If they’re both being fed from a beefier source, this is probably fine.

If you really want to pull power from the same source as the Nano, you could solder a wire directly to the large pin of the 5V regulator to bypass the whole thing. ST Micro NUCLEO-F446RE board support added to USB Host Shield 2.0 library USB Host Library 3.0-Alpha is out A library to interface Arduino with XKeys USB keyboards Running USB Host code on Digilent chipKIT board Using Data Monitor and Control Interface with PIC16 MCU CH Google Plus community has been created Bitmine A1 reference board. This is probably so that the USB bus can’t overwhelm the tiny voltage regulator on the Nano. It expects a feed of 7-12V off the green terminal block, or the VIN pin if you close that jumper. Worth considering that a host shield on an Arduino is generally a bad idea to begin with if you want to host a USB peripheral, use a processor that can do so natively - it will be both cheaper and less roundabout.

I could probably also patch USBCore.h to change the SS pin.Īnother caveat to remember: the USBHOST-4NANO won’t draw power from the Nano off the 5V pin. So, this is still a mystery, but at least the thing works now, if I jumper the correct pins. But that also appears to place SS on pin 10. I thought perhaps that this was a discrepancy between the USB Host Shield library 1.0 and 2.0, since the USBHOST-4NANO has been around since 2011. Once that is completed, File->Examples->USBHost20Libs will contain all the code we need to communicate with the USB Host Shield, the Bluetooth dongle, and the DualShock 4 controller. But why was the USBHOST-4NANO built to expect it on pin 8? To link the libraries in the Arduino IDE, go to Sketch->Import Libraries and navigate the file window to find that folder. The USB Host Shield library specifies that SS should be on pin 10, so that explains why that’s where the signal is. Why? To be honest, I haven’t figured that out. You could use this shield with Arduino Boards that have the same form factor as the Arduino Uno, like Arduino Uno Wifi, Arduino Mega, Arduino Due, and other Arduino clones as well. This shield supports USB 2.0 full/low-speed operation. But the USBHOST-4NANO is expecting SS on pin D8, and the Nano is using pin D10. This shield lets you communicate with other USB devices such as a barcode scanner and a keyboard. Turns out, the pins for SCK, MOSI, and MISO were correct. Eventually I got out my oscilloscope and using the troubleshooting instructions, I mapped out the pins. Well, I spent several days agonizing over this. You’re supposed to just plug the Nano into the shield, and be on your way:īut if you do this, and then fire up the USB host shield testing sketch… it doesn’t work. Support for more devices is currently in development.This is an Arduino Nano (or, to be completely honest, a cheap knockoff of one.) Please excuse the crappy soldering:īased on the naming (and product literature), you’d really think these would work together.I see that I didnt have it in my library (closest thing was Keyboard) so I went to the library.

USB to serial converters - FTDI, PL-2303, ACM, as well as certain cell phones and GPS receivers.HID devices, such as keyboards, mice, joysticks, etc.The following device classes are currently supported by the shield: This shield is shipped as the picture has shown, containing a populated and tested board plus a set of stackable headers, which is properly soldered.Īrduino Compatible board with standard connector layout, including ICSP connector, should work. Note: You will need to solder some of the pads to provide power to the USB socket and also the shield.

No more SPI re-wiring and code modifications! This is a great shield if you want to interface with Android phones or tablets too :) Thanks to the new interface layout it is now compatible with more Arduinos - not only UNO and Duemilanove but also big Mega and Mega 2560 work with Standard variant of this shield out of the box.
