DESCRIPTION
The DIO64-ARD adds 64 digital I/O channels to an Arduino/Genuino UNO, MEGA 2560, Due, or other compatibles. Four industry standard MCP23017 chips are used to create eight 8-bit ports via the I2C bus.
Channels are individually defined through software to operate as either an input or output. Optional Pull-Ups can be enabled for channels configured as inputs.
The DIO64-ARD occupies four consecutive I2C addresses. Standard Arduino Wire library functions control its operation. In addition, the DIO64-ARD fully supports popular third-party software libraries like those available from Adafruit and SparkFun.
External devices connect to the DIO64-ARD through a 40 conductor IDC ribbon cable style connector and two 20 position headers. These connectors also provide access to the system operating voltage and ground.
