We love Arduino Nano's but always wanted a bit more performance and memory.
So we decided to source an Arduino Nano compatible board with an upgrade micro-controller that is similar to an Arduino Zero.
- 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
Hardware
Schematic
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)

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
