Adafruit Adalogger FeatherWing - RTC + SD Add-on for Feather Boards

The Adafruit Adalogger FeatherWing is an add-on board designed for all Feather main boards, providing a battery-backed Real Time Clock (RTC) and micro SD card storage capabilities.

This FeatherWing features an I2C real time clock (PCF8523) with a 32KHz crystal and battery backup, and a microSD socket that connects to the SPI port pins plus an extra pin for CS. It's tested and compatible with all Feather boards, making it easy to add datalogging functionality to your projects.

Important: Does not come with a micro SD card. A CR1220 coin cell battery is required to use the RTC battery-backup. The battery is not included by default for ease of shipping internationally but can be purchased separately.
