There have been a number of really great suggestions for the À La Carte (ALC) on this forum.
I'm really interested to know: are there are any future plans to allow users to control power to specific blocks of ALC designs? For example, u-blox GNSS receivers and microSD cards are power-hungry beasts that require external circuitry to be powered-off.
Also, powering ALC designs appears to be currently limited to either USB or LiPo. I believe I saw a suggestion to add step-down voltage regulator blocks, which I agree would be a super idea. This would benefit users by allowing them to use power sources that exceed the 6 V voltage range of the AP2112 regulator (e.g. 12 V lead-acid).
