演示板, USB至I2C/UART 主转换器桥

The from is a MCP2221 I2C demonstration board. The MCP2221 I2C demonstration board allows the user to communicate through a PC application to I2C slave devices by using the MCP2221 device as USB to I2C master converter bridge. The board can also work at the same time as a USB to RS232 UART bridge.
