Description

Featuring a 32-bit ARM processor running at 48MHz and boasting 32K of ram, the Neutrino is far more powerful than your standard Arduino!

Also, being open-source, you’re free to modify and integrate it into your own designs – without ever needing to pay any royalties or licensing fees!

Technical Details

• Microcontroller: Atmel ATSAMD21G18 ARM Cortex M0+
• Clock speed: 48 MHz
• Operating voltage: 3.3V
• I/O pin limits: 3.3V, 7 mA
• Digital I/O pins: 14, with 12 PWM
• Analog input pins: 6, 12-bit ADC channels
• Analog output pins: 1, 10-bit DAC
• Flash memory: 256 KB
• SRAM: 32 KB
• Voltage regulator: TLV702, 3.7V – 5.5V input / 3.3V, 300mA output
• Dimensions: 1.4 x 0.7″ (36mm x 18mm)

Installation

To use the Neutrino in the Arduino IDE, first install the board files for the Arduino Zero from the boards menu. The board will then be detected as a Zero on one of the COM ports automatically when you plug it in.

Then, to program it, you should select the Zero’s NATIVE port on the boards menu.

The reason the PROGRAMMING port isn’t used is because that’s connected to a second debug chip on the Zero which the Neutrino doesn’t feature because the IDE doesn’t support it!

Troubleshooting

If you ever find that you cannot program your board, chances are your program has locked up, rendering the microcontroller incapable of polling the USB port for a serial connection. In this case, simply double tap the reset button, which will force the board to remain in bootloader mode until it is reset again, or reprogrammed.
