TheĀ Adafruit Feather Bluefruit SenseĀ takes our popularĀ Feather nRF52840 ExpressĀ and adds a smorgasbord of sensors to make a great wireless sensor platform. This Feather microcontroller comes with Bluetooth Low Energy andĀ native USB support featuring the nRF52840!Ā This Feather is an ‘all-in-one’ Arduino-compatible + Bluetooth Low Energy with built-in USB plus battery charging. With native USB it works great with CircuitPython, too.
Like the Feather nRF52840, this chip comes with Arduino IDE support- you can program the nRF52840 chip directly to take full advantage of the Cortex-M4 processor, and then calling into the Nordic SoftDevice radio stack when you need to communicate over BLE. Since the underlying API and peripherals are the same for the ‘832 and ‘840, you can supercharge your older nRF52832 projects with the same exact code, with a single recompile!
This Feather is also aĀ BLE-friendly CircuitPython board! CircuitPython works best with disk drive access, and this is the only BLE-plus-USB-native chip that has the memory to handle running aĀ little Python interpreter. The massive RAM and speedy Cortex M4F chip makeĀ this a good match. Make centrals or peripherals with the ease of CircuitPython.
A chorus of supporting sensors surround the module so you can do all sorts ofĀ environmental and motion-sensing:
- ST Micro series 9-DoFĀ motion –Ā LSM6DS33 Accel/GyroĀ +Ā LIS3MDL magnetometer
- APDS9960 Proximity, Light, Color, and Gesture Sensor
