This FeatherWing will make it real easy to add datalogging to any of our existing Feathers. You
get both an I2C real time clock (PCF8523) with 32KHz crystal and battery backup, and a
microSD socket that connects to the SPI port pins (+ extra pin for CS). Tested and works great
with all of our Feathers.
Does not come with a micro SD card. A CR1220 coin cell is required to use the RTC battery-
backup capabilities! We don't include one by default, to make shipping easier for those
abroad, but we do stock them so pick one up or use any CR1220 you have handy. If you're not
using the RTC part of the FeatherWing, a battery is not required.If you need a precision RTC,
check out our DS3231 FeatherWing
For pinouts, wiring and code example that will run on all Feathers, check out the tutorial guide
which we keep updated as new Feathers come out. It has more information including diagrams,
example code for both Arduino and CircuitPython, pinouts, and more!

As of June 6, 2017 we now ship a version with a slightly different power supply setup that
reduces RTC brownouts. It is otherwise code and hardware compatible
