Overview

NANO-ARM-Bottom1.jpg

We loved Arduino Nano's but always wanted a bit more performance and memory.

So we decided to create a Arduino Nano compatible board but with an upgrade micro-controller that is similar to an Arduino Zero.

The NANO-ARM has the following features:

  • Runs at 48MHz (Atmel SAMD21)
  • 256KB FLASH Memory
  • 32KB RAM
  • Pin compatible with Arduino Nano but runs at 3.3V
  • SAMD21 micro-controller same as used on a Arduino Zero's.
  • Built in USB
  • Arduino Zero bootloader pre-loaded.
  • 20 I/O pins with 5 extra pins that can be used for I2C/SPI or I/O
  • 6 Analog Pins(ADC) with 12-bit resolution (4096 resolution point vs Arduino Uno's 1024)
  • 1 Digital to Analog(DAC) pin with 10-bit resolution.
  • Designed and Manufacture in New Zealand

Power Management

3.3V Regulation is done with a NCP551 Low-Dropout Voltage regulator.

  • Input Voltage 12V max
  • Output currnet 150mA
  • Very low quiescent current of 4.0uA(Typical)

Datasheets

Arduino IDE

Programming a NANO-ARM

NANO-ARM's are 100% Arduino Zero compatible and the programming process is the same.

This is the guide as provided with the Arduino Zero : Programming Guide

Pin Mappings

Pin mappings for Arduino Zero / NANO-ARM is avaialable from the Arduino Github repository at: https://github.com/arduino/ArduinoCore-samd/blob/master/variants/arduino_zero/variant.cpp

Serial Ports

In Arduino the following has changed:

  • Serial Object is connected to Pin D0 and D1
  • SerialUSB Object is connected to the USB serial port that is visible to computers.

Versions

Version 1.02

Added USB test pads for testing.

Version 1.01

Initial release.
