DFRobot Gravity GPIO Expansion Shield for Arduino 25c provide high-quality jumper breadboard cablesBuild Faster with the GPIO Expansion Shield for Arduino Gravity An Arduino UNO has a limited number of GPIO pins but what if it is not enough? The GPIO expansion shield specifically designed for Arduino UNO type boards. This shield greatly expands the GPIO resources to 36 pins in total, including 14 digital pins, 6 analog pins and 16 I2C pins. In addition digital and analog pins include the DFRobot "Gravity" interface, giving you in line power and
