ItsyBitsy nRF52840 Express Breakout Board

Adafruit ItsyBitsy nRF52840 Express Breakout Board features the Nordic nRF52840 Bluetooth LE processor. The breakout board is a small and powerful, with a fast nRF52840 Cortex M4 processor running at 64MHz and 1MB of Flash. The breakout board is perfect when a user wants something very compact, with a lot of memory and Bluetooth LE support. ItsyBitsy nRF52840 Express is the best option for tiny wireless connectivity, and it can act as both a BLE central and peripheral. The board has support in both Arduino and CircuitPython. The ItsyBitsy nRF52840 Express is only 1.4" long by 0.7" wide but has six power pins and 21 digital GPIO pins (six pins can be analog in). The breakout board has the same chip as the Feather nRF52840, but it is extremely small. It includes 2MB of QSPI Flash built-in, for data logging, file storage, or CircuitPython code.
