Arduino Compatible Sensor Expansion Shield
This shield makes connecting 3-pin analogue sensors a snap. Each of the 6 DuinoTECH analog inputs is broken out to individual 3-pin connectors. There is also a 4-pin communications port that can be set for either UART or I2C. Each of the digital pins is also given a 3-pin vertical header. Plug and Play connection for servos, sensors, switches and more!
