What is the Neutrino?
The Neutrino is an inexpensive, open source, miniaturized version of the Arduino Zero!
Featuring a 32-bit ARM processor running at 48MHz, and boasting 32K of ram, the Neutrino is far more capable than your typical Arduino. And because it has the same processor and pinout, all libraries written for the Zero will work on the Neutrino without any modification!
Finally, being open-source, you're free to modify it as you wish and integrate it into your own designs - without ever needing to pay any royalties or licensing fees!

Programming is easy! Like most Arduinos, you simply plug the board into your PC using a MicroUSB cable, select the board you want to program, and hit the upload button in the IDE when you're ready. The Neutrino ships with the Zero bootloader installed, and most of the time it will auto-reset when the USB serial port is opened by the IDE, but in the event that this fails, you can always hit the reset button on the board to force it to enter bootloader mode after your program finishes compiling.
The Neutrino features a convenient power multiplexing circuit, so you can power it from USB or a battery, and it will switch between them automatically. You can also power the Neutrino directly with a 3.3V regulated supply.
The Neutrino can also supply power to USB devices when acting as a USB host, but in this case you will need to supply 5V to the VIN pin.
A 500mA resettable polyfuse protects the Neutrino and your PC if too much current is being drawn.
Like most Arduinos, a green LED is connected to pin 13. This can be used as a status indicator, and on the Neutrino it functions as a power indicator as well; coming on automatically when power is applied to the board.
Say goodbye to the Tone() command forever! Turn your Neutrino into a virtuoso by connecting an amplifier to pin A0 an using the Audio library to play .WAV files with the built-in DAC!
LiPo charger compatible
Need to use your Neutrino on the go? The Neutrino features the same pinout on its power pins as Adafruit's Pro Trinket, making it directly compatible with their USB LiPo charging backpack!

Risks and challenges
The Neutrino is a fairly straightforward design, and a prototype has already been assembled and tested. I've received a quote for manufacture, taken shipping costs and Kickstarter's cut into account, and selected components that are available in sufficient quantities from reputable distributors. This being the case I don't anticipate any problems delivering the boards on time, and I'll keep you updated every step along the way!Learn about accountability on Kickstarter
