Overview

Product Overview

Turn an Arduino Pro Mini into the host for keyboards, mice, gamepads and Android devices with this compact USB host module powered by the MAX3421E chip. It connects over SPI and works with the USB Host Shield Library 2.0, letting your microcontroller read HID peripherals, accept input from PS3/PS4/Xbox/Wii controllers (wired or via dongle), and communicate two-way with phones using the Android Open Accessory model. The module also supports PTP for basic DSLR camera control, so you can trigger shutters or integrate cameras into projects. Designed for tight enclosures, its small SPI footprint stacks cleanly with Pro Mini boards and provides a practical way to add sophisticated user interfaces to robots, automation, and custom hardware. Android ADK ready

Questions & answers

Frequently asked questions

Yes. It is designed for Arduino Pro Mini projects and uses the MAX3421E USB host controller over SPI. With USB Host Shield Library 2.0, the Pro Mini can read supported USB peripherals and Android ADK devices.
This module is sold pre-soldered, reducing setup time for breadboards, jumpers, or compact stacked builds. You still need to wire the SPI connections and install the USB Host Shield Library 2.0.
It communicates with the microcontroller over SPI, using the standard SPI signals plus board-select or control wiring required by your setup. The MAX3421E handles USB host functions while the Arduino runs the application code.
Yes. With USB Host Shield Library 2.0, it can accept input from supported PS3, PS4, Xbox, and Wii controllers, either wired or through compatible dongles. That makes it useful for robot driving, menus, and custom controls.
First check SPI wiring, power and ground, library installation, and whether the device class is supported by USB Host Shield Library 2.0. Controllers may require the correct wired connection or dongle, and Android use requires Open Accessory support.
