The Digital I/O Wildcard™ adds 20 more digital inputs and outputs to your embedded controller.
This tiny 2" by 2.5" board is a member of the Wildcard series of mezzanine boards that connect to Mosaic embedded computers and instrument controllers.
Ideal for pulse width modulation (pwm) control, the Digital I/O Wildcard adds plenty of programmable digital I/O to your embedded controller. In addition to 4 dedicated digital inputs, you can configure up to 16 more channels for either input or output. Each I/O 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, initialize, read from, and write to the lines.
Output sink capability is sufficient to directly drive LEDs, electromagnetic actuators, and other low power devices.
