Adafruit Feather nRF52840

The Adafruit Feather nRF52840 Express is the new Feather family member with Bluetooth Low Energy and native USB support featuring the nRF52840! It's Adafruits' take on an 'all-in-one' Arduino-compatible + Bluetooth Low Energy with built in USB plus battery charging. This chip has twice the flash, and four times the SRAM of it's earlier sibling, the nRF52832 - 1 MB of FLASH and 256KB of SRAM.

You can program the nRF52840 chip directly using the Arduino IDE 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.

Adafruit have pre-programed the chip with their UF2 bootloader, which can use either commandline UART programming with nrfutil or drag-n-drop mass storage, for CircuitPython installation and also because mass-storage-drive bootloaders make updating firmware so easy. Want to program the chip directly? You can use Adafruits' command line tools with your favorite editor and toolchain.
