Adafruit Feather Main Boards
- Adafruit 2796, The Adafruit Feather 32u 4 Adalogger Datalogger can form the core for your next data logging project with its built in SD card slot. The Atmel ATSAMD21G18 is a very interesting chip, it's the one chosen to power the Arduino Zero so you know it will be supported by Arduino development tools, libraries & IDEs. It has a Cortex M0 core with 256kbytes of Flash memory, 32 Kbytes of RAM, & runs at 48 M Hz & 3.3V DC. Compared to the Atmel 32U4 it has 8 x the Flash memory, 16 x RAM & a much faster clock speed, 48 Mhz compared to 8 M Hz. New to Feather? Adafruit have designed a range of processor boards with a consistent board shape & pinout together with a range of add-on boards with a huge range of functionality. The main boards are based on several popular 3.3V DC microcontrollers (MCU) so that you can choose the one that suits your requirements or your budget. MCUs include the 32U4, Atmel ATSAMD21G18 with an ARM Cortex A0 core, & the popular ESP8266 which is widely used in Internet of Things (Io T) projects. Because Adafruit has used the smallest components available there's room at one end of the board for a specialist function such as an SD-card holder, Bluetooth LE, packet radio, Lo Ra, a prototyping area or even Wi Fi. The Feather main boards feature a USB (Universal Serial Bus) port for power & programming, a Li Po battery connector, 20 x GPIO pins including PWM output on all pins, 6 x analogue inputs, 1 x analogue output, & support for serial, I2C & SPI in hardware. Each one has a 3.3V DC regulator which is able to supply up to 500m A peak current. The boards have a 100m A Li Po charging function with a status indicator LED & there's also a general purpose LED for blinking. The Feather boards are about &8531; x the size of an Arduino UNO & there's even a Reset button. Once you've chosen your processor, select one or more Feather Wing add-on boards & get developing. The range
Includes:: development tools such as prototype boards & an over-size board with screw terminal blocks for external wiring. Supplied with an assembled & tested main board plus strips of 01.in. header pins for you to solder on as required. Adafruit supply an extensive free tutorial which contains everything you could need.
