SCIDYNE Corp. recently expanded its product line by developing a digital I/O interface for Arduino hardware. The DIO24-ARD makes it easy to connect to solid-state I/O racks, switches, relays, LEDs, and many other commonly used peripheral devices. Target applications include industrial control systems, robotics, IoT, security, and education.
The board provides 24 nonisolated I/O channels across three 8-bit ports. Each channel’s direction can be individually configured as either an Input or Output using standard SPI library functions. Outputs are capable of sinking 85 mA at 5 V. External devices attach by means of a 50 position ribbon-cable style header.
The DIO24-ARD features stack-through connectors with long-leads allowing systems to be built around multiple Arduino shields. It costs $38.
