Overview
The MCP23X17 16-bit GPIO Expander 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.
- Demonstrates the MCP23X17 devices in a simple I/O application
- ICSP header for the PICmicro allows users to customize firmware to further evaluate the MCP23X17
- Jumpers and headers allow the MCP23X17 to connect directly to custom applications for prototype work
- Can be powered from a 3.0V to 5V DC power source (connected to the +5V and GND test points)
