• The SparkFun USB-C Host Shield has similar features to our previous USB Host Shield (v2), but we upgraded the USB Type-A connector to a USB-C connector. Additionally, the board provides users with the option to select either the 5V or VIN pin to power the shield and USB port.

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

  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. While the logic-level for the shield is 3.3V, all the SPI signals are sent through a hex converter to keep the shield compatible with any 5V Arduino boards.

Required Materials

To get started with the USB-C Host Shield, users will need a few additional items. Users may already have some of these items, feel free to modify your cart accordingly. For users just getting started with electronics, we have linked a few tutorials to establish a foundation of knowledge to follow along with this hookup guide.

• Computer with an operating system (OS) that is compatible with all the software installation requirements.

• A compatible microcontroller/Arduino board; we recommend the SparkFun RedBoard Plus.

  !!! warning The recommended Arduino library for the USB Host Shield is not compatible with all microcontrollers or boards. For a complete list of compatible microcontrollers and boards, please refer to the README.md file of USB Host Library Rev. 2.0.

• USB 3.1 Cable A to C - 3 Foot - Used to interface with the RedBoard Plus (1) { .annotate }

  1. If your computer doesn't have a USB-A slot or your microcontroller/Arduino board has a different USB connector, then choose an appropriate cable or adapter.
