Lightweight Board Delivers Efficient BLE and Arduino Compatibility for Wearables
Mouser Electronics, Inc. is now stocking the Feather nRF52 Bluefruit from Adafruit. The Feather nRF52 Bluefruit, part of Adafruit’s Feather line of standalone and stackable development boards, is a complete Arduino-compatible, Bluetooth low energy development board with built-in USB and battery charging. Using the powerful onboard Nordic system-on-chip (SoC), engineers and makers can run code directly on the board without requiring an external microcontroller, which improves performance and power consumption for a variety of Internet of Things (IoT), wearables, lighting, MIDI audio, and other applications.
The Adafruit Feather nRF52 Bluefruit, available from Mouser Electronics, improves on previous nRF51-based Bluefruit modules with double the flash memory, SRAM, and performance plus native support for the Arduino integrated development platform (IDE). The Feather incorporates a Nordic nRF52 SoC, which is built around a 32-bit Arm Cortex M4F processor with 512 KBytes of flash and 64 KBytes of RAM. The SoC’s embedded 2.4 GHz transceiver offers transmit power up to 4 dBm and receiver sensitivity of -96 dBm in Bluetooth low energy mode.
The board offers a range of peripherals, including 19 general-purpose inputs and outputs (GPIOs), eight analog inputs, and three 4-output PWM modules. A built-in USB-to-serial converter enables quick programming and debugging, and a standard lithium polymer battery connector provides onboard USB-based battery charging. True to its name, the 51 × 23 × 8 mm board weighs just 5.7 grams without headers and works with almost any Adafruit FeatherWings board that doesn’t require UART.
