The MikroE USB I2C Click Board™ is a communication add-on board that acts as a highway intersection with one way in, three ways out for serial data. It incorporates a Microchip.
The USB I2C Click Board™ carries an MCP2221A USB-to-UART/I2C converter. The chip supports full-speed USB (12 Mb/s), I2C with up to 400 kHz clock rates and UART baud rates between 300 and 460800. The board communicates with the target MCU through mikroBUS UART (RX, TX) or I2C (SCL, SDA) interfaces. In addition to mikroBUS, the edges of the board are lined with additional GPIO and I2C pins. It can operate on 3.3V or 5V logic levels.
