Gravity: PCA9555 IIC to GPIO Board V2.0

SKU: DFR0013

The PCA9555 IIC to GPIO Board is designed to address the common issue of inadequate digital I/O when using Arduino in applications such as robotics or interactive media. By using the IIC to GPIO shield, users can expand their Arduino setup with 16 digital IO ports, facilitating more complex and versatile projects. The board operates with a module power supply of +5V and features internal pull-up for its 16 digital I/O ports. Users can configure up to eight modules simultaneously with unique addresses ranging from 0x20 to 0x27, allowing for parallel operation on the IIC bus. The module's compact size (56x53mm) makes it ideal for integrating into various projects where space is a consideration. With this shield, Arduino users can overcome limitations and explore more possibilities in their creative and technical endeavors.
