The expansion board is designed for DFRduino M0 or Bluno M0 sets. The board has 31 GPIO pins (including 6 PWM and 6 ADC inputs), UART, I2C and SPI interfaces. The pins are color coded according to the Gravity standard. DFRobot DFR0412
The expansion board is designed for DFRduino M0 or Bluno M0 sets. The board has 31 GPIO pins (including 6 PWM and 6 ADC inputs), UART, I2C and SPI interfaces. The pins are color-coded according to the Gravity standard, which makes it much easier to identify inputs and connect sensors. The module is powered by a screw connection with a voltage ranging from 7 to 23 V. There is also a connector for powering servos. A user manual is available on the product wiki page.
