Adafruit Feather M0 Bluefruit LE
The Feather M0 Bluefruit LE combines an ATSAMD21G18 ARM Cortex M0 processor with a Bluetooth Low Energy module, native USB, and LiPo battery charging. With the power of a 48 MHz ARM core and 256KB of flash, it provides significantly more processing headroom than the 32u4-based Bluefruit while maintaining full BLE functionality.
BLE is supported by all modern smartphones and tablets (iOS, Android, Mac OS X, Windows 8+). The Bluefruit module is built on the Nordic nRF51822 chipset and supports transparent UART serial communication, custom GATT services, HID keyboard emulation, UriBeacon broadcasting, and over-the-air firmware updates.
