Hey Kevin,

The two middle offset pins are a feature that should friction-fit the 6-pin header to make soldering easier. It may look a bit weird, but it works great!

Adding additional holes to stabilize the board sounds like an interesting idea, let me know how it works if you end up trying it!

Also, I currently use an updated version of this design with only 4 pins for SWD-capable microcontrollers. It’s essentially the same thing but scaled down to 4 pins and without any keying pins.

I used gerbview under Linux to look at the gerbers in the PogoProg-RTM1.zip file. It shows the middle two pins of the 6-pin header as being offset from the other 4 pins.

The other thought I had is whether it would be better to include two other holes in the corners on the side opposite the row of pogo pins to use some header pins as a way to help stabilize the two boards in relation to each other? It would minimize the chance that the pogo pins would get damaged if the open edges of the two PCB’s ever got squeezed together.

For SWD you can get away with VSS/DIO/CLK, but some programmers want to sense the target voltage so you might want to use Vdd as well. I haven’t had a need for reset and the boundary scan SWO pin, but they are needed for some use cases.

I want to build one for JTAG/SWD used in most of Cortex-M micros.

I am still struggling there is not a standard pinout for reduced connectors.

Min: VSS/DIO/CLK/
Max: VSS/VDD/DIO/CLK/RST

Segger defined a standard pinout as “niddle kit”, which use 5×2 pinout.

It was super nice of you to change the name so quickly. A++ WOULD BERATE AGAIN 😉

PS, the comments about naming seem a little harsh. Granted someone else is already using the pogoplug name, but given a programmer based around pogo-pins, it’s not as the though that name is worthy of an award for originality.

wow, that’s really disappointing. I second this – I’ve seen “Pogoprog” before and I was surprised that this website isn’t actually it. It was the ubertooth page I was thinking of.

PLEASE use a unique, new name. If you “accidentally” use the identical name as someone else, at LEAST make sure you’re not naming and selling a nearly identical product.

Stay tuned! Next week we will demonstrate our new Interchangeable Bootloading Module, which will will call “IBM” 😉

Sorry about that! This was an internal project we were testing on one of our boards, and I just stuck with the random name we came up with. I added a note to clarify at the beginning of the post with a link to your site.

Edit: Just did a little find/replace on this page. The images don’t match the text, but that shouldn’t cause too much trouble 😀
