A.1.2 Headers

The Jackrabbit has 0.1" IDC headers at J1 (1 × 3) and J2 (2 × 2) for the power supply and an external battery connection. There are 2 mm IDC headers at J3 (2 × 5 programming port) and at J4 and J5 (2 × 20 Rabbit subsystems) for physical connection to other boards or ribbon cables.

Figure A-3shows the Jackrabbit footprint to help you lay out the “motherboard” into which the Jackrabbit is plugged in. These values are relative to the mounting hole closest to header J3.
