GPIO Hammer Header (Solderless)

by Pimoroni

Absolutely no soldering required! All that's needed is a few gentle taps with a hammer and bazinga! Your header is securely attached to your Pi Zero or pHAT.

If your soldering isn't quite up to scratch, or you just don't own a soldering iron yet, then these nifty hammer headers might be just the job. They come in male and female flavours, and use crafty little retaining nubbins to grip tightly into the holes on the PCB.

The installation jig kit contains two acrylic base pieces, onto which your Pi Zero or pHAT sits, two steel bolts, two nuts (use these on top of the PCB to hold it tightly to the base of the jig), an acrylic top piece onto which you hammer, and both a male and female header. Make sure you carefully read our guide for fitting hammer headers, and use a sturdy, stable, well-supported surface while hammering.

We strongly recommend using our installation jig! If you want to try without it then godspeed to you but it is a delicate and tricky process! The female headers are simpler to insert than the male headers as you can hammer straight onto the plastic of the header, but the male ones are particularly tricky without the jig.

Please note: we can't be held responsible for any damage that you may cause to your Pi Zero, pHAT, fingers, or headers while fitting them. If you follow our guide carefully then you should be fine. If this worries you, then get yourself a soldering iron instead!

Price is a bit steep for a few bits of plastic, but its also not crazy expensive. Managed to do 2 of the male headers. To use it work along the top bracket and hit it medium hard repeatedly, dont just wallop it with a single hit and expect it to be in. Not sure how long this thing will last though ?

Gentle taps with the hammer are not sufficient. Read the instructions carefully several times before banging anything. Gradually increasing the strength of taps to the point at which the pins bent prior to being in the correct position. Managed perhaps 2/3 of the way there on all of the pins prior to the bending. Will go and find someone that is able to solder a head on.....

Great Product! Works very well. The only thing that you have to be cautious of is that all the pins are hammered in evenly. Installation was a breeze, and the installation jig helped a lot.
