Questions about the Nano 33 BLE Sense

Hardware Nano Family Nano 33 BLE Sense

I think it's time I contributed to Arduino, but I'm having difficulty deciding which board to buy.

This is the second thread in a series of two where I'm asking the community in-depth questions about a pair boards that seem to be impossible to get information on.

  1. I can see that it has a few sensors on board. What's the accuracy like?

  2. How much effort would it take to program a Linux application that takes the transmitted data from BLE and displays it on the terminal? Not particularly an Arduino question but I'm sure someone on here knows the answer.

  3. If I wanted to communicate with a 5V board over serial, what kind of level shifter would I need?

  4. Can the microphone read how loud a sound is in decibels?

  5. How hard is it to use machine learning on embedded devices. It seems like a massive pain, but I have done zero research other than things I've just randomly found.

  6. Can it be a keyboard? The microprocessor has native USB so there must be some way to turn it into an HID.

Thanks.

It is like it says in the sensor's data sheet. Look them up.

About a 4 in effort. (really what sort of answer do you expect?)

Read you other thread with the same question but different processor.

Read This link and see for your self.

Thanks for your help!

Yes, but unfortunately Arduino has not provided support via the standardized Arduino Keyboard library we are accustomed to using with the previous native USB boards such as Leonardo and MKR. There is a non-standard library that comes with the "Arduino Mbed OS Boards" platform of the Nano 33 BLE you can use and it does include an example sketch you can see here:
