ADAFRUIT INDUSTRIES ADAFRUIT Feather M0 Bluefruit LE MCU Development Board 2995

ADAFRUIT INDUSTRIES MCU Development Board

The ADAFRUIT INDUSTRIES MCU development board has all the basic features shared by all the Feather M0 range boards with a built-in Bluetooth low energy module (BLE). It uses the Bluefruit LE module and has two status indicator LEDs. It has an nRF51822 chipset from Nordic Semiconductor, programmed with multi-function code that opens up a huge range of options. There is a built-in battery charging circuit that enables you to measure and monitor battery levels. It has a standard UART receive/transmit profile and AT command set to have full control over your device. This chip also has a built-in USB port with USB-to-serial programming and debug capability so no need for an FTDI-like chip. The development board is especially designed for low power portable projects.
