The Seeeduino Cortex-M0+ features an Atmel SAMD21 MCU which is based on a 32-bit ARM® Cortex®-M0+ processor. With the help of this powerful core, SAMD21 is much more powerful than AVR and can achieve many functions and more complex calculations that cannot be implemented on AVR chips. The Seeeduino M0+ is a brand new product line that is fully compatible with Arduino Zero and we currently have Seeeduino Cortex-M0+ and Seeeduino Lotus Cortex-M0+ in this serial. The Seeeduino Cortex-M0+ has the same header pinout as the Seeeduino Lotus Cortex-M0+, including 14 digital I/O (10 PWM output) and 6 analog I/O. On the meantime, it provides 3 on-board Grove connector: two I2C and 1 UART. If you want to use more grove port, you can use a Base Shield V2 to work with this board. On top of that, Seeeduino Cortex-M0+ is the first Seeeduion development board with a USB type C interface. USB Type C is the future trend: the plugs are reversible, higher data transfer rate, and more scalable functions. We will introduce more development boards with Type C. You can use type C to supply power and transmit data or use the 7~15V DC jack to supply power for this board.
