USB I2C click - Example

USB I2C click carries an MCP2221 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 115200. 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.
