I was curious as to how the “Raspberry Pi Prototying Pins” shown in the “GoPiGo Top Side” image at http://www.dexterindustries.com/forum/?forum=gopigo can be used - haven’t been able to find any documentation on this. Being one to fiddle, I actually soldered some headers onto these pins and can see that at least some of them appear to work - for example I was able to hook up some sensors to these pins and get some of them to work (directly from the Pi but connected to the broken out pins on the GoPiGo).
I was mainly just curious as to if there were any limitations around which broken out pins can or can’t be used. It seems like some of of my sensors on broken out pins work, and others don’t (sorry I don’t have which ones offhand), but I can’t tell if that is because of GoPiGo limitations around those pins, or if it’s a problem with my soldering or something like that.
Another specific question I had was around the I2C pins. I bought an I2C gyroscope that I have been trying to connect to the broken out I2C Raspberry Pi pins, but haven’t had any luck getting it to work. Should this be possible? Or can I only use the I2C pins with the grove connection on the GoPiGo itself?
I really have enjoyed tinkering with the GoPiGo - thanks for any help you can offer!
