• Jumper-selectable power supply: 3.3 or 5V (up to 500 mA)
• PICkit Serial Analyzer header – the board can be directly plugged into systems
that have this type of header. The MCP2221 Breakout Module provides
UART-to-USB and USB-to-I
2
C/SMBus access.
• DIP form factor (two 7-pin headers spaced at 600 millimeters)
By using the provided software and libraries, the user can create personalized PC
applications, using the breakout board as a USB-to-UART and/or USB-to-I
2
C/SMBus
protocol converter.
2.4 MCP2221 TYPICAL USAGE SCENARIOS
The MCP2221 can be used in systems where a UART bus is available. The MCP2221
enables the USB connection to a UART-based system.
