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

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:

its for research purposes..

i see..actually the word product that i used is misleading...we want to make a smart watch for research purposes (like watch accelerometer values) and it looks difficult to find cheap watches with open API. So, a development of a smart watch with 2-3 basic functions looked more viable.

very interesting! so, to see if i understand this correctly, i buy a cheap all-in-one smart watch and then flash it, with for example Arduino Core (using STM32 board as programmer) and then do whatever i want with the sensors and flash any sketch i want (like the arduino style sketches and libraries i use to read data from arduino/esp32/esp8266 etc)..right?

Not sure what you mean by that?

The question seems backwards: the chip is just a chip - it neither knows nor cares what board it's on.

If you want to know if Sparkfun, Adafruit, or any other 3rd party has a board with an nRF chip on it, then you will have to ask that 3rd party.

Sparkfun certainly do have one - see:

i want to use Nordic's chip with DK from Arduino/Sparkfun/Adafruit..so, before i go to Arduino forums for DK's problems, i want to be sure Nordic's chip supports this kind of DKits.

+99 to what haakonsh said!

[quote userid="79637" url="~/f/nordic-q-a/47156/use-nrf52-for-smartwatch-spi"]Our team is considered doing their own smart watch[/quote]

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 ...

😮

IMHO, if you're going to make an actual product I suggest that you stick to our DKs and SDKs for development.

1. Sure you can use Adafruits SDKs and DKs, but we wont be able to help you with your development.

2. You need at least one nRF52 DK for debugging, and if you want our help then you need to use a HW plattform that we are familiar with, like our DKs. You're free to choose whatever tools you'd like, but we can only help you if you use ours. You do not need our permission to put your product on the market, but you will need to certify with ETSI, FCC, KCC, etc and BT SIG if you use BLE.

There are some nice nRF52 smartwatches on Amazon which you can use as a starting point, complete with code see this github nRF5x link

Maybe - but the point is: it is certainly not Nordic!

(I think it may be Sparkfun?)

EDIT

or Adafruit?

actually its not exactly arduino stuff because it is not arduino...it is arduino CORE (like an sdk, more here).

RE: use nrf52 for smartwatch spi

Note that Arduino is all 3rd-party stuff - nothing to do with Nordic.

So for questions about Arduino and its capabilities, you will need to go to the Arduino forums.

But the nRF52 itself can certainly interface with anything having a standard SPI interface.
