WiFi SD Adapter

Description

microSD to SD adapter with an ESP32-C3 "inbetween". It allows wireless access to the microSD card without removing the SD card from its slot. It does this with two bidirectional bus switches that disconnect the microSD card from the host and connect it to the ESP32 for the duration of the wireless access.

Includes a single-sided USB C connector for programming. Might only work on a USB A host port though because it's single-sided. The single-sided is necessary to not become too thick for a USB C connector.

Gerbers, iBOM, etc. can be found in the Exported folder.
