Microduino USBHOST mainly supply the USB host function for some equipment, supports USB host controller and USB peripherals, such as mobile phones OTG function, keyboards, joystick, and camera.

==Features==

*Support MicroUSB interface；
*Small, cheap, stackable, opened platfrom;
*Open source hardware circuit design, compatible with the Arduino IDE development environment for programming;
*Define unified interface Microduino specification and contain rich peripheral modules. Set up the quick connection with other Microduino modules and sensors easily and flexibly.
*2.54 pitch row female connector for easy integration into breadboard.

==Specifications==

*Electrical specifications
**3.3V or 5V power;
**USB host uses power protocol of 5V/500mA;
**Using TC74HC4050 level conversion chip, provides the high anti-interference and stable output;
**D+, D- and VBCOMP has ESD protection function;
**The firmware/hardware control internal D+ pull up resistors (peripherals mode) and D+/D- pull down resistor (host mode);

*Communication
**Compatible with the MAX3420E USB peripheral which has the SPI interface;
**Comply with USB 2.0 specification (12 Mbps peripherals at full speed, full speed/low speed 12Mbps/1.5 Mbps host);
**Smart USB SIE；
**Automatic processing of USB flow control and double buffer;
**Process low level USB signaling.

*Supported devices：
**HID devices, such as keyboards, mouse, joystick and so on;

==Document==
Eagle PCB local download
Main components：
*Voltage converter chip：TC74HC4050 '''[[File:TC74HC4050AF.pdf]]'''
*Main control chip：MAX3421E '''[[File:MAX3421E.pdf]]'''

==Development==
*Need library： https://github.com/felis/USB_Host_Shield_2.0
*Serial debug is disabled under default condition.
**You need open the file "settings.h" from library folder;
**Find “#define ENABLE_UHS_DEBUGGING 1”, an then change to “#define ENABLE_UHS_DEBUGGING 1”, then save it.
*USB_Host_Shield_2.0 library usage：
**Bluetooth libraries：
An ordinary Bluetooth adapter. You can easily add different Bluetooth services, such as a PS3 or Wii controller or SPP which is supported through Bluetooth virtual serial port. A number of different examples can be found in the examples directory.
**HID library：
Connect USB peripherals. Such as a mouse, handle etc.
**BTHID library：
Connect HID devices via Bluetooth, currently supports HID mouse and keyboard.
**SPP library：
Allow you send data to your Microduino from PM/mobile phone via Bluetooth.
**PS4 Library：
Allow you to use the Sony PS4 controller via Bluetooth and USB.
**PS3 Library：
Use DUALSHOCK3, navigation or motion controller via Bluetooth and USB.
**Xbox Libraries：
**Xbox Libraries：
The library uses USB as the Xbox 360 controller.

==Application==
Light a LED via a mobile using the ADK example library：
===Prepare work===
*Prepared hardware：Microduino FT232R, Microduino Core, Microduino USBHOST, OTG cable, make sure your Android device supports and turn on the USB debug mode, USB cable；
*Prepared software：USB_Host_Shield_2.0 library, Arduino IDE(1.0 release and upper);
*Uncompress the zip folder and rename to “USB_Host_Shield” becasue Arduino IDE doesn't support any special characters, then copy to libraries folder of Arduino IDE；
*Connect the Microduino FT232R and PC using USB cable to download program and serial monitor；
*Connect a LED to I/O port D6 of Microduino-Core；
===Debug===
*Open the example program "ArduinoBlinkLED" from ADK folder of examples；
*Change LED_BUILTIN to Microduino pin in "#define LED LED_BUILTIN", such as "#define LED 6". But can't be D13, because D13 is used as SCK.
*After compiled, select the board "Microduino Core (Atmega328P@16M,5V)", download directly；
*Connect the mobile phone and Microduino USBHOST by OTG cable and USB cable;
*Open the serail monitor, will display "Arduino Blink LED Started";
*The phone will automatically pop up the application "ArduinoBlinkLED", download and install it；
*After installed the application, will prompte to open the USB connection fittings, and click OK to enter the program interface;
*Successful connection will show "connected", and can control the LED light on and off via the button.
