In your schematic editor, click the Add Part button and search for "Pro Micro" to find the component. 3. Verify the Footprint arduino pro micro eagle library
If you prefer not to create your own:
The physical layout of the pads on the PCB. This ensures that when you order your board, the holes for the Pro Micro headers are spaced exactly mm) apart. | Pin | Signal | Arduino Pin |
