I’m confused by the description for the SparkFun Buck Regulator Breakout - 3.3V (AP3429A). The intro paragraph says that it can handle an “input voltage range of 2.7V to 5.5V”, but the Product Overview says that the input can range “from a 3.9 to 5.5V input voltage range”. Which is it? I’d like to use a traditional 3.7V LiPo battery with this item.
It looks like a typo for the 3.3v version, it should say “3.9 to 5.5v” Hardware Overview - Hookup Guide - AP3429A Buck Regulators - Thanks for pointing this out, we’ll get the description fixed ASAP!
