Description
The Adafruit Feather are a complete line of development boards from Adafruit that are both standalone and stackable. They're able to be powered by lipo batteries for on-the-go use or by their micro-USB plugs for stationary projects. Feathers are flexible, portable, and as light as their namesake.
This is the Adafruit Feather M0 Bluefruit LE - our take on an 'all-in-one' Arduino-compatible + Bluetooth Low Energy with built in USB and battery charging. At the Feather M0's heart is an ATSAMD21G18 ARM Cortex M0 processor, clocked at 48 MHz and at 3.3V logic. This chip has a whopping 256K of FLASH (8x more than the Atmega328 or 32u4) and 32K of RAM (16x as much)! This chip comes with built in USB so it has USB-to-Serial program & debug capability built in with no need for an FTDI-like chip.
- ATSAMD21G18 @ 48 MHz with 3.3 V logic/power
- No EEPROM
- 3.3 V regulator with 500 mA peak current output
- USB native support, comes with USB bootloader and serial port debugging
- 20x GPIO
- Hardware Serial, hardware I2C, hardware SPI support
- 8x PWM pins
- 10x analog inputs
- 1x analog output
- Built in 100 mA lipoly charger with charging status indicator LED
- red LED for general purpose blinking
- 4 mounting holes
- Reset button
The Feather M0 Bluefruit LE uses the extra space left over to add our excellent Bluefruit BTLE module + two status indicator LEDs.
The Power of Bluefruit LE
The Bluefruit LE module is an nRF51822 chipset from Nordic, programmed with multi-function code that can do quite a lot! For most people, they'll be very happy to use the standard Nordic UART RX/TX connection profile. In this profile, the Bluefruit acts as a data pipe, that can 'transparently' transmit back and forth from your iOS or Android device. You can use our iOS App or Android App, or write your own to communicate with the UART service.
The board is capable of much more than just sending strings over the air! Thanks to an easy to learn AT command set, you have full control over how the device behaves, including the ability to define and manipulate your own GATT Services and Characteristics, or change the way that the device advertises itself for other Bluetooth Low Energy devices to see. You can also use the AT commands to query the die temperature, check the battery voltage, and more, check the connection RSSI or MAC address, and tons more. Really, way too long to list here!
Use the Bluefruit App to get your project started
Using our Bluefruit iOS App or Android App, you can quickly get your project prototyped by using your iOS or Android phone/tablet as a controller. We have a color picker, quaternion/accelerometer/gyro/magnetometer or location (GPS), and an 8-button control game pad. This data can be read over BLE and piped into the ATSAMD21G18 chip for processing &...
