These breadboard compatible 0.100″ breakaway headers are typically what you would find with all of our breakout boards. Breakaway Headers are a great way to connect small perf-boards or breakout boards to a breadboard or other 0.100″ pitch board. The headers are made up of two rows of 40 pins with a 90 degree bend. They can easy be snapped apart to any length required and work well when a vertical header is not desired.
