MCP43XX Evaluation Board
MCP43XX Evaluation Board ( MCP43XXEV )

The MCP43XX Evaluation Board allows the system designer to quickly evaluate the operation of Microchip Technology’s MCP4361 Digital Potentiometer device. The board uses the TSSOP20EV Generic PCB and has been populated for the MCP4361. The 6-pin header (PICkit Serial) has been jumpered to the MCP4361’s appropriate pins. This allows the PICkit Serial to communicate with the device....
