Description:
The Adafruit Feather nRF52840 Sense is a comprehensive development board that integrates the powerful nRF52840 microcontroller with a suite of onboard sensors, creating an ideal platform for wireless sensing applications. Operating at 64 MHz, the ARM Cortex M4F processor is complemented by 1 MB of flash memory and 256 KB of SRAM, providing ample resources for complex projects. The board supports Bluetooth Low Energy (BLE) and features native USB functionality, facilitating seamless connectivity and programming. Its compact Feather form factor ensures compatibility with a wide range of FeatherWing add-ons, enhancing its versatility for various development needs.
Equipped with multiple sensors, the Feather nRF52840 Sense enables comprehensive environmental and motion-sensing capabilities. It includes a 9-DoF motion sensor (LSM6DS3TR-C accelerometer/gyroscope and LIS3MDL magnetometer), an APDS9960 sensor for proximity, light, color, and gesture detection, a PDM microphone for sound input, an SHT humidity sensor, and a BMP280 sensor for temperature and barometric pressure measurements. This extensive sensor array, combined with BLE connectivity and native USB support, makes the board particularly suitable for Internet of Things (IoT) projects, wearable technology, and interactive applications requiring real-time data acquisition and wireless communication.
