Adafruit Feather Bluefruit wireless sensor board soon available




Adafruit has today announced the Adafruit Feather Bluefruit Sense development board will be soon arriving in their online store, building on the popular Feather nRF52840 Express, by adding a range of sensors that can be accessed wirelessly. The Feather microcontroller is equipped with Bluetooth Low Energy connectivity together with native USB support featuring the nRF52840. Offering an ‘all-in-one’ Arduino compatible mini development board, supporting CircuitPython. Adafruit explains a little more :

“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 a 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 a the little Python interpreter. The massive RAM and speedy Cortex M4F chip makes this a good match.”

Unfortunately, no information on pricing has been released as yet by Adafruit, but if you’re interested in receiving an update when the development board becomes available jump over to the online store via the link below to register your details.
