Omschrijving

This small, robust and powerful board has WiFi and Bluetooth connectivity that combined with its low power architecture makes it a practical and cost-effective solution for your connected projects.

Arduino Nano33 IoT is fully compatible with the Arduino IoT Cloud and supports full TLS secure transport: the ATECC608A crypto chip stores the cryptographic keys in hardware, offering a very high level of security for this class of products. The integration with the Arduino IoT Cloud offers also a very efficient way of setting up online dashboards with little coding and minimal effort.

In the same iconic size of the Arduino Nano, the Arduino Nano 33 IoT hosts an Arm Cortex-M0+ SAMD21 processor, a WiFi, and Bluetooth module based on ESP32, a 6 axis Inertial Measurement Unit (IMU) and a crypto chip that can securely store certificates and pre-shared keys. The board can either be used in a breadboard (when mounting pin headers) or as an SMT module, directly soldering it via the castellated pads.

Technical Specifications

This board is based on the SAMD21G18A microcontroller.

Clockup to 48MHz

Please note: Arduino Nano 33 IoT only supports 3.3V I/Os and is NOT 5V tolerant so please make sure you are not directly connecting 5V signals to this board or it will be damaged. Also, as opposed to Arduino Nano boards that support 5V operation, the 5V pin does NOT supply voltage but is rather connected, through a jumper, to the USB power input.

To avoid such risk with existing projects, where you should be able to pull out a Nano and replace it with the new Nano 33 IoT, we have the 5V pin on the header, positioned between RST and A7 that is not connected as the default factory setting.

This means that if you have a design that takes 5V from that pin, it won’t work immediately, as a precaution we put in place to draw your attention to the 3.3V compliance on digital and analog inputs.

5V on that pin is available only when two conditions are met: you make a solder bridge on the two pads marked as VUSB and you power the NANO 33 IoT through the USB port.

If you power the board from the VIN pin, you won’t get any regulated 5V and therefore even if you do the solder bridge, nothing will come out of that 5V pin.

The 3.3V, on the other hand, is always available and supports enough current to drive your sensors. Please make your designs so that sensors and actuators are driven with 3.3V and work with 3.3V digital IO levels.

5V is now an option for many modules and 3.3V is becoming the standard voltage for electronic ICs.

The communication on WiFi and Bluetooth is managed by a NINA W102 ESP32 based module.

The module is connected to the SAMD21 microcontroller with an SPI BUS and a serial port through the following pins:

Some of the NINA W102 pins are connected to the 15+15 pins headers/pads and can be directly driven by the module's ESP32; in this case, it is necessary that the SAMD21 corresponding pins are aptly tri-stated.

Below is a list of such signals:

8PB0931GPIO33A5/SCL
7PB0835GPIO5 / GPIO19A4/SDA

The IMU is an LSM6DS3 and it is managed through I2C.

 

The crypto chip is an ATECC608A and has a supporting library that is used by the WiFiNINA library.

 

The board has two 15 pins connectors - one on each side -,  pin to pin compatible with the original Arduino Nano.

(*), As opposed to other Arduino Nano boards, pins A4 and A5, have an internal pull-up and default to be used as an I2C Bus so used as analog inputs is not recommended. Opposed to Arduino Nano boards that support 5V operation, the 5V pin does NOT supply voltage but is rather connected, through a jumper, to the USB power input.

 

On the bottom side of the board, under the communication module, debug signals are arranged as 3x2 test pads with 100 mil pitch. Pin 1 is the bottom left one with the USB connector on the left and the test pads on the right
