use nrf52 for smartwatch spi

[jimkaragian]

Dear support,

Our team is considered doing their own smart watch, so i found that nRF52 chip is a nice solution. Just before we start, i would like to do some basic questions so we will not spend much time to an dead end.

So my questions are:

1) i see that nRF52 supports SPI. But can i use this protocol with Arduino IDE (with this library for example https://github.com/adafruit/Adafruit_nRF52_Arduino ) that i am more familiar? I want to connect some accelerometer, oled and maybe 1-2 more sensors.

2) can i use this chip (click here)  or like this (click here) or this instead of the big development boards? Do we need a permission to make a final product?

Which module from the above you suggest? (use in Greece, Europe)

Thank you in advance

Is that as a commercial product, or as a school/hobby project?

You need to think very carefully about the commercial viability if you're thinking of developing a saleable product ...

its for research purposes..

Then you really don't want to get bogged down in developing the device! That could easily hog all your time and budget - especially as you don't seem to be experienced in this area?

How about something like this:

actually this looks very nice project...

it is open course so we can manipulate the whole thing, and at the same time you can easily get raw sensor accelerometer data (as i found in the documentation)..also its cheap enough..

thnx for the info
