feather-sdio

A simple SDIO breakout FeatherWing adapter board.

This is a small adapter board that breaks out the SDIO bus on an Adafruit Feather so you can test SDIO peripherals (SD cards, SDIO Wi-Fi modules, etc.) without pulling out a breadboard every time.

Why

Prototyping SDIO on a Feather usually means wiring up the same handful of signals on a breadboard over and over. This board makes that a plug-in FeatherWing so testing SDIO is quick and repeatable.
