The MCP212XEV-DB is a MCP212X is a developer's daughter board used to evaluate and demonstrate the MCP2122 or the MCP2120 IrDA standard encoder/decoder devices. A header allows the MCP212X daughter board to be jumpered easily into systems for development purposes. The MCP212X daughter board is designed to interface to several of the new low cost PICmicro demo boards. These include the PICDEM HPC explorer demo board, the PICDEM FS USB demo board, and the PICDEM LCD demo board. When the MCP212X daughter board is used in conjunction with the PICDEM HPC explorer demo board, the MCP212x can be connected to either of the PIC18F8772's two UARTs or the RX and TX signals can be crossed so the MCP212x device can communicate directly out the PICDEM HPC explorer demo board's UART (DB 9). This allows similar functionality to the obsoleted MCP2120 Developer's board (DM163008).
