The device uses a NINA-B3 series B306 Bluetooth 5 Low Energy module. Arduino Nano 33 BLEĪs you can probably surmise from its name the Arduino Nano 33 BLE features Bluetooth. The Arduino Nano Every uses an ATmega4809 microcontroller, which is an 8-bit controller running at 20MHz.

This is the “entry-level” Arduino Nano, and it is a direct upgrade for the original ATmega328-based design. The new family members are as follows: Arduino Nano Every You can also solder in header pins, the modules are packaged with male Dupont headers for this purpose. This design, which we have also seen on the Seeeduino XIAO and the Raspberry Pi Pico, allows the board to be directly soldered onto another PCB as a surface-mount device. Unlike the original, the newer boards are produced in a “castellated” form factor. The four “new” Arduino Nano boards are packaged in the same 30-pin module as the original Nano.

With a pinout equivalent to the older Nano board and the ability to tap into the huge collection of existing Arduino software and libraries the Nano 33 IoT board has the potential to add new power to old designs and is a great choice for new IoT products. The “33” in the boards’ name refers to this being a 3.3-volt device, as opposed to the original 5-volt Nano. As of this writing, the Nano 33 IoT was the only one of the “new” Nano boards supported on the cloud. This board is also supported on the Arduino IoT Cloud, an IoT infrastructure that makes building IoT projects very simple.

The “IoT” in the board’s name is not only due to the integrated WiFi and Bluetooth connectivity. This low-cost module features a powerful 32-bit processor, integrated WiFi and Bluetooth, and IMU (Inertial Measurement Unit), and onboard RTC (Real Time Clock). One of these boards is the Arduino Nano 33-IoT board. They subsequently released three more “updated” Nano boards with a variety of different onboard peripherals. In 2019 Arduino released the Arduino Every, an updated version of the Nano. As with most Arduino designs, this is an open-source product, so it has been copied by a myriad of other manufacturers. It is essentially the equivalent of the popular Arduino Uno in a smaller form-factor, and it even has a couple of extra analog output pins. The original Arduino Nano was released in 2008 and has become very popular.

Let’s take a closer look at the Nano 33 IoT and see what we can do with it.
