Just wanted to shout out to the awesome folks at Adafruit. I bought a few Mintyboost kits, one for me and
one to go through with a friend to teach him soldering. Well I put mine together and sure enough it wasn’t working.
I went back and bridged D- and D+ (I have an iPhone4) and I kept getting the “Not compatible” message. I rechecked
everything and even pulled out the camera and took photos, thinking I would have to post for help. Well after reading
ALL of the “read before posting” I finally double checked the new batteries. They were only putting out 1.3 V. Swapped
fresh batteries and it totally works now. I haven’t rechecked the voltages now that it’s working but I was getting 3.1 V out of
D-D+ and 5V. I should be 2V correct? Anyway, thanks for what is possibly the best customer service in any industry.
