What is it?

Most microcontrollers support the SWD protocol as a convenient method to program and debug the chip. If you are making a custom PCB for a product or project, it's a good idea to add an SWD programming header to the board. PogoProg Model C is designed for use with such a 4-pin 1.27 mm header that uses the SWDIO, SWDCLK, VDD and GND pins. (Of course, you can use this programmer for any 4 signal lines, as long as the pitch is compatible.)

Why did you make it?

We design a lot of custom hardware and it's a common practice to add an SWD header to a PCB. We've been making do with make-shift programmers for a while now. We finally decided that it would be a good idea to make a well-designed product that would be helpful to the maker community at large.

What makes it special?

We've taken care to design PogoPin with ergonomics and aesthetics in mind. Pogo pins are expensive and inconvenient to source in small quantities, so we believe that providing a pre-soldered inexpensive programmer could be beneficial.

PogoProg is Open Source Hardware, and you can find the design files in the link below.
