This is a MCP23017-based hacker-friendly GPIO expander board. I've designed it because I routinely don't have enough IOs in my ESP8266 and Raspberry Pi creations, and I've used my prototyping experience so that the board is convenient for everybody!
MCP23017 expanders are very popular, and there's even a Linux driver for MCP23017! For Arduino code, you might want to use Adafruit's MCP23017 library. For Raspberry Pi, you can use the Linux driver (enabled by a single config.txt line) . If you're using other programming language or need any other instructions, let me know, I'll write some example code for you and add it here.
