| The code for the 8u2 is based on LUFA, Dean Cameras totally awesome USB-AVR library that has great examples and documentation. Its also completely open source. | The code for the 8u2 is based on LUFA, Dean Cameras totally awesome USB-AVR library that has great examples and documentation. Its also completely open source. | ||

| + | ===== Can I get to the other pins on the 8u2? ===== | ||
| + | |||
| + | In the Uno, no extra pins are brought out to headers. If you want to poke around with chips like the 8u2 we suggest using something like the Teensy! | ||

| Arduino is now FCC certified! That means that the board by itself passes FCC certification for electromagnetic emissions. It does **not** mean that your project is FCC certified. The moment you change the Arduino, its no longer FCC certified (although we'd like some back-up documentation on this) | Arduino is now FCC certified!

| + | ====== Why not just use the '8u2 as a programmer? ====== | ||
| + | |||
| + | While it is possible that the 8u2 could act as a full ISP programmer there are a few reasons why its good that it isn't | ||
| + | |||
| + | - Giving beginners access to a full ISP programmer will result in bricked chips. There's no risk of messing up the Arduino chip beyond recognition if its just being bootloaded | ||
| + | - Having the chip act only as a USB/serial passthrough simplifies the firmware so that the chip has only one function instead of having to have it do double duty as programmer -and- serial interface (think about it, its not easy) | ||
| + | - Backwards compatibility - the Arduino chips can still be programmed with FTDI breakout boards or cables, making it easy for people to breadboard or make clones. | ||
| ====== Are Shields still going to work? ====== | ====== Are Shields still going to work? ====== | ||
| All previous shields should still work perfectly fine as the header spacing is the same, the core chip is the same and the location of parts is the same. In fact, some should work better because the 3V supply has been upgraded (see next point) | All previous shields should still work perfectly fine as the header spacing is the same, the core chip is the same and the location of parts is the same.

| + | ====== Will enclosures, plates, etc still work? ====== | ||
| + | |||
| + | Yup! The Uno is physicially the same size and layout as previous Arduinos. The mounting holes are in the same location. There is an additional mounting hole as well, now. | ||
