Poll: Are You Interested in Roadtesting the Arduino NANO 33 IOT Dev Board?

The Arduino Nano 33 IoT is the easiest and cheapest point of entry to enhance existing devices (and creating new ones) to be part of the IoT and designing pico-network applications. Whether you are looking at building a sensor network connected to your office or home router, or if you want to create a BLE device sending data to a cellphone, the Nano 33 IoT is your one-stop-solution for many of the basic IoT application scenarios.

 

Arduino Nano 33 IOT

A few facts ....

 

  • SAMD21 CortexRegistered-M0+ 32bit low power ARM MCU
  • Radio module u-box NINA-W10, secure element ATECC608A
  • Operating voltage of 3.3V
  • Clock speed is 48MHz, CPU flash memory is 256KB, SRAM is 32KB
  • 11 PWM pins, 1 UART, 1 SPI, 1 I2C
  • 8 (ADC 8/10/12bit) analogue input pins, 1 (DAC 10bit) analogue output pins
  • LSM6DS interial measurement unit (IMU)
  • Length is 45mm, width is 18mm, weight is 5g (with headers)

 

Here's some other resources:

  • It would be a nice board to play with.

  • That's so neat! I've been really impressed with the SAMD21 boards and having WiFi and Bluetooth on the same tiny board is really cool. The IMU is almost the "Hello, world!" of BT connected sensors so happy to see that included too image

  • I already have this (Nano33 IOT) as well as the Nano33 BLE Sense. I got it a couple of months after they were launched by Arduino.

     

    The main mcu is a SAMD21 and the one that gives the product its "IOT" capabilities is an ESP32 communicating via SPI (which they call WifiNINA https://www.arduino.cc/en/Reference/WiFiNINA )

     

    Last time I tried it out, the BT libraries weren't yet very mature. There's also the issue of power management; being a dev board you don't really have much control over the connection of the peripherals to shave off some milliamps when running on batteries--I'd be interested reading about how this will be tackled!

     

    Apparently they also have a DC-DC regulator instead of a linear regulator, which should increase efficiency (and BOM count) when integrating with high voltage circuits like robots or motors (you can just feed all of them via the same 12v source without having to regulate it yourself down to 3v3).

     

    I'm glad this is being roadtested as I wanted to know what other more experienced engineers would be able to do with this!

     

    Looking forward to seeing the reports image

  • Other:  Yes but no.  I've got too many irons in the fire at the moment.  I will be trying out TinyML.

  • Yes. I really do.

     

    However-

     

    I'm in a Design Challenge and pretty much morally committed to a Project14... Time may be difficult.

     

    Furthermore, I'm not too sure how to RoadTest this board. TinyML? Maybe, if I can figure that out from the Edge Impulse Wkshp.

     

    I'm also not too great at IoT.
