One handy trick to get around that problem is to keep some spare stacking headers around to use as spacers between shields. Ethernet shields are notorious for this because the RJ45 jack is so physically high: the stacking headers are shorter than the RJ45 jack, so if you put another shield on top it will probably not sit down flat and the jack may short out tracks on the top shield. Physical ClearanceĮven if your shields have stacking headers they may still have parts that are physically high and can foul another shield placed on top. You can see the stacking headers clearly on the top shield in the photo above. Try to use stacking headers on your shields whenever possible because it makes life much easier for you later if you need to stack them together. Many shields are fitted with regular male break-away headers that protrude down from the shield but don't provide a place on top where another shield can be plugged in. So how do you know if shields are compatible with each other? Stacking HeadersĪll shields except the top one will need stacking headers. Sometimes shields can be stacked together and sometimes they can't, and it's not always obvious if they'll work together or not. Most of the time you'll only have one shield at a time fitted to your Arduino, but some people really take it to an extreme! There is no specific number of "slots", and shields can be stacked on top of each other to combine their features. With Arduino shields it's not so clear-cut. The computer sees each card in isolation and they don't conflict with each other. It could be 6 video cards, or 1 video card and 5 network cards, or whatever. And because (with some exceptions) each card is totally independent, it doesn't matter what you use. The big difference, however, is that computer expansion slots are finite and independent: if your computer has 6 slots, you can put in 6 cards.

Please also remember to visit the 'USB' category of our blog where we have posted many different guides and tutorials on how to use our contributions to the library, including PS3 controller, PS4 controller, Xbox controller and Bluetooth enabled devices (SPP, PS3, Wii, etc.Just as desktop computers have "expansion slots" into which you can add expansion cards for video, sound, networking, and many other things, Arduino boards have "headers" on top where you can fit "shields" to add more functionality. Remember to visit the blog with updates to the library, including new features and device classes: In the dropdown list below you can decide to get the board shipped with pre-cut matching headers. This shield is shipped without headers by deafult.

This shield only work with Arduino Pro Mini boards, running at 3.3V-only.ĭue to the small form factor and pinout, the board can also be used as a MAX3421E USB Host breakout board. And the board is of course compatible to the USB Host library that we have added a lot of features to, such as PS3 and PS4 controlling. The mini version makes it possible to add the USB Host functionality to Arduino Pro Mini projects by stacking the board on top of the Arduino. The USB Host Shield Mini from is a compact version of the well known USB Host Shield that we have been using for a lot of our USB Host development on the Arduino.
