BeagleBone Black Debug Connector

The BeagleBone Black has a 6-pin debug connector, which gives you access to a serial console. However these pins are located right next to the P9 connector which makes it difficult to connect to while a cape is installed. So I created a 90-degree adapter. You can also purchase these at various places, but sometimes I just like the challenge of building things.

Connector

I had some connectors in my parts box, and thought they might work as is, but as you can see here, they stick up above the P9 connector by a bit, and I was concerned about touching the bottom of an installed cape. Bigger...

Straigten Pin

So I decided to remove the metal pins. The first step is to straigten the pin on the side with the beveled edges (where the header pin is inserted). Bigger...

Other Side

Here's a picture of the other side (for reference). Once the correct side is straigtened, you can push the pin out. Bigger...

Pin

This is the removed pin. I trimmed the bent portion off. Bigger...

Trimmed Pin

And here's the trimmed pin. Bigger...

Bend

Bend the remaining portion as shown. Bigger...

Hold Pins

I then mounted the pins on a piece of straight header so that they'd all be aligned properly. Bigger...

Right Angle Header

Then connect some right angle header. Bigger...

Solder

And solder. I just put the iron on the outside, and the solder on the side. I could have put some solder on the other side of the pin, but I didn't want to risk getting any solder on the inside of the pin. Bigger...

Add Heatshrink

This is optional, but I added some heatshrink to each pin. Bigger...

Shrunk

And this is the heatshrink shrunk to size. Bigger...

Installed

Here we see the FTDI cable plugged into the installed right angle header. Bigger...
