IGLOO PLUS Starter Kit User’s Guide

I/O Test Pins

All IGLOO PLUS FPGA I/Os are available on headers located on the top and bottom of the device (

Figure 4-17

 and 

Figure 4-18

). These test pins are multiples of 100 mils apart, so developers can easily attach headers and place an 

extension card on top with an off-the-shelf breadboard for a low-cost solution for integration. In order to use I/Os 
assigned to the LEDs, DIP Switches, and push-button switches, the 2-pin jumper on their path must be removed first to 
disconnect the assignment.
