I have been looking for a way to use my Raspberry Pi
A as it is has no ethernet port. Most of my Pi work is done through ssh.
I was very impressed with the reviews of the DebugClip kickstarter
, in fact it sounded to good to be true.
As it was only £5.99 I took a punt.
Wow! Is this thing cool!
The Debug Clip comes as a kit that has to be soldered together but the guide http://wiki.ryanteck.uk/RTK-000-006_Soldering_Guide made that a breeze.
You can optionally power the Raspberry Pi
directly from USB connection, just set the jumper to closed. Here is the clip powering my Pi. Only that single USB wire is required!
You will notice that the clip appears to be 'floating' about the GPIO pins, the early Pis had larger pins and although I could squish it down it would be a pain to remove it again. This level of contact works fine.
The second best thing about the clip is that you do not need to install anything, on either the Pi or the host Linux
machine. I did not investigate connecting it to Windows or Mac machines but I can see plenty of people have.
The LEDs are a great addition and show when the serial modem is sending and receiving data.
To connect just find what serial device Linux
has assigned the clip and run.
screen /dev/ttyACM0 115200
Where /dev/ttyACM0 is specific to your setup. Although I did not use it Ryanteck have script that will find the device on most setups
