The MCP23017 device provides 16-bit, general purpose parallel I/O expansion for I2C bus.
If you are running low with your Arduino or Raspberry pins this board is for you! The board can increase I/O pins up to 128 - you can connect up to 8 boards to each i2c bus.
If you buy more than 4 pcs. I can provide 16 roller shutter (16 up and 16 down egnines) and 32 buttons (16 up and 16 down) program for Arduino Uno.
5V operating voltage
Operating Temp Range (°C) -40 to 125
Max. Bus Frequency (kBits/s) 1700
reverse polarity protection!
communication noise protection
dimmension: 40x40 [mm]
Boards selling without goldpins soldered. If you want me to solder it choose goldpin product option.
