Neutrino 2.0: The tiny 32-bit Arduino Zero compatible!

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!

What's new with version 2.0?

The new version of the Neutrino adds RX/TX pins that were often requested, and is designed to be a bit cheaper to manufacture so that I can continue to offer them at this price point. The USB OTG circuit, which required a costly power multiplexing chip, buffer, and transistor, has been replaced with an inexpensive very low forward voltage diode to isolate the battery from the USB supply. The micro AB connector has also been replaced with a less expensive, but just as sturdy, micro B house part. In addition, the 3.3V LDO regulator, reset button, and status LED have also been changed to house parts. But don't be alarmed; these aren't downgrades. The regulator is a nice modern Texas Instruments part, and the new reset button is slightly larger and has a nicer feel to it!

Programming

Programming is easy! Like most Arduinos, you simply plug the board into your PC using a micro USB 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 can be programmed with the Arduino IDE via USB, or with the Atmel ICE!

Other Features

Status LED

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.

10-bit DAC

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!

Thank you for your support!

Risks and challenges

Last year after a successful Kickstarter campaign I shipped 500 Neutrinos to backers and this year I shipped over 250 Pixels. A prototype of the Neutrino 2.0 has already been assembled and tested, I've received quotes for manufacture, taken shipping costs and Kickstarter's cut into account, and have chosen components that are available in large quantities from reputable distributors. I don't anticipate any problems delivering the boards on time, and I'll keep you updated every step along the way!
