Pins (header), 24 pins, 0.1 inch (2.54 mm) spacing

This 24x1 size is normally used with Teensy 3.5 or Teensy 3.6 or Teensy 4.1. Two of them are required, one for each side of the board.

Header Pins must be soldered to make reliable electrical contact.

Placing the circuit board loosly onto these pins does not work.
