Digital I/O Wildcard

This tiny 2" by 2.5" card is a member of the Wildcard series of mezzanine boards that connect to Mosaic's line of microcontroller-based embedded computers and instrument controllers.

Ideal for pulse width modulation (pwm) control, the Digital I/O Wildcard™ adds plenty of programmable digital I/O (input/output) to your instrumentation application. In addition to 4 dedicated digital inputs, you can configure up to 16 more channels for either input or output. Each IO line is also easily configured for pull-up, pull-down, or tri-state operation. This allows you to set the appropriate level of each I-O line in the interval between power-up and software initialization.

Pre-coded software drivers allow you to configure the I/O lines as either inputs or outputs in groups of four, and initialize, read from, and write to the I/O lines.

Output sink capability is sufficient to directly drive LEDs, electromagnetic actuators, and other low power devices.

• You can find price and delivery information on Mosaic's website, or contact us directly.
• You will also need a Compatible Controller Board to host this Wildcard.
