Note that this part can be tricky to solder straight. The easiest way is to get 1 pin soldered, even if its' crocked.

After this, the header should be lined up.

Next, se need to solder the USB Serial adapter onto the header pins. This board converts the serial protocol that the processor speaks to usb.
This converter chip is a fine pitch surface mount part, so we have it on a premade board. With practice, it is possible to solder parts this small though!
Just like soldering the header, solder 1 pin in place, align the module, and then solder the rest of the pins.
Make sure the board isn't at an angle, because we need to leave room for the USB cable to plug in.
