I bought a Teensy 3.2 board, and the package included some headers: Teensy & headers

I want to use the Teensy in a breadboard, and so I plugged in the headers and put the entire thing in my breadboard: Teensy in breadboard

The little holes in the Teensy and the header pins don't make a good connection, so I have to apply some sideways pressure to make it work. I guess the intention is that I solder those pins to the Teensy, right?

I don't have a soldering iron right now though and I would like to keep the Teensy in its current state, so is there another way to connect it to a breadboard? Thanks for the help!

  • \$\begingroup\$ dimensions get critical fitting square pegs in round holes, unless press fit type, solder ...or Swiss round contacts , which were not used here it seems \$\endgroup\$ – Sunnyskyguy EE75 Oct 8 '16 at 15:59

Get a set of press-fit headers (e.g. these) instead. The loops press against the sides of the holes in order to make a decent connection. Note that they may come loose when the board is removed from the breadboard though.

If you want to have reliable connection soldering is the way to go.

For a few connections and for toying around put a piece of wire through the hole and twist the ends using pliers. It could leave some marks on the PCB though.
