The 0.2 version MicroBoost boards came, and although they now fit properly in the Altoids gum case look-alike from Adafruit, the diode and MOSFET get super, super hot when charging an iPad. It still works just fine charging at 500 mA, but it looks like it's just not going to be able to do an amp.
I could use an B330LA-E3/61T and a SI3442CDV-T1-GE3 without changing the board. That MOSFET is the compliment to the part I use in Pi Power, and that's a buck converter capable of 2A of output power, so that gives me a good vibe. But I'm just not sure I'm all that interested.
