The SparkFun USB-C Host Shield contains all of the digital logic and analogue circuitry necessary to implement a USB peripheral/host controller with your Arduino. This means you could use your Arduino to interface with and control any USB 2.0 compatible device – thumb drives, digital cameras, BT dongles, and much more!

This version updates the USB Type-A connector to a USB-C connector and provides users with the option to power the shield from the5VorVINpins. The USB-C female connector also supplies 5V as any normal USB(downward facing)port would.

A four-wire serial interface is used to communicate with the host controller chip, so the shield connects the Arduino’s hardware SPI pins (D10-13) to the MAX3421E. All SPI signals are sent through a hex converter to step them down to 3.3V.
