The MCP23X17 Evaluation Board demonstrates simple input/output functionality of the MCP23017 (I²C interface) and the MCP23S17 (SPI interface). The system demonstrates the simplicity of monitoring four pins configured as inputs and applying a predetermined pattern on LEDs connected to the remaining 12 pins configured as outputs.
ICSP™ header for the on-board PIC16F818 microcontroller allows users to customize firmware Jumpers and headers allow the MCP23X17 to connect directly to custom applications for prototype work Can be powered from a +3V to +5Vdc power source (connected to the +5V and GND test points)
