DESCRIPTION
The DIO24 ARD adds 24 digital I/O channels to an Arduino/Genuino UNO, MEGA 2560, or other (+5 Volt) compatibles. The specialized circuitry makes it easy to connect Solid-State I/O Racks, Switches, Relays, LEDs, and many other commonly encountered peripheral devices.
External devices connect to the DIO24-ARD through a single 50 conductor IDC ribbon cable style connector. The pin-out is fully compatible with standard 8, 16 and 24 position Solid State I/O module racks available from a variety of third-party vendors.
Each DIO24-ARD channel is individually defined through software to operate as either an input or output. Channels configured as outputs are capable of sinking 85ma.
The DIO24-ARD appears as a Serial-Peripheral-Interface (SPI) device. Only one Arduino digital output is required to function as the dedicated board Enable leaving all remaining Arduino digital I/O available for other purposes.
Get things up and running quickly with the supplied library. It includes routines for bit manipulation, port read and write, and controlling data direction.
