The I2CDIO8 device provides an 8-bit general purpose, parallel I/O expansion for the I2C bus.
This device contains 3 address pins and multiple configuration registers for input, output, and polarity selections.
The system master has the ability to enable the GPIO port as either inputs or outputs by programming the configuration bits.
Up to 8 MCP23008 chips may be chained to each I2C port using 3 on-board address jumpers.
Do not exceed 5VDC on any input. May be powered by the I2C bus or powered externally (jumper-selectable).
This is a general purpose I²C device compatible with all computing platforms and IoT technologies, including Raspberry Pi, BeagleBone, Arduino, Particle, BridgeX5, and many more. All ControlEverything.com devices support a strict +5V I²C Bus standard.
