A minimalist USB host shield for the Teensy 4.0 development board

This repository contains the KiCAD 6 board files for the Teensy 4.0 minimalist USB host shield. The shield is designed to connect to the underside of the Teensy 4.0 board and provide a safe and stable USB-A host port in a small and lightweight size.

The Teensy board needs to be soldered to 0.1" male headers. It can then be mated to the shield with 0.1" female headers and pogo pins, or soldered directly using enamel wire to connect to the data pads on the underside of the board.
