Arduino Nano
It came as a surprise when Arduino launched a whole new family of compact boards at competitive prices: Nano Every, Nano 33 IoT, Nano 33 BLE and Nano 33 BLE Sense.
Although based on different MCUs, they all share the same Arduino Nano form-factor with castellated pads and aggressive prices. The Arduino 33 BLE was sampled by Arduino. The other boards were bought. |
Hardware
The new entry board remains 8 bits and 5V-compatible.
|
Software
The IoT-capable boards use dedicated libraries.

Debugging
The 32-bit boards provision pad for an SWD connection. However, soldering the cables isn't very clean.
I would have preferred the standard 2x5 0.05" pad found on other boards. A detailed step-by-step procedure is available at the Hackster.io project Arduino Nano 33 IoT Debugging. Click to enlarge

Conclusion
The compact form-factor, the castellated pins and the competitive prices make the new Arduino Nano boards very interesting modules.
However, the examples provided remain rather basic. For example, the Nano 33 BLE Sense has no project that combines all the sensors and no related iOS or Android app. Users should refer to the Arduino project hub instead. |
