Adafruit Adalogger FeatherWing – RTC + SD

Adafruit Item: 2922

This is the Adafruit Adalogger FeatherWing it adds both a battery-backed Real Time Clock and microSD card storage to any Feather main board. This FeatherWing will make it real easy to add datalogging. 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. Does not come with a microSD card. A CR1220 coin cell is required to use the RTC battery-backup capabilities.
