ADK USB Host Shield for Arduino – Add USB Device Support
ADK USB Host Shield – Add USB Host Capability to Arduino
The ADK USB Host Shield allows your Arduino board to function as a USB host, enabling direct connection of USB devices like keyboards, mice, and game controllers. Based on the MAX3421E chip, it handles the USB protocol and communicates with the Arduino via SPI. Ideal for HID and Android ADK projects.

What You Can Build With This
- USB keyboard input for data logging or interactive installations.
- Connect a game controller to pilot a robot or play retro games.
- Use a USB flash drive for file storage with the USB mass storage library.
- Create Android Open Accessory projects to interface with smartphones and tablets.
Compatibility
This shield is designed for Arduino Uno R3, Mega 2560, and Due. It uses the standard SPI pins, but on Leonardo or Micro, the SPI pins are located on the ICSP header rather than D11-D13, so wiring adjustments are needed. The MAX3421E operates at 3.3V with an onboard regulator, making it safe for 3.3V boards. It works with a wide range of low-speed and full-speed USB devices.
Wiring Notes
Stack the shield directly onto the Arduino headers. For the Due, nothing extra is needed as it's 3.3V tolerant. When using a USB hub, consider external power if the total current draw exceeds 500mA. Install the USB Host Shield Library for Arduino to get started quickly.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino Uno?
Yes, it is plug-and-play with the Uno R3. Just stack it on and use the USB Host Shield Library.
Can I connect multiple USB devices at once?
Yes, by using a USB hub. However, ensure the hub is powered if the devices draw more than 100mA total.
Does it work with USB 3.0 flash drives?
USB 3.0 devices are backward compatible in most cases, but they may require more power. A powered hub is recommended.
