These headers are made to work with the Teensy 4.0, Teensy 3.2, and Teensy LC development boards. Each kit of headers makes your Teensy breadboard compatible and will allow for stacking a Teensy and Teensy-compatible shield board. This kit includes five headers（two 13-pin, one 7-pin, one 3-pin, and one 2x7 right-angle SMT）, enough to connect your chosen Teensy in any configuration you need！
Note：This Header Kit can also be used for the Teensy 3.0 and 3.1, as the pin layout has not changed between the three versions.
