When designing printed circuit boards (PCB’s), panelization is a common technique to manufacture multiple boards simultaneously. A widely used method for separating these boards after production is the use of breakaway tabs, often referred to as mouse bites. The mouse-bite.pretty library offers a convenient collection of KiCad footprints that simplify this process. What Are Mouse Bites? Mouse bites are
