Feather of the Day: Adafruit Feather nRF52840 Express #Bluetooth #Adafruit #Feather

The Adafruit Feather ecosystem is so rich with hardware diversity, we wanted to share them, one each day. Today is the Adafruit Feather nRF52840 Express!

The Adafruit Feather nRF52840 Express has Bluetooth Low Energy and native USB support featuring the nRF52840!  It’s our take on an ‘all-in-one’ Arduino-compatible + Bluetooth Low Energy with built-in USB plus battery charging. With native USB it’s even ready to join the CircuitPython party. We have other boards in the Feather family, check’em out here.

This chip has twice the flash, and four times the SRAM of its earlier sibling, the nRF52832 – 1 MB of FLASH and 256KB of SRAM. Compared to the nRF51, this board has 4-8 times more of everything.

For this chip, we’ve added 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.

We’ve also chosen this chip for our first 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 little Python interpreter. The massive RAM and speedy Cortex M4F chip make this a good match.

It’s got tons of awesome peripherals: plenty of GPIO, analog inputs, PWM, timers, etc. Best of all, it’s got that native USB! Finally, no need for a separate USB serial chip like CP2104 or FT232. Serial is handled as a USB CDC descriptor, and the chip can act like a keyboard, mouse, MIDI device, or even disk drive. This chip has TinyUSB support – that means you can use it with Arduino as a native USB device and act as UART (CDC), HID, Mass Storage, MIDI, and more!
