8-Pin I2C Click Board™

Product Code: MIKROE-4241

How Does The 8-Pin I2C Click Board™ Work? The 8-pin I2C Click Board™ is a breakout board that simplifies the connection of add-on boards to the mikroBUS™ socket. This Click board™ represents a small-size PCB that can be connected to the mikroBUS™ socket like any other Click board™, with a 2x4 female header placed on itself. Each of the header pins is corresponding to a pin on the mikroBUS™ socket being used such as I2C lines (SCL, SDA) with two jumpers for the I2C lines pull-up function selection, 3V3 power supply, and ground. This Click board™ allows easy pin access and manipulation while retaining a perfect connection quality at all times. Being compatible with Apple's MFI is the most important feature of the 8-pin I2C Click board™ which ensures its proper operation with additional Apple accessories. The name is a shortened version of the long-form Made for iPod, the original program that ultimately became MFI which refers to peripherals that work with Apple's iPod, iPad, and iPhone.

The 8-pin I2C Click Board™ communicates with MCU using the standard I2C 2-Wire interface. Lines of the mikroBUS™ to which this Click board™ is attached, are shared through the top 8-pin female header, which mirrors the pins of the connected mikroBUS™ socket. The 8-pin I2C Click also shares the 3V3 power rails, which makes it compatible with any other power compatible Click board™ and development systems. The 8 pin I2C click Board™ is designed to be operated only with a 3.3V logic voltage level. A proper logic voltage level conversion should be performed before the Click board™ is used with MCUs with different logic voltage levels. However, the Click board™ comes equipped with a library that contains easy to use functions and a usage example that may be used as a reference for the development. SPECIFICATIONS Type Adapter Applications Can be used for for expanding the connectivity of the development system with the mikroBUS™, and ideal for communication with numerous devices that share the identical slave address on the same bus. Compatible with MFI (Made For iPod) On-board modules 8-pin I2C Click is a compact add-on board that represents a breakout board that simplifies the connection of add-on boards with 8 pin Female Connector to mikroBUS™ socket. Key Features MFI compatibility, no regional restrictions, expanding connectivity, retaining a perfect connection quality at all times, and more.
