Description

A Feather card without ambition, it's a Feather without FeatherWing card! The Adalogger FeatherWing will add an RTC module with battery and support micro SD for storage on any card Feather. 

By using the stacking connectors for Feather or the female connectors for FeatherYou can easily connect this FeatherWing Feather card and take flight.

This FeatherWing Adalogger allows you to add the datalogger to any Feather card function. The RTC (PCF8523) circuit with a 32 kHz quartz will use the I2C connection and the microSD card will it use the SPI connection with an extra CS pin. This module is tested is functional on the Feather maps at base of ATmega32U4, ATSAMD21 and ESP8266.

We recommend to use the library by default SD from Arduino to use the microSD card. on the ESP8266, the CS pin will be on the GPIO15, on Atmel M0 or on the 32U4 it will be the 10 GPIO pin. It is possible to cut the track to affect another pin. To use the RTC module, use the RTC of Adafruit Bookstore.
