slick little board well supported with drivers from the community

great little board (very thin) that the community has adopted and for which cases are available for 3d printing on thingiverse.com. I would give it 5 stars, but I have to stick to 4 because of some design annoyances for a battery operated device. Just to name two, there's a led that cannot be turned off via software/gpio (it will drain a bit of your battery every minute of the way), and the voltage divider that's used to measure the battery level is hooked between the battery supply and ground with 2x 100K resistors. that may not be much, but it's still 0.02mA or so that cannot be trimmed during deep sleep. Other than that, it's tight and does what it's supposed to do really well for a reasonable price.
