While you can now buy a RaspberryPi Zero or ZeroW with Header pins pre-soldered, there are still many boards available without them.
Those headerless boards need not gather dust, as you can quickly add headers to them. Even if your solder skills are a bad as mine.
In this video, I show you how Hammer Header Pins work and how fit them to your RaspberryPi ZeroW.
You can buy the Hammer Header kit here, if you’ve already got a RaspberryPi Zero without header that you need to get busy with.
Alternatively, checkout the pre-soldered RaspberryPi ZeroW option when you buy your own here.
