A Feather board without ambition is a Feather board without FeatherWings! This is the Adalogger FeatherWing: it adds both a battery-backed Real Time Clock and micro SD card storage to any Feather main board. Using our or you can connect a FeatherWing on top of your Feather board and let the board take flight!
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, . If you're not using the RTC part of the FeatherWing, a battery is not required.
For pinouts, wiring and code example that will run on all Feathers,

Revision History:
- As of June 22, 2022 - we have changed the crystal in the Adalogger to a smaller package and may ship either a SOIC or HVSON version of the same RTC chip. Functionality and pinout are identical!
- 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
