features its nRF52832 Bluetooth low energy SoC. The IoT-targeted Arduino Primo PCB features native Bluetooth low energy wireless connectivity and includes Near Field Communication (NFC), Wi-Fi, and infrared (IR) technologies. In addition to being able to wirelessly connect to a wide array of Bluetooth low energy sensors, the Arduino Primo uses the nRF52832 SoC’s integrated NFC for secure authentication and Touch-to-Pair (a simple BLE pairing function requiring no user interaction), and has embedded IR for traditional remote control.
The Nordic nRF52832 SoC’s ARM processor has ample computational overhead to manage the Arduino Primo’s on-board accelerometer, temperature, humidity, and pressure sensors. The Nordic Semiconductor nRF52832’s features and specs include:
64-MHz, 32-bit ARM Cortex-M4F processor
2.4-GHz multiprotocol radio that’s fully compatible with the Bluetooth 4.2 specification and features –96-dB RX sensitivity and 5.5-mA peak RX/TX currents
512-KB flash memory and 64-KB RAM, and a fully-automatic power management system to optimize power consumption.
You can program via the Arduino Integrated Development Environment (IDE) programming interface. If you want to access the Arduino Prio’s most advanced features and functionality, you can use any Nordic nRF52 Series-compatible Software Development Kit (SDK) or programming tools. For example, the nRF5 SDK for IoT enables you to develop IPv6 over Bluetooth low energy applications on the nRF52832 SoC.
