Have a digital I/O intensive Arduino design? The DIO64-ARD is up to the challenge. Eight 8-Bit ports provide 64 digital I/O channels. All channels can be individually defined as either an input or output. Programmable Pull-Up resistors on inputs simplify connecting to “open-collector” sensors, switches, and contact-closures. Arduino I2C Wire routines control its operation. Also supports Third-Party libraries like those from Adafruit and SparkFun. |
