Product information:
If you are ready to start programming with your Arduino, previous Arduino typically had 8-bit/16MHz microcontrollers, but the development board of Feather M0 is a great breakthrough. Feather M0 is a minimal system with ATMEL atsamd21g18, 32-bit ARM Cortex-M0+processor, 256KB FLASH, 32kb SRAM, and a running speed of up to 48MHz. This small development board provides an Arduino hardware option, which is Arduino Zero. Solved the iterative issues that previously plagued the Arduino family, such as low storage limitations and dynamic memory stack overflow. Yes, this Feather M0 fully supports Arduino IDE and Arduino Zero library!
This Feather M0 is equipped with a programming power USB interface, surrounded by an RTC crystal oscillator, and a 600mA 3.3V regulator. Sufficient additional GPIO pins. Programming can be done through micro USB.
The unique feature of Feather M0 is a set of six configurable serial interfaces that can be transformed into a UART, I2C master, I2C slave, SPI master, or SPI slave. Some ports can be reused, with tasks assigned to each pin.
Provide complete sample code and explanations for the online Feather M0, including troubleshooting techniques, and support for Arduino Zero.
