Adafruit Adalogger FeatherWing - RTC + SD Add-on For All Feather Boards

A Feather board gains remarkable capabilities with the integration of the Adalogger FeatherWing. This accessory provides a battery-backed Real Time Clock and microSD card storage, enriching the functionality of any Feather main board.

Key features include an I2C real time clock (PCF8523) with a 32KHz crystal for time accuracy and a microSD socket that interfaces via SPI for data storage. The FeatherWing connects effortlessly using Feather Stacking or Female Headers, enabling seamless stacking and expansion.

Ideal for datalogging applications, the board enhances projects by offering reliable timekeeping and additional memory for data capture. Note that a CR1220 coin cell is needed to enable the RTC battery backup, but it's not mandatory if the RTC isn’t used, simplifying international shipping.

Comprehensive support is available through an updated tutorial guide that includes pinouts, wiring diagrams, and sample code for Arduino and CircuitPython, ensuring easy setup and compatibility across various Feather systems.
