Post 49: Another Problem with the mpja Breadboard T-connector
(see post 45)
So, since I'd gone to the trouble of identifying the pin-outs, I decided to use the connector. It's a wonder I didn't burn out my Raspberry Pi!
As you can see from the image above, the connections to the breadboard power rails are reversed from every one of the 4 breadboards I own (including the one that came with the T-connector). I (foolishly) assumed that the T plug would connect Ground to Blue and voltage to Red. Nope. It's backwards. So nothing I tried worked. I wasted a couple hours and luckily I didn't harm my Pi.
