Hello,
I'm currently doing a machine learning based IOT project. So I came to know about Arduino Nano 33 BLE. Since I'm a new learner, I'm confused between Arduino Nano and Arduino Nano 33 BLE. Can we use Arduino Nano connected with a Bluetooth module for embedded machine learning projects instead of Nano 33 BLE?
Thanks.
The two are very different things despite having a similar name.
No. The processor is not powerful enough and it has a very small amount of memory.
the only thing in common between the two is the size and header pin locations.
Hello @Grumpy_Mike, @Juraj
Thank you for your quick reply. Adding to that I have another doubt.
Will Arduino Nano 33 BLE supports TinyML models? I'm currently planning to do a project on predicting the life cycle of the battery using edge impulse. So I thought of buying Arduino Nano 33 BLE. But in the official website, it states that only Arduino Nano 33 BLE Sense is a supported board. I came to know that the difference between these two boards is that the Nano 33 BLE Sense has some inbuilt sensors in it. In my use case I'm not going to use any of that inbuilt sensors.
Can I use Arduino Nano 33 BLE instead of Arduino Nano 33 BLE Sense for doing TinyML projects?
Thanks.
This project shows them both being used
As you have already found, the only difference between the Nano 33 BLE and the Nano 33 BLE Sense is that the Sense has some additional sensors.
The reason you will often see the Sense used in machine learning tutorials and demos is because the fact that it already has some input built in simplifies the creation of that content because the authors don't need to spend time on explaining how you should source and connect some external input devices.
Those sensors make the Nano 33 BLE Sense a good choice for projects where you happen to need the sensors Arduino chose to put on the board. But all the other capabilities of the boards are identical and you always have the option of connecting external input devices to the board for whatever your needs might be.
The microcontrollers on the two boards are identical, so either one is just as capable for your particular machine learning application.
Hi @in0
Thanks for your reply. Now I got it.
You are welcome. I'm glad if I was able to be of assistance. Best wishes for success with your project!
There are many major differences. Arduino Nano is based on 8-bit ATmega328P SMD chip. Arduino nano 33 BLE is based on a 32-bit ARM processor. 33 BLE has a in-built bluetooth module and a 9-axis MPU. arduino nano has none of these. If you're looking for a board for machine learning project, you must go with Nano 33 BLE, not the ordinary Arduino Nano.
