Re: Protoneer Nano-Arm #ubitx


I ordered one yesterday but there seems to be a long delivery time?

That sounds like a very good solution for a simple upgrade.

Protoneer has a NANO-ARM board offering for $10 + $5 (US) shipping.
This may be a viable low cost pin compatible upgrade to the nano board on the Radunio with a direct board swap out.
This will give more headroom for coding +more features and still work in the Arduino IDE environment.

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
